Also known as: Circulatory system, Vascular system or Cardiovascular system
- The right atrium receives oxygen-poor blood from the body. That blood then flows into the right ventricle, which pumps it to the lungs.
- The left atrium receives oxygen-rich blood from the lungs. From there, the blood flows into the left ventricle, which pumps blood out of the heart to the rest of the body.

The body's cardiovascular, or circulatory system, is made of the heart, blood, and blood vessels (arteries and veins).
Heart and vascular services refers to the branch of medicine that focuses on the cardiovascular system.
The heart's main job is to pump oxygen-rich blood to the body after it pumps oxygen-poor blood to the lungs. It normally does this 60 to 100 times a minute, 24 hours a day.
The heart is made of four chambers:
Together, the arteries and veins are referred to as the vascular system. In general, arteries carry blood away from the heart and veins carry blood back to the heart.
The cardiovascular system delivers oxygen, nutrients, hormones, and other important substances to cells and organs in the body. It plays an important role in helping the body meet the demands of activity, exercise, and stress. It also helps maintain body temperature, among other things.
Cardiovascular medicine refers to the branch of health care that specializes in the treatment of diseases or conditions dealing with the heart and vascular systems.
Common disorders include:
Physicians involved in the treatment of circulatory or vascular diseases include:
Other health care providers who are involved in the treatment of circulatory or vascular diseases include:
Imaging tests that may be done to diagnose, monitor or treat diseases of the circulatory and vascular system include:
SURGERIES AND INTERVENTIONS
Less invasive procedures may be done to diagnose, monitor or treat diseases of the heart and vascular system.
In most of these types of procedures, a catheter is inserted through the skin into a large blood vessel. In most cases, such procedures do not need general anesthesia. Patients often do not need to stay in the hospital overnight. They recover in 1 to 3 days and can most often return to their normal activities within a week.
Such procedures include:
Heart surgery may be needed to treat certain heart or blood vessel problems. This may include:
Vascular surgery refers to surgical procedures that are used to treat or diagnose problems in a blood vessel, such as a blockage or rupture. Such procedures include:
Procedures may also be used to treat arteries that supply the brain, kidneys, intestines, arms and legs.
CARDIOVASCULAR PREVENTION AND REHABILITATION
Cardiac rehabilitation is therapy used to prevent heart disease from getting worse. It is usually recommended after major heart-related events such as a heart attack or cardiac surgery. It may include:
