What is the main function of veins?
Answer and explanation
Correct answer: To bring blood towards the heart
Veins are blood vessels whose main function is to return blood from body tissues to the heart. They generally carry deoxygenated blood, except for pulmonary veins, which bring oxygenated blood from the lungs to the left atrium. Veins usually have thinner walls and valves that help prevent backflow, especially in the limbs. Arteries carry blood away, while oxygen production and food breakdown are different processes; therefore A is correct.
