Document Summary
Formed element: a cell, cell remnant, or cell fragment. Erythrocyte: type of formed element, red blood cell, carry respiratory gases, 45% of our total blood volume. Leukocyte: type of formed element, white blood cell, primarily fight infection, 5 types, displays positive chemotaxis. Platelet: type of formed element, broken off piece of red blood cell, has granules containing clotting chemicals. Plasma: liquid portion of our blood, 55% of our blood volume, many proteins. Gamma globulins (antibodies: also has wastes, nutrients, electrolytes, some respiratory gases. Hematocrit: device used to determine blood composition, see separation of plasma and cells. Hemoglobin: heme pigment bound to globin protein, this complex gives blood its red color and can carry up to 4 oxygen. Iron at its core which binds up to 4 oxygen at once. Composed of 4 polypeptide chains (2 alpha and 2 beta: 250 million per red blood cell. Oxyhemoglobin/deoxyhemoglobin graph: s shape tells us:
