Question

explain the structure of heart and explain briefly?​

Answer 1

The heart is divided into four chambers consisting of two atria and two ventricles; the atria receive blood, while the ventricles pump blood. The right atrium receives blood from the superior and inferior vena cavas and the coronary sinus; blood then moves to the right ventricle where it is pumped to the lungs.The valves in the heart
are required to prevent backflow of the blood.The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.The right ventricle pumps the oxygen-poor blood to the lungs.The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.

Answer 2

Hello friend

. Heart is a muscular organ which is as big as our fist

. Heart transports both oxygen and CO2 all o'er the body this it has

four chambers

. Those were the right atrium and right ventricle left atrium left ventricle

. Deoxygenated blood comes to heart through venacava to right atrium as it is relaxed and when it contrast it moves to right ventricle as it relaxes then with pressure the blood is send to lungs for purification

. Oxygenated blood enters left atrium then to ventricle and is pumped with pressure throughout body to all parts of the body
