What is a disorder of the circulatory system?

Disorders of the Circulatory System. A disorder is defined as a state of irregular functioning of the body. The disorders of the circulatory system could be defined as any ailment which affects the heart, blood vessels, and the blood cells.

What is the term for a condition where the heart doesn't pump enough blood to the tissue cells in the body

Heart Failure . Heart failure may be defined as a chronic condition when the heart doesn’t pump sufficient blood to the tissue cells in the body. It is sometimes known as congestive heart failure because the main symptom of heart failure is lung congestion. Heart failure may be caused by the following risk factors:

What is the difference between systolic and diastolic blood pressure?

Systolic blood pressure – It is defined as the pressure that is created in the arteries when blood flows through arteries to the rest of the body when the heartbeats. Diastolic blood pressure– It is defined as the pressure created in the arteries when the heart relaxes between the beats.

What is the definition of diastolic blood pressure?

Diastolic blood pressure– It is defined as the pressure created in the arteries when the heart relaxes between the beats. If the normal blood pressure is higher than 140 over 90 or higher, it leads to hypertension. It has no signs and symptoms.

What is the term for the deposition of waxy substances in the blood vessels that supplies the blood to the heart muscle

Intake of large amounts of fat-rich foods. Coronary artery disease is also termed as atherosclerosis. Coronary Artery Disease is the disease which is caused by the deposition of waxy substances in the blood vessels which supplies the blood to the heart muscle and this deposition leads to the blockage of the blood flow.

What are some examples of circulatory system diseases?

Many circulatory system diseases are linked to each other. For example, high blood pressure damages the blood vessels, which can lead to other circulatory problems. The narrowing of blood vessels caused by high cholesterol increases the likelihood of a person getting a blood clot.

Can circulatory system diseases be managed?

Without immediate medical attention, stroke, heart attacks, and aneurysms can have devastating effects. Other diseases can be managed. For example, doctors typically treat angina pain with tablets that increase the blood flow to the heart.

What is the blood circulatory system?

Outlook. The blood circulatory system, also called the cardiovascular system, consists of the heart and the blood vessels that run throughout the body. It delivers nutrients and oxygen to all cells of the body. The oxygen we breathe gets mixed into the blood in the lungs, and the heart pumps this blood to all parts of the body.

What are the diseases that affect the cardiovascular system?

The cardiovascular system is composed of the heart and blood vessels. Diseases that can affect the circulatory system include: 1. Atherosclerosis. Atherosclerosis is a hardening of the arteries. It is typically caused by a diet high in fat, which leaves fatty deposits on the lining of the blood vessels.

Do circulatory diseases link to each other?

Various circulatory diseases are linked to one another. While scientists do not know what causes all of these diseases, there are things that individuals can do to reduce the risk of developing them. Many circulatory system diseases are linked to each other.

How many chambers does the heart have?

Frequently Asked Questions (FAQs) on Human Circulatory System

Q.1. What is the human circulatory system? Ans: Human circulatory system is one of the systems of the body that comprises the heart, blood and blood vessels like arteries, veins and capillaries. Blood runs through the blood vessels to transport different nutrients and oxygen to different parts of the body.

Human Circulatory System: A Brief Overview

The circulatory system, also known as the cardiovascular system is one of the most important organ systems of the body that primarily deals with the circulation of blood in the body and transports nutrients, oxygen, hormones, carbon dioxide, blood cells which help the body not only to provide nourishment to different sections of the body but also help in fighting diseases, maintain pH and temperature and overall homeostasis.

Disorders of the Circulatory System

Disorders are the functional irregularities of the system. They may cause some severe implications on the human body that include death. Genetic disposition, lifestyle choices and stress level are some of the factors that create disorders in the circulatory system.

Hypertension

When blood flows through arteries it puts some pressure against the wall of the artery itself. This pressure is known as blood pressure. In human beings, the normal range of blood pressure is 120/80 mm Hg where 120 is the systolic blood pressure and 80 is the diastolic blood pressure.

Atherosclerosis and Arteriosclerosis

Atherosclerosis is the narrowing of the arteries which takes place due to the deposition of cholesterol, fats, etc. on the inner lining of the arteries leading to the formation of plaques. As a result of deposition, the lumen of the artery decreases in diameter. Thus, for a continuous flow, the blood has to be pushed forcefully.

Angina Pectoris

Angina Pectoris is a condition where chest pain occurs as the heart receives insufficient oxygen and nutrients through the blood vessels. It usually results from the arteriosclerosis of the coronary arteries.

Heart Block

Heart block is a group of disorders of the circulatory system characterized by the presence of some obstruction or blocks in the electrical pathway of the heart. Due to the obstruction of the electrical pathway, the conduction of electrical impulses slows down resulting in improper contractions.

Heart Attack

If there is a formation of a clot or thrombus in an already narrowed coronary artery, the blood supply may completely stop to some part of the heart. This part of the heart may die due to a lack of oxygen. This is called a myocardial infarction or heart attack. It may prove fatal if the affected area is large.

What is the circulatory system?

The circulatory system, also called the cardiovascular system, includes the heart and the network of blood vessels that circulate blood throughout the body. Several diseases and disorders can affect this system. Below are some of the most common pathologies.

What is the most common type of heart disease?

Coronary Artery Disease is the Most Common Type of Heart Disease. Coronary artery disease (CAD) develops as cholesterol and plaque accumulate on the interior walls of coronary arteries. This buildup is called atherosclerosis. The arteries become increasingly blocked, compromising the flow of oxygen-rich blood to heart tissue.

How does an abdominal aortic aneurysm affect the body?

An Abdominal Aortic Aneurysm Affects the Body’s Main Supplier of Oxygenated Blood. Oxygenated blood pumped from the left ventricle of the heart enters the aorta. The aorta is the largest artery. It branches into the systemic arteries that supply most regions of the body. In an abdominal aortic aneurysm, the wall of the aorta weakens in the area ...

Which blood vessel is responsible for carrying oxygen-rich blood away from the heart?

The aorta is the largest blood vessel in the body, carrying oxygen-rich blood away from the heart. 2. Mitral Valve Prolapse Affects the Valve Between the Left Atrium and the Left Ventricle of the Heart. The mitral valve is one of the four heart valves.

What is another word for heart attack?

4. "Myocardial Infarction" is Another Way to Say "Heart Attack". A myocardial infarction, or heart attack, happens when blood flow to heart tissue is obstructed. This can occur from a buildup of plaque in the walls of coronary arteries (as in coronary artery disease).

What is the cause of myocardial infarction?

A myocardial infarction, or heart attack, happens when blood flow to heart tissue is obstructed. This can occur from a buildup of plaque in the walls of coronary arteries (as in coronary artery disease). Because oxygenated blood cannot reach part of the heart muscle that muscle dies or is damaged.

What happens when blood flow to the heart is obstructed?

A myocardial infarction, or heart attack , happens when blood flow to heart tissue is obstructed. This can occur from a buildup of plaque in the walls of coronary arteries (as in coronary artery disease). Because oxygenated blood cannot reach part of the heart muscle that muscle dies or is damaged. The heart weakens and suffers a severe decrease in pumping ability. Signs of a heart attack include chest discomfort (pressure, squeezing, or pain), shortness of breath, nausea, and lightheadedness.

What are the symptoms of a circulatory system disease?

What is the cause of heart disease?

Heart disease, or coronary artery disease, occurs when the blood vessels that supply oxygen to the heart narrow and stiffen. Smoking, an unhealthy diet, stress, and a sedentary lifestyle all increase the risk of heart disease. A heart attack or stroke can occur if the condition is untreated.

What is peripheral vascular disease?

Peripheral vascular disease occurs when the arteries and veins supplying the lower extremities narrow and stiffen from the buildup of plaque. Common symptoms of peripheral vascular disease include: Pain with movement. Tingling, burning, or numbness in feet when resting.

What are the components of the circulatory system?

The important components of the circulatory system have different functions. The blood vessels transport blood to and from the heart, the heart pumps oxygenated blood to the body, and the oxygen, gases, and nutrients exchange in the capillaries. Anything that affects the integrity of the tubing can impair the health of the circulatory system.

What causes arteries to narrow?

Arteriosclerosis is a common disease of the circulatory system caused by the buildup of fat, cholesterol, or other substance in the artery wall. Deposits in the artery cause the vessel to stiffen and narrow. Diabetes, high cholesterol, smoking, and high blood pressure can result in stiff arteries that restrict blood flow through the heart.

What is the term for a high blood pressure?

Hypertension. Hypertension , or high blood pressure, occurs when a high force of blood presses against the artery walls over time. This condition can develop from a diet high in salt, smoking, kidney disease, or some other underlying medical condition.

What is the Circulatory System?

Picture a highway bringing traffic in and out of a city. There are large, multi-lane highways that connect distant parts of the city, with roads branching from the exits. The smaller roads bring people and goods to every corner of the city. Although we're not filled with cars and concrete, the circulatory system has a similar function in our body.

Cardiac Arrest and Myocardial Infarction

As you stand outside your local emergency room, emergency technicians rush in an unconscious patient. Nurses shout 'Clear!' and try to shock the patient back to life. This person's heart has stopped during sudden cardiac arrest.

Stroke

Similar to a heart attack, a stroke happens when blood flow to the brain is cut off due to a clogged artery. Like the heart, without oxygen your brain cells begin to die. The longer the brain lacks oxygen, the greater the damage will be.

What is the most infamous disorder of the circulatory system?

Heart Attack . One of the most infamous disorders of circulatory system is the heart attack . In medical terms, heart attacks are called as Myocardial Infarction. When enough blood does not reach the heart due to blockages, a heart attack happens, which damages the heart muscle.

What is the circulatory system?

The circulatory system seen in humans is a complex mechanism. It functions 24/7, ensuring that there is a proper flow of blood to all parts of the body. The heart beats nonstop and there is an exchange of gases and nutrients that happen.

What happens when your heart beats nonstop?

The heart beats nonstop and there is an exchange of gases and nutrients that happen. Interruptions and blockages in the blood vessels affect the way the heart pumps blood. Sometimes, these can cause some major complications leading to heart disease and even stroke.

Does high blood pressure cause heart disease?

Often called as the silent killer, high blood pressure does not show any symptoms. High blood pressure often damages the heart and leads to heart diseases and can also affect other vital organs.

What is the difference between diastolic and systolic pressure?

Systolic pressure is the force inside the arteries when the heart beats. The diastolic blood pressure is measured when the heart is at rest, i.e. in between the heartbeats. In high blood pressure, the force with which the heart pumps out blood is high. If the blood pressure, of an individual, is at 140/90 mmHg, then it indicates hypertension.

What does high blood pressure mean?

In high blood pressure, the force with which the heart pumps out blood is high. If the blood pressure, of an individual, is at 140/90 mmHg, then it indicates hypertension.

What is plaque in the heart?

Most often it is also called as atherosclerosis. It primarily affects the blood vessels that supply blood to the heart, which are the arteries. The arteries get hardened because of the deposition of plaque. Plaque is generally made up of fat, cholesterol, calcium, clotting agents, cell debris, etc. which are normally found circulating in the blood. ...

What is a thrombus in the circulatory system?

Thrombus is a solid mass or plug of blood constituents (clot) in a capillary. This mass may obstruct (wholly or only in part) the vessels in which it forms, or it may be removed and reached some other place in the circulatory system, in which case it is called an embolus. Thrombosis is the formation of thrombus. Thromboembolism is the leading cause of deaths in western civilization.

What is a clot in the heart called?

Clot or blockage of a blood vessel in the heart by an embolus (or by locally formed thrombus) triggers necrosis or damage to part of heart muscles, a condition is known as a cardiac arrest or technically myocardial infarction, Cardiovascular disease is due to disruptions of the control system of the heart with accompanying arrhythmias, especially ventricular fibrillation.

What is leucaemia caused by?

It is the outcome of unrestrained production of white blood cells (leucocytes). This is brought on by malignant mutation of a myelogenous or lymphogenous cell. The Leucaemia is usually characterized by largely increased numbers of unusual white blood cells in the circulating blood.

What is Cooley's anaemia?

It is a genetically transferred haemoglobin abnormality. It is defined by the presence of microcytes, by splenomegaly (enhancement of spleen) and by changes in the bones and skin. The blood of these patients is to be replaced frequently, with regular blood.

Is atheroma a degenerative arterial change?

It is existing together atheroma and arteriosclerosis; atheroma is the deposition of tough yellow plaque of lipoid product in the innermost layer of the arteries, which might be because of the high level of cholesterol in the blood. Arteriosclerosis is a degenerative arterial change related to adva ncing age.

What is the condition of high blood pressure?

Blood might then be retained in the heart and lungs, often leading to a deadly condition called heart disease.

What is it called when the brain is blocked by a thrombus?

If the normal flow of blood is blocked by an embolus (or a locally formed thrombus), in a capillary in the brain, and triggers necrosis, or death, of the surrounding neural tissue (owing to the absence of O 2 ), the condition is called a stroke or cerebral infarction. The symptoms of the stroke differ depending upon the part of the brain that has been damaged.
