CardiovascularWhat Is the Meaning of Cardiovascular?

The cardiovascular system, also referred to as the circulatory system, includes the heart and blood vessels. The heart pumps the blood throughout the body. To do this effectively, this organ has four separate chambers – two ventricles and two atria. Blood low in oxygen enters the heart through the right atrium, passes through to the right ventricle, and then goes through the pulmonary artery to the lungs, where it receives oxygen. Then this blood passes into the left atrium, passes into the right atrium, and leaves through the body's largest artery, the aorta, and gets pumped to the rest of the body.

Cardiovascular Blood Vessels

Blood vessels themselves also get divided into three categories. Arteries pump blood from the heart to other organs throughout the body. Normally this is oxygenated blood, except in the case of the pulmonary arteries mentioned above. But all arteries carry blood away from the heart. Veins do just the opposite – they take blood from the body to the heart. Again, normally this blood is low in oxygen, except for the pulmonary veins that take blood from the lungs to the heart. The third type of blood vessel is a capillary. These are the smallest and thinnest of the blood vessels, and the miniscule walls allow molecules such as water and oxygen to pass through them into the body's tissues.


Cardiovascular Careers and Training

This intricate system must work properly to keep a human being alive. A cardiovascular technician assists a doctor in identifying problems with either the heart or blood vessels. Various procedures must be used to diagnose diseases, all of which require formal training. A cardiovascular surgeon specializes in the treatment of these diseases through surgical procedures.


Overall, cardiology offers plenty of career prospects and can be a fascinating field to study.
