| Term | Definition |
|---|---|
| Pathogen | any microbe that can cause disease |

| Plasma | the liquid part of the blood |
| Plasma cells | large cell factories that make antibodies quickly |
| Platelets | a minute disk like cytoplasmic body found in the blood plasma of mammals that functions to promote blood clotting. |
| Protein | molecules made up of amino acid; proteins are necessary in all living matter and are essential compound of the immune system |
| Protozoa | extremely small creatures that mostly live in water |
| Pulmonary artery | splits into two branches that carry blood from the right ventricle of the heart to the lungs |

| Symptom | an indication of a disease that the sufferer notices (headaches, aching joints, sore throat, runny nose) |
| T-cells | lymphocytes or white blood cells that stimulate the immune response. The HIV virus attacks and destroys t-cells. |
| Vaccine | a man-made substance that stimulates antibody production in the body to produce immunity against a specific disease/illness |
| Veins | blood vessels that carry blood to the heart |
| Virus | microbes that need a host to survive, main goal is to reproduce and spread. causes disease; too tiny to be seen with an ordinary microscope; made of proteins and genetic material. does not need nutrients to survive |
| White blood cells | any various blood cells that have a nucleus and cytoplasm, which separate into a thin white layer when whole blood is centrifuged; infection fighting cells |
