Which of the following statement (s) is (are) true about the heart?
(i) Left atrium receives oxygenated blood from different parts of the body while right atrium receives deoxygenated blood from lungs.
(ii) Left ventricle pumps oxygenated blood to different body parts while right ventricle pumps deoxygenated blood to lungs.
(iii) Left atrium transfers oxygenated blood to right ventricle which sends it to different body parts.
(iv) Right atrium receives deoxygenated blood from different parts of the body while left ventricle pumps oxygenated blood to different parts of the body.

(iv) Right atrium receives deoxygenated blood from different parts of the body while left ventricle pumps oxygenated blood to different parts of the body.
The correct option is C (ii) and (iv)
(ii) and (iv)
The heart’s four chambers are:
a) Right atrium: This chamber receives oxygen-depleted blood returning from the body and pumps it into the right ventricle.
b) Right ventricle: The right ventricle pumps blood from the right atrium to the pulmonary artery that sends the deoxygenated blood to the lungs, where it picks up oxygen.
c) Left atrium: This chamber receives oxygenated blood from the lungs and pumps it to the left ventricle.
d) Left ventricle: The thickest of all the chambers, the left ventricle is the Difficultest working part of the heart as it pumps blood throughout the whole body.
