- discuss how mild fevers are beneficial Fevers help the body fight infection by interfer- ing with the growth and replication of pathogens. Fevers also causes lysosomes, an organelle inside cells, to break down. The lysosomes release diges- tive enzymes that lyse cells infected by a virus. In addition, fevers can promote the activity of white blood cells. Mild fevers of short duration can aide in recovery.

Immunosuppressant drugs suppress the immune system. Suppressing the immune system is necessary so that the body does not reject the organ transplant or tissue graft. While taking these immunosuppressant drugs the patient is more susceptible to disease

- Describe the structure of a lymph node
A lymph node is encapsulated in a fibrous connec- tive tissue with many incoming and fewer outgoing lymphatic vessels. Incoming vessels (atterent ves- sels) flow through a network of sinuses that con- tain cells. The lymph then flows out of the lymph node through the etterent vessel. The interior of the

- Describe the function of eosinophils. Eosinophils respond to allergic reactions and par- asitic infections. As a granulocyte, eosinophils are also capable of phagocytosis.
- Basophils release histamine and heparin
- Describe the structure of a B cell and how it becomes activated
Each B cell is genetically programmed to produce a glycoprotein receptor as part of its cell coat. Each receptor binds with a specific type of antigen. B cells become activated when an antigen binds with its receptor. Once activated it is now called a plasma cell.
- Describe the function of Killer T cells. Recognize and destroy invading cells containing foreign antigens by releasing cytokines and en- zymes to lyse the cells.
- Describe the function of helper T cells. Secrete substances that activate or enhance im- mune response. B cells require interactions with helper T cells before beginning rapid division
- Describe the function of natural killer cells
Seek out abnormal body cells and destroy them. Highly ettective against tumor cells.
- How does RA impact the body? Rheumatoid arthritis, T cells produce interleukins which cause inflammation inside the joints system- ically
- How does MS impact the body? Antibodies attack the or prevent the formation of the myelin sheath around nerve cells, resulting in muscular weakness.
- How does lymphedema impact the body?
