NEET PG DENTAL EXAM

Detailed explanation-1: -The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen. From the small intestine, the blood gathers food nutrients and delivers them to every cell.

Detailed explanation-2: -The circulatory system, which is made up of the heart and blood vessels, supports the respiratory system by bringing blood to and from the lungs. The circulatory system helps deliver nutrients and oxygen from the lungs to tissues and organs throughout the body. It also helps remove carbon dioxide and waste products.

Detailed explanation-3: -How does the circulatory system work? Blood that is low in oxygen collects in your heart’s right atrium, one of the heart’s 4 chambers. It moves into the right ventricle, which pumps this blood to your lungs where your red blood cells pick up oxygen and get rid of carbon dioxide. You exhale the carbon dioxide.
