Heart attack
A heart attack happens when a part of the heart muscle does not receive enough blood. This can occur due to a blockage, a tear in an artery around the heart, or if the heart requires more oxygen than is available.
Stroke
A stroke is a medical condition in which the blood supply to a part of the brain becomes cut off. This lack of blood supply triggers the death of brain cells.
Heart failure
Heart failure occurs when the heart is unable to pump enough blood to satisfy the body’s needs.
Arrhythmia
An arrhythmia is an abnormal heart rhythm. It may present as a heartbeat that is too quick, too slow, or has a distinctive pattern. Symptoms may include:

How does the cardiovascular system maintain homeostasis?
The vital role of the cardiovascular system in maintaining homeostasis depends on the continuous and controlled movement of blood through the thousands of miles of capillaries that permeate every tissue and reach every cell in the body. It is in the microscopic capillaries that blood performs its ultimate transport function.
Which organ is the major organ of the cardiovascular system?
The major organ of the cardiovascular system is the heart. The heart is a muscular organ in the center of your chest that contracts about 60-80 times a minute to pump blood throughout your body.
What is the cardiovascular system?
The cardiovascular system circulates blood throughout your body to transport oxygen and carbon dioxide, nutrients, hormones, and cells to all your organs and tissues. 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 ...
Which organ is responsible for pumping blood through the body?
The heart is a muscular organ in the center of your chest that contracts about 60-80 times a minute to pump blood throughout your body. The atrium is one of two small chambers in the heart that collect blood returning to the heart from the systemic or pulmonary circulation.
What are the main parts of the circulatory system?
It is made up of three main parts: the heart, pulmonary circulation, and systemic circulation.
What is the heart muscle made of?
It is made of many layers of a special type of muscle tissue called cardiac muscle , which is striated, involuntary muscle tissue. Remember that myocardium, muscle, and middle all start with the letter M, so when you think about the muscle in the middle of the heart wall, you will know that it is called the myocardium.
Where does deoxygenated blood go?
After passing through the right atrium and ventricle, the blood is pumped into the pulmonary artery, which carries deoxygenated blood to the lungs.
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 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.
Which organ is responsible for transporting oxygen, nutrients, hormones, and cellular waste products throughout the body?
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, which is only about the size of a closed fist. Even at rest, the average heart easily pumps over 5 liters of blood throughout the body every minute.
Where is the heart located?
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.
Which chambers of the heart support the pulmonary circulation loop?
The pumping chambers of the heart that support the pulmonary circulation loop are the right atrium and right ventricle.
What are the three main types of blood vessels?
There are three major types of blood vessels: arteries, capillaries and veins . Blood vessels are often named after either the region of the body through which they carry blood or for nearby structures. For example, the brachiocephalic arterycarries blood into the brachial (arm) and cephalic (head) regions.
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.
Where is the heart located?
The Heart. Located slightly to the left of the middle of your chest, the heart is made of strong muscle tissue and is protected by your rib cage. Even though it is no larger than the size of your fist, it plays a vitally important role in your body. It consists of four hollow chambers – two ventricles and two atria.
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.
What is the heart made of?
Located slightly to the left of the middle of your chest, the heart is made of strong muscle tissue and is protected by your rib cage. Even though it is no larger than the size of your fist, it plays a vitally important role in your body. 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.
How many chambers does the heart have?

What is the hollow area of the blood vessel called?
Blood vessels have a hollow area that allows for easy flow of blood – it's called lumen.
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.
What are the capillaries?
Capillaries are very tiny blood vessels that form a connection between arteries and veins. The capillary walls facilitate the transfer of oxygen, nutrients and wastes in and out of your body. 3. The Lungs.
