Document Summary
In the bone marrow; but in children in the yolk sac then liver then bone marrow. Tissue, blood, lymph, peripheral organs (lymphnodes/tonsils/adrenoid/spleen), central lymphoid organs (thymus and bone marrow) Spongy connective tissue of the long bones contains immune cells, red blood cells, fat and connective tissue. Circulation occurs, blood lets fluid seep out of the capillaries into tissues gathers with antigens. Antigens/fluid from lymphatic tissues put into lymphatic vesicles and brought to peripheral organs for antigen presentation then put back into the circulatory system. In the buffer pmn polymorphonuclear cells: neutrophils, eosonophils and basophils. Progenitor cell is pluripotent and can differentiate into different types of cells. B/t cells a part of the adaptive immunity see antigen and start producing antibodys. T cells need to be presented with an antigen to start immune response. Cd8+ = apoptosis going to kill if it doesn"t have the right amount of mhc complex.
