Which Organ System Is The Heart In – Your circulatory system, also called the cardiovascular system or circulatory system, carries oxygen, nutrients, and hormones to your body’s cells to use for energy, growth, and recovery. Your circulatory system also removes carbon dioxide and other waste products that your cells don’t need.
These key parts of your circulatory system keep blood flowing to every cell in your body so you can survive:

Which Organ System Is The Heart In
Low-oxygen blood collects in the right atrium of your heart, one of the heart’s 4 chambers. It moves into the right ventricle, which pumps this blood into your lungs where your red blood cells pick up oxygen and get rid of carbon dioxide. Then you exhale the carbon dioxide.
Heart Block: Types, Causes, Symptoms, And Risk Factors
Oxygen-rich blood returns to the left atrium of your heart, then to the left ventricle. The left ventricle pumps oxygen-rich blood through your aorta, into your arteries, then to all parts of your body. Along the way, the blood picks up nutrients from your small intestine.
As it enters the capillaries, your blood comes into contact with tissues and cells. It delivers oxygen and nutrients and removes carbon dioxide and waste. Now that it’s low on oxygen, the blood travels through the veins to return to the right atrium of your heart, where the cycle begins again.
Most CVD occurs when fatty substances, called plaque or atheroma, build up in the lining of blood vessels. Because of this, blood vessels become narrow over time. Then less blood can pass. This process is called atherosclerosis.
Atherosclerosis can cause coronary heart disease and ischemic heart disease. Reduced blood supply means less oxygen and nutrients available to the heart muscle. This can cause angina or a heart attack, which requires immediate medical attention. The most common symptom of a heart attack or angina is chest pain.

When the blood supply to a part of the brain is cut off due to a blocked or ruptured artery, it results in a stroke. A stroke is also an emergency and will need immediate medical treatment.
When your heart pumps blood into your arteries, the blood pushes against the walls of the arteries. This is what gives you a blood pressure reading. Blood pressure is measured in units called ‘millimeters of mercury’ (written as mmHg). Most doctors consider healthy blood pressure to be higher than 90/60 mmHg and lower than 140/90 mmHg.
High blood pressure, also known as hypertension, can increase the risk of cardiovascular disease. It is the most common health problem of the circulatory system.
Low blood pressure, also known as hypotension, is a sign of good health for some people, but can be a problem for others. Symptoms of low blood pressure include dizziness or fainting.
Human Body’s Organ Systems And Their Function
The best way to find out how healthy your circulatory system is is to see your doctor for a heart health check. Heart health screenings should take about 20 minutes and are covered by Medicare if you qualify.
The earlier cardiovascular disease is detected, the sooner it can be treated and controlled. If you have high blood pressure, it is especially important to have regular heart health checks with your doctor.
Low blood pressure is only a problem if it has negative effects on how your body works or how you feel. See your doctor if you have symptoms, for example, if you feel:
There are some risk factors that cannot be changed when it comes to cardiovascular health, such as aging, family history, or ethnicity. However, you can improve heart health and reduce the chance of cardiovascular disease.

Organ System On A Female Torso Poster Print By Spencer Sutton/science Source
In humans, the heart is located between the two lungs and a little to the left of the center, behind the sternum. It rests on the diaphragm, the muscular partition between the chest and the abdominal cavity.
The heart consists of several layers of solid muscle wall, the myocardium. A thin layer of tissue, the pericardium, covers the outside, and another layer, the endocardium, lines the inside.
