Explain the process of oxination of blood in human body through a flow chart
Answers
ahoy.
the oxygenated blood enters from the four pulmonary veins into the left atrium and then it is moved to the left ventricle by the atrial contraction and opening of mitral valves the left ventricle then contracts and the semi lunar valves of the aaorta open and the blood is supplied to organs which require oxygen.
the deoxygenated blood from organs travels through inferior and superior vena cava and ends up coming into the right atrium which then contracts the blood moves into the right ventricle as the right auriculo-ventricular valves open and it is then forced to the pulmonary arch followed by opening of semi lunar valves.
the pulmonary arch divides into two and each one takes blood to two lungs for oxygenation and then this oxygenated comes back to heart by the pulmonary vein and the cycle goes on.
peace.
