Which of the following statement(s) is(are) true about 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 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
Deoxygenated blood from different parts of the body enters the heart through the right atrium. It is then pumped into the right ventricle. The right ventricle sends it to the longs. In the lungs, blood is oxygenated. The lungs send it back to the left atrium. The left atrium pumps the oxygenated blood into the left ventricle. The left ventricle sends this blood to the rest of the body.
NOTE: Left atrium, left ventricle, right atrium and right ventricle are the four chambers of human heart.
