Document Summary
Intro to blood & central nervous system (cns: composition of blood & functions, whole blood. Organic nutrients - glucose, amino acids (aa), lactic acid (la), Blood serum = plasma without brinogen (inactive form of brin) Erythrocytes (rbcs) - mainly for gas transport, a-nucleate cells, hematocrit. = % of rbcs in wb (usually 38-43%) Leucocytes (wbcs) - for immunity, 5 categories. Thrombocytes (platelet) - for blood clotting (coagulation), hemostasis. Functions of blood: controls acidity/alkalinity of blood with protein buffers and bicarbonates, immunological - ability to coagulate on cue to close wounds ( brinogen > brin) Takes place in the proximal epiphysis of long bones. Hemocytoblast - erythropoietin stimulates myeloid stem cells to give rise to proerythroblasts, which give rise to normoblasts/orthochromatic erythroblasts (nbs) which the nucleus is removed from, which gives rise to reticulocytes (look like rbcs) which give rise to rbcs.
