The figure given below shows a schematic plan of blood circulation in humans with labels (i) to (iv). Identify the correct label with its functions?

(a) (i) Pulmonary vein – takes impure blood from body part.

(b) (ii) Pulmonary artery – takes blood from lung to heart.

(c) (iii) Aorta – takes blood from heart to body parts.

(d) (iv) Vena cava takes – blood from body parts to right auricle.

Ans. (d) (iv) Vena cava takes – blood from body
parts to right auricle.

Explanation:(i) It is pulmonary vein which carries ox￾ygenated blood from lungs and pours
into left atrium.

(ii) It is aorta which carries oxygenated
blood from the left ventricle of the
heart to various parts of the body.

(iii) It is pulmonary artery carries deoxy￾genated blood from the right ventricle
to the lungs.

(iv) It is vena cava which carries deoxy￾genated blood from various parts of
the body and pours it into right atri￾um.

Therefore, the correct option is (d), as the parts
(ii) and (iii) have been marked wrong, whereas
the function of part (i) is wrongly mentioned.
