answer
Both the lymphatic and the immune system
question
Functions of the lymphatic system:
answer
1. reduces tissue edema by removing fluid from capillary beds. 2. returns the proteins from the fluids to the blood. 3. traps and filters cellular debris, such as cancer cells and microbes, with the help of cells called macrophages. 4. recycles body fluid to various parts of the body. 5. circulates lymphocytes to assist with the immune response. 6. moves fats from the gastrointestinal (GI) tract to the blood.
question
Functions of the immune system:
answer
1. protects the body against foreign body invasion. 2. normal function, it coordinates activities in the blood, body tissues, and the lymphatic system to protect the body from foreign body invasion. 3. fights off infections and protects against future infections by producing a variety of immune responses. 4. produces antibodies (immunoglobulins).
question
List the major locations of lymph nodes:

answer
Lymphatic system
question
Lymph
answer
Fluid that contains white blood cells and other substances and flows in the lymphatic vessels.
question
Lymphatic pathways
answer
The vessels that transport lymph (the fluid of the lymphatic system) around the body. The smallest parts of these pathways are the microscopic capillaries located in the capillary beds of the body. The capillary beds are thin-walled vessels that receive fluid and debris from the bloodstream. Once inside the beds, the fluid is known as lymph
question
Lymphatic Vessels
answer
The lymph travels throughout the lymphatic vessels in one direction only—back toward the heart. Lymphatic vessels contain valves that prevent backflow of lymph. As the vessels approach the heart, they carry more fluid and are larger in size.
question
Lymph node
answer
Specialized organ that filters harmful substances from the tissues and assists in the immune response. The lymph passes through many lymph nodes for filtering so that it is ready for transferring back to the vascular system. Lymph nodes are located throughout the body except in the central nervous system. They are quite numerous near the joints of the body. The major groups of lymph nodes are located in the throat (the tonsils and adenoids are actually lymph tissue), neck, axilla (armpit), mediastinum, and groin.
