Distinguish between the arteries and veins on the basis of the direction of the flow of blood and the type of blood they carry.
Answers
Answer:
Arteries and veins (also called blood vessels) are tubes of muscle that your blood flows through. Arteries carry blood away from the heart to the rest of the body. Veins push blood back to your heart. You have a complex system of connecting veins and arteries throughout your body.
Explanation:
Veins and arteries play important roles in your breathing ( respiratory) and blood flow (circulatory) systems. Understanding these systems can help you understand how your veins and arteries work.When you breathe, you inhale oxygen from the air. Your body needs oxygen for chemical reactions that produce energy and keep you alive. Carbon dioxide is a waste product of these chemical reactions. Your body needs to get rid of the carbon dioxide, or serious health problems can happen.
