Document Summary

In a blood cell, 55% is plasma in a medium for transporting materials in the blood and 45% is formed elements that consist of the red blood cells, white blood cells and platelets. White blood cells defend body against diseases during infection, the number of wbc increases dramatically. Platelets are cell fragments essential in blood clotting. Continuous production and movement of cells into blood. Stem cells are undifferent cells in the red bone marrow that give rise to all the formed elements: erythroblast, myeloblast, monoblast, lymphoblast and megakaryoblast. Mature formed elements are specialized for specific functions. White blood cells (leukocytes) granulocytes, agranulocytes lymphocyte: b-cells, t-cells, nk-cells and nkt-cells. White blood cells migrate into and out of peripheral tissues White blood cells exit a capillary by squeezing between the cells of the vessel walls and migrate into tissues red blood cells and platelets do not migrate into tissue they stay in capillary.

Without enough red blood cells, you can't bring oxygen to thetissues in your body.
