Explain the function of Heart with diagram .

Answer 1

FUNCTION OF HEART

• Deoxygenated blood is received by the heart from the body through superior and inferior vena cava. The superior vana-cava carries deoxygenated blood from the upper region and inferior vena-cava from the lower region of the body.
• The blood from both the vena-cava is received by the right atrium. Right atrium also receives blood from coronary sinuses. This blood (deoxygenated) flows into the right ventrical. The opening between the right aurical and ventrical is guarded by a tricuspid valve. Now blood from right ventricle is pumped into the lungs(for oxygenation) through the pulmonary artery.
• After the blood is oxygenated in the lungs, it is again received by the heart in the left atrium through the pulmonary vein. Now the blood from left atrium flows into the left ventricle. The opening of the left atrium and ventricle is guarded by the bicuspid valve.
• The left ventricle is now containing the oxygenated blood which is pumped through the aorta and reaches all the organs through arteries.
