4

What are the 3 primary functions of the lymphatic system?

absorb fats from the small intestine, remove waste from tissues, provide aid to the immune system

5

small finger-like projections that line the small intestine

villi

6

transports lymph from tissues throughout the body and returns the fluid to the venous circulation

lymphatic circulation

7

another name for the lymphatic system

secondary circulatory system

8

How are the cardiovascular system and lymphatic system different?

lymph flows in one direction, lymph flows in a closed system, lymph does not have a pump, lymph is clear, lymph is filtered by nodes

9

plasma from arterial blood that flows out of capillaries and into the space between the cells

interstitial fluid

10

microscopic tubes located near the surface of the body that lymph travels through

lymphatic capillaries
