Answer 9

The largest artery in the body

Question 10

What are Arterioles?

Answer 10

Small arteries that deliver blood to capillaries

Question 11

What are Capillaries?

Answer 11

Tiny, thin-walled blood vessels that connect the smaller arteries to venues; Brings nutrients to cells and carry away waste materials

Question 12

What are Venules?

Answer 12

Small vessels that connect the capillaries to the veins; Collect blood from the capillaries and drain it into the veins

Question 13

What are Veins?

Answer 13

Thin-walled blood vessels that are less elastic than arteries; Contain cuplike valves that keep blood flowing in one direction to the heart and prevent blood from flowing backward; Carry blood containing waste products back to heart and lungs for cleaning and to pick up oxygen
