Anatomy and Physiology Topic 14: Lymphatic System

Lymphatic System is

• the immune system

• the circulatory system

• cells and biochemicals that travel in lymphatic vessels

• A combination of immune and circulatory systems

Lymphatic Systems Functions are to

• Transport fluid away from interstitial spaces

• Transports blood away from blood vessels

• Transports blood cells

• Transports nutrients to tissues

Another major function of the lymphatic system is

• Attack the body's cells when they don't "act right"

• Attack foreign particles

• Attack the blood cells

• Attack the white blood cells to weaken the immune system

Lymphatic capillaries run parallel to networks of blood capillaries

• True

• False

Once inside the lymphatic vessels the fluid is called blood.

• True

• False

Lymph Nodes are

• Mass of tissue that is located along the blood vessels

• Mass of tissue that is located along the thoracic cavity

• Mass of lymphoid tissue located along the course of a lymphatic vessel

• Mass of immune tissue that attacks foreign tissue

What are the functions of lymph

• Transport hydrostatic pressure

• Returns fluid back to the bloodstream and transports foreign particles to lymph nodes

• Protect agains your body's cells by transporting blood cells

• Produce fluid in between the tissue.

All of the following are ways that can increase the flow of lymph through the lymphatic vessels except.

• Breathing

• Smooth Muscle Contraction

• Skeletal Muscle Contraction

• Lymphatic valves

• None, all of the above increase flow of lymph

Edema is

• Pain

• Swelling

• Redness

• Loss of function

Lymph nodes are absent in the central nervous system.

• True

• False
