which are the kinds of blood vessels. write their function
Answers
Answer:
The blood carries oxygen, nutrients, and wastes that need to move around the body. There are three kinds of blood vessels: arteries, veins, and capillaries. Arteries have a thicker wall and a smaller inside hole than veins.
Explanation:
Arteries. Arteries carry oxygen-rich blood away from the heart to all of the body's tissues. They branch several times, becoming smaller and smaller as they carry blood farther from the heart and into organs.
Capillaries. These are small, thin blood vessels that connect the arteries and the veins. Their thin walls allow oxygen, nutrients, carbon dioxide, and other waste products to pass to and from cells.
Veins. These are blood vessels that take blood back to the heart; this blood contains less oxygen and is rich in waste products that are to be excreted or removed from the body. Veins 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.
