Explain the heart function and qork?
Verified Answer
Explain the heart function and qork?
Function of heart:
Our Heart is about the size of a fist divided into four chambers namely two ventricles and two atria, as discussed above. There are one ventricle and one atrium on the left side and the other atrium and ventricle towards the right side. The ventricles are the chambers that pump blood and atria are the chambers that receive blood. The deoxygenated blood received to right atrium from:
The superior vena cava is released into the veins of the upper arms and organs.
The inferior vena cava that leaves blood from the veins of legs and lower organs.
The coronary sinus, that leaves deoxygenated blood from the heart.
The right ventricle pumps the blood to the lungs for re-oxygenation when it gets filled up by the pulmonary arteries. The right semilunar valves close and prevents the blood from the pulmonary veins after blood passes through the pulmonary arteries. Then the oxygenated blood is received by the left atrium from the lungs via pulmonary veins.
Working of the heart:
• The heart of the human works like a pump.
• Pure oxygenated blood enters the left auricle from lungs through pulmonary veins.
• The deoxygenated blood from various part of the body enters right auricle through veins and capillaries.
• The two auricles contract simultaneously so the oxygenated blood from left auricle to left ventricle and deoxygenated blood from right auricle is pumped into right ventricle.
• Now both the ventricles contract simultaneously so the pressure is created on the blood and the valves between auricle and ventricle close and the blood does not go back into auricle.
• Due to this pressure, aorta valve opens and the blood comes in aorta, from here, blood is sent to different parts of the body with the help of various arteries.
• By the contraction of right ventricle, blood reaches the lungs through pulmonary arteries where it gets reoxygenated.
