Document Summary
As mammals evolved they lost their nucleus (with this it enables rbcs to create (cid:373)o(cid:396)e he(cid:373)oglo(cid:271)i(cid:374), (cid:449)hi(cid:272)h i(cid:374)(cid:272)(cid:396)eases Erythrocytes/ rbcs are about 1/3 hemoglobin (heme= iron containing portion, hemoglobin= protein portion) Oxyhemoglobin= found in arteries in body (systemic circular system); is bright red. Deoxyhemoglobi(cid:374) blood e(cid:374)te(cid:396)i(cid:374)g the s(cid:455)ste(cid:373)i(cid:272) (cid:448)ei(cid:374)s is low i(cid:374) o(cid:454)(cid:455)ge(cid:374); is darker red (but not blue) Rbc will increase in number if you reach higher altitudes. Leukocytes/ wbcs (leuko= white): primary function is to defend the body. There are 5 categories of leukocytes (come from the same stem cell; once produced can have one or more nuclei that are strangely shaped; unlike rbc they can reproduce) Wbc capable of amoeboid movement and are able to squeeze into and out of capillaries (fig. More red than white blood cells (ranges from 5000- 10 000 cells/ mm3) Count lower than 5000 or more than 10 000 can mean have disease/ condition.
