| HIV/AIDS | Human Immunodieficiency Deficiency Virus; a virus that attacks the immune system and cause the disease AIDS, or Acquired Immune Deficiency Syndrome, is the disease resulting from HIV infection. Its effects include the general failure of the immune system, |
| Helper T cells | T cells that help control immune system function be sending other immune units to fight the invader |
| Immune system | the units of the body (organs, tissues, cells, and cell products such as antibodies) that work together to fight disease |
| Immunodeficiency | the loss of certain immune system functions and/or structures |
| Inferior vena cava | lower blood vessel that carries used blood into the right side of the heart. |
| Inflammation response | the body’s response to an injury indicated by a fever and/or swelling, redness, and pain of the injured areas due to increased blood flow to the area |
