Document Summary
Physl 212 - lecture #19 - blood cells of the body. However : erythryopoietin (epo) occurs = rbc = oxygen in tissues. Rbc count = thickness of blood = viscosity of blood = flow of blood = speed = oxygen carried. Conditions that changes blood flow (that is, decrease it) causes conditions that favours blood clots. Basically not enough oxygen getting to the tissues. Oxygen-carrying capacity of blood due to rbcs and/or hemglobin in the. Production of rbcs in bone marrow. Hemolytic anemias: destruction of rbcs in body. Hemorrhagic anemias: loss of rbcs from body [loss of blood] Epo, which may lead to chronic kidney disease. Aplastic anemia: damage to bone marrow hemolytic amnesias. Abnormal rbcs shape, immune reactions or physical damage to rbcs = Round rbcs cannot squeeze through small spaces. Hemorrhagic anemias, from acute or chronic reasons (menstruation, bleeding ulcers) Ulcer: small amounts of blood loss over a long period of time.
