Question

explain circulatory system in human beings

Answer 1

blood is the fluid connective tissue which transports food and oxygen to cells and also removes the waste. so it is being circulated in the body by circulatory system.
at first the right auricle receives deoxygenerated blood from throughout the body by the help of venacava.this then travels to right ventricle by tricuspid valve. then the blood through pulmonary artery travels to the lungs where the CO2 is released and O2 is mixed with blood. this blood through pulmonary artery travels to left auricles and them from bicuspid valve to left ventricle. from there through aorta, it gets distributed in the whole body cells for respiration. thus this process continues.

Answer 2

Here is your answer!
The circulatory system is a system that transports nutrients and collects waste materials for disposal in the human body. The circulatory system consists of the central organs like, hearth, blood vessels and blood. The heart carries deoxygenated blood from the upper and lower parts of the body and supply that blood to the right auricle of the heart. Then his auricle passes the blood to the right ventricle and further it passes the blood into arteries, which pumps the blood into lungs. It also then passes to the left atrium of the heart.
