Document Summary

Inflammation: complement, third - specific, cell-mediated, humoral. Leukocytes: 5 types of immune cells (leukocytes), neutrophil, lymphocyte, monocyte, eosinophil, basophil. Specific (acquired: platelets aid clotting system (prevent clots) Innate (1st & 2nd) immune response: phagocytosis: phagocytic cell engulfs bacteria & encloses it in a vesicle; then an enzyme containing bubble fuses with this vesicle to destroy the bacteria inside it, & then releases the remnants. Acquired (3rd) immune response: foreign body is presented to the [3rd] immune system in 2 ways, by immune (antigen presenting) cells; so other cells can recognize it, by infected cells (with viral proteins on its surface) Figure: there is not much difference at the start of training (stretchers vs. exercisers), but later on it shows that regular exercise (compared to stretching) will prevent colds. Figure: controls (runners who did not compete) showed lower upper. Figure: cells circulating the body increases: after exercise, number of lymphocytes decreases and neutrophils increases, when exercising, the number of immune.
