Current Question (ID: 14484)

Question:
The given figure shows schematic plan of blood circulation in humans with labels A to D. Identify the labels along with their functions and select the correct option.
Options:
  • 1. C - Vena Cava - takes blood from body parts to right atrium, PCO₂ = 45 mm Hg
  • 2. D - Dorsal aorta - takes blood from heart to body parts, PO₂ = 95 mm Hg
  • 3. A - Pulmonary vein - takes impure blood from body parts to heart, PO₂ = 60 mm Hg
  • 4. B - Pulmonary artery - takes blood from heart to lungs, PO₂ = 90 mm Hg
Solution:
In the given figure: A is pulmonary vein which brings pure blood from lungs to left atrium, B is dorsal aorta which carries blood from heart to body parts, C is vena cava which carries impure blood from body parts to right atrium, and D is pulmonary artery which takes impure blood from heart to lungs.
