difference between aorta and valves
Answers
The walls of the ventricles are thicker, while that of the atria are thinner. They however contain valves to pump the blood in and out of the heart. The walls of the heart, including the atria and the ventricles are functional in ensuring effective working of the circulatory system. The walls of the heart are made of 3 layers of tissues ‘“ myocardium, endocardium and epicardium. The function of the right atrium is to receive deoxygenated blood from the veins. Its oxygen has been given to the tissues in return collecting CO2 and tissue waste materials. Deoxygenated blood is transferred from the upper part of the body to the atrium by the SVC or superior vena cava. The IVC or inferior vena cava brings deoxygenated blood from the lower part of the body into the atrium.
