Q. Which of the following match correctly?

1. Inferior vena cava - Receives deoxygenated blood from the head and body.
2. Superior vena cava - Receives deoxygenated blood from the lower body and organs.
3. Pulmonary artery - Carries deoxygenated blood to the lungs.
4. Hepatic artery - Carries deoxygenated blood to the gut.

2. break up into capillaries which reunite to form a vein
3. carry blood from one visceral organ to another visceral organ
4. Supply oxygenated blood to different organs
