What is the organs of cardiovascular system? The circulatory system consists of three independent systems that work together: the heart (cardiovascular), lungs (pulmonary), and arteries, veins, coronary and portal vessels (systemic).
What are the five functions of the cardiovascular system?
Ways to check the health of your cardiovascular system organs include:
- Electrocardiogram (EKG).
- Blood tests.
- Echocardiogram (using sound waves to make a picture of the heart and valves).
- Stress tests (treadmill test, sometimes with imaging).
- Cardiac CT (using X-rays and a computer to make cross-sectional images).
Which components make up the cardiovascular system?
There are three types of blood vessels in the human body:
- Artilleries – They carry blood away from the heart. ...
- Veins – They carry deoxygenated blood from the body and oxygenated blood from the lungs into the heart.
- Capillaries – Arteries break down into a minuscule network of capillaries, which are the smallest blood vessels and present in the lungs and muscles.
What major organs are involved in the circulatory system?
Your circulatory system is made up of several parts, including your:
- Heart. This muscular organ works to pump blood throughout your body via an intricate network of blood vessels.
- Arteries. These thick-walled blood vessels carry oxygenated blood away from your heart.
- Veins. These blood vessels carry deoxygenated blood back toward your heart.
- Capillaries. ...

It is made up of three main parts: the heart, pulmonary circulation, and systemic circulation. Let's review the terms we learned today about each of these three parts ...
What is the thin inner lining of the heart?
The endocardium is the thin inner lining of the heart wall. To help you remember where the endocardium is located, notice that 'endo' sounds like 'inside,' and the endocardium is inside the heart. The myocardium is the thick, muscular, middle layer of the heart wall.
Which valve prevents blood from flowing backwards from the right ventricle into the right atrium?
The tricuspid valve has three flaps and prevents blood from flowing backwards from the right ventricle into the right atrium. The mitral valve is a 2-flapped valve that separates the left atrium and the left ventricle. The endocardium is the thin, inner lining of the heart wall.
Which valve separates the right atrium and the left ventricle?
On the left side of the heart, the mitral valve is a 2-flapped valve that separates the left atrium and the left ventricle.
Which artery carries deoxygenated blood to the lungs?
After passing through the right atrium and ventricle, the blood is pumped into the pulmonary artery, which carries deoxygenated blood to the lungs. The pulmonary artery is special because it is the only artery in your body that carries deoxygenated blood.
What is the layer of tissue that surrounds the heart called?
On top of the myocardium on the outside of the heart, there is a layer of protective tissue called the epicardium. Any medical term that includes the prefix 'epi-' will always be talking about something that is on the outside, just like the epidermis is the skin that is on the outside of your body.
Overview
Your heart and many blood vessels in your body make up your cardiovascular system or circulatory system. Your heart uses the far-reaching, intricate network of blood vessels to deliver oxygen and other necessary things to your whole body.
Function
The function of the cardiovascular system is to make sure your body gets the oxygen, nutrients and other things it needs and gets rid of things it doesn’t.
Anatomy
Your heart is located in the middle of your chest. It connects to your blood vessels. They go everywhere throughout your body so they can get oxygen and nutrients to every part of your body. They also take waste away from all the cells in your body.
Conditions and Disorders
Many of the problems with the components of the cardiovascular system have to do with slowdowns or blockages in the blood vessels. Since your blood vessels supply your entire body with oxygen, a blockage in any of the blood vessels makes it harder to deliver that oxygen.
Care
You can help keep your heart and blood vessels healthy in a number of ways, including:
Frequently Asked Questions
Your heart and blood vessels, the parts of the cardiovascular system, are important because they bring oxygen, nutrients and other good things to every cell in your body. They also take away carbon dioxide and waste. This supply of nutrients and the removal of waste is the main function of the cardiovascular system.
What is the Cardiovascular System?
The cardiovascular system definition is an organ system that transports blood around the body. The cardiovascular system is always working, even when a person is resting or asleep. It increases its function to match the demands of our energy, such as when we play basketball or go for a run.
Cardiovascular System Function
What does the cardiovascular system do? The primary function of the cardiovascular system is to pump blood throughout the body. Blood is an important type of connective tissue and has the unique function of transporting oxygen and nutrients to distant parts of the body.
Parts of the Cardiovascular System
There are two main parts to the cardiovascular system: the pulmonary circuit and the systemic circuit. The pulmonary circuit carries deoxygenated blood returning to the heart from the body out to the lungs. Here, carbon dioxide in the blood diffuses into the lungs to be exhaled, and oxygen in the lungs diffuses into the blood.
Cardiovascular System Organs
There are several major organs and tissues in the cardiovascular system. The three main ones include:
What is the cardiovascular system?
Updated September 01, 2019. The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from the body. This system is comprised of the heart and the circulatory system. Structures of the cardiovascular system include the heart, blood vessels, and blood. The lymphatic system is also closely associated with ...
Which system of the body transports blood and signals between the different organs?
The circulatory system transports blood along pulmonary and systemic circuits. The pulmonary circuit involves the path of circulation between the heart and the lungs.
What is the lymphatic system?
The lymphatic system is a vascular network of tubules and ducts that collect, filter, and return lymph to blood circulation. Lymph is a clear fluid that comes from blood plasma, which exits blood vessels at capillary beds. This fluid becomes the interstitial fluid that bathes tissues and helps to deliver nutrients and oxygen to cells. In addition to returning lymph to circulation, lymphatic structures also filter blood of microorganisms, such as bacteria and viruses. Lymphatic structures also remove cellular debris, cancerous cells, and waste from the blood. Once filtered, the blood is returned to the circulatory system.
What is the function of lymphatic structures?
In addition to returning lymph to circulation, lymphatic structures also filter blood of microorganisms , such as bacteria and viruses. Lymphatic structures also remove cellular debris, cancerous cells, and waste from the blood. Once filtered, the blood is returned to the circulatory system.
What is the function of blood?
Blood delivers nutrients to cells and removes wastes that are produced during cellular processes, such as cellular respiration. Blood is composed of red blood cells, white blood cells, platelets, and plasma. Red blood cells contain enormous amounts of a protein called hemoglobin. This iron-containing molecule binds oxygen as oxygen molecules enter blood vessels in the lungs and transports them to various parts of the body. After depositing oxygen to tissue and cells, red blood cells pick up carbon dioxide (CO 2) for transportation to the lungs where CO 2 is expelled from the body.
What is the process of the heart?
The heart is the organ that supplies blood and oxygen to all parts of the body. This amazing muscle produce s electrical impulses through a process called cardiac conduction. These impulses cause the heart to contract and then relax, producing what is known as a heart beat. The beating of the heart drives the cardiac cycle which pumps blood to cells and tissues of the body.
How does blood travel through the body?
Blood vessels are intricate networks of hollow tubes that transport blood throughout the entire body. Blood travels from the heart via arteries to smaller arterioles, then to capillaries or sinusoids, to venules, to veins and back to the heart. Through the process of microcirculation, substances such as oxygen, carbon dioxide, nutrients, and wastes are exchanged between the blood and the fluid that surrounds cells.
What organs help the heart?
The Lungs. Your lungs aren't technically a part of circulatory system organs, but they really help make it possible for your heart to function correctly. Your lungs provide oxygen for your body. The lungs send oxygen-rich blood to the left side of your heart and your heart then uses blood vessels and arteries to transfer it to the rest of your body.
What are some interesting facts about the circulatory system?
Amazing Facts About Circulatory System 1 Capillaries are quite tiny and are about 8 microns in diameter, and quite interestingly, red blood cells are almost of the same size as the capillaries. 2 With an increase in body size, the heart rate comes down. A blue whale heart is bigger than a compact car, but it beats only five times a minute. However, a shrew has a heart rate of 1000 beats per minute. 3 People have been studying the circulatory system since the 16 th century B.C. 4 A Greek physician came up with an erratic model of the circulatory system that was followed for 1500 years. 5 Other cells in your body have nuclei, but your red blood cells are different, because they contain no nuclei and that's why they can carry more oxygen. 6 There is no such thing as "broken heart" after an emotional setback. All you experience is "broken heart syndrome" characterized by a sudden, temporary weakening of the muscle of your heart.
How big are the capillaries in the circulatory system?
Capillaries are quite tiny and are about 8 microns in diameter, and quite interestingly, red blood cells are almost of the same size as the capillaries. With an increase in body size, the heart rate comes down.
What are the three main types of blood vessels?
There are three basic types of blood vessels, including capillaries, arteries and veins. Arteries take oxygen-rich blood away from your heart. Veins take blood back toward your heart. Capillaries are very tiny blood vessels that form a connection between arteries and veins.
How many chambers does the heart have?
It consists of four hollow chambers – two ventricles and two atria. All four chambers work quite like pumps and push blood throughout your body. The blood that moves towards the heart enters it through the atria and then goes out to your body through the ventricles.
Why does the heart pump blood?
Your heart pumps blood throughout your body and travels through thousands of miles, mainly because it has to move through the network of blood vessels within your body. Your blood is an amazing substance that carries water, nutrients, waste products and oxygen to and from your body cells. A young person will have up ...
Which blood cells transport oxygen to the rest of the body?
Red Blood Cells. These cells take oxygen from your lungs and transport it to the rest of your body cells. After delivering the oxygen, it gathers up the carbon dioxide and delivers it back to your lungs. White Blood Cells. These blood cells play a role in fighting off germs and protect you from diseases.
What is the cardiovascular system?
The cardiovascular system consists of the heart, blood vessels, and the approximately 5 liters of blood that the blood vessels transport. Responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body, the cardiovascular system is powered by the body’s hardest-working organ — the heart, ...
Where is the heart located in the cardiovascular system?
Cardiovascular System Anatomy. The Heart. The heartis a muscular pumping organ located medial to the lungs along the body’s midline in the thoracic region. The bottom tip of the heart, known as its apex, is turned to the left, so that about 2/3 of the heart is located on the body’s left side with the other 1/3 on right.
How does blood flow affect blood pressure?
The regulation of blood flow also affects blood pressure, as smaller arteries give blood less area to flow through and therefore increases the pressure of the blood on arterial walls. Arterioles are narrower arteries that branch off from the ends of arteries and carry blood to capillaries.
What is the layer of blood that lines the entire circulatory system?
All blood vesselsare lined with a thin layer of simple squamous epithelium known as the endothelium that keeps blood cells inside of the blood vessels and prevents clots from forming. The endothelium lines the entire circulatory system, all the way to the interior of the heart, where it is called the endocardium.
Which organs pick up blood from many capillaries and deposit it into larger veins for transport back to the heart
Venules pick up blood from many capillaries and deposit it into larger veins for transport back to the heart. Coronary Circulation. The heart has its own set of blood vessels that provide the myocardium with the oxygen and nutrients necessary to pump blood throughout the body.
What is the hollow area of a blood vessel?
The size of blood vessels corresponds with the amount of blood that passes through the vessel. All blood vessels contain a hollow area called the lumen through which blood is able to flow. Around the lumen is the wall of the vessel, which may be thin in the case of capillaries or very thick in the case of arteries.
How does the cardiovascular system affect blood pressure?
Several functions of the cardiovascular system can control blood pressure. Certain hormones along with autonomic nerve signals from the brain affect the rate and strength of heart contractions. Greater contractile force and heart rate lead to an increase in blood pressure. Blood vessels can also affect blood pressure.
