Question

Give three kinds of blood vessels present in human circulatory system and
write their functions.

Answer 1

Answer:

Arteries. They carry oxygen-rich blood away from the heart to all of the body's tissues. They branch into smaller and smaller arteries as they carry blood farther from the heart and into organs.

Capillaries. These small blood vessels connect the arteries and the veins. Their thin walls allow oxygen, nutrients, carbon dioxide, and other waste to pass to and from cells.

Veins. These are blood vessels that take blood back to the heart. They get become larger as they get closer to the heart. The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.
