- Red blood count (RBC)
- Extrinsic pathway
- a number of red blood cells per microliter of blood
- b Transport of gases by hemoglobin bound to carbon monoxide. At the same time hemoglobin binds to oxygen, (one O2 per heme group), nitric oxide produced by endothelial cells lining the blood vessels is also bound to the amino acid cysteine contained within the beta globin. When hemoglobin releases oxygen to the tissues nitric oxide is released as well which causes the relaxation of smooth muscle in the walls of blood vessels thus decreasing blood pressure.
- c transfer of blood or blood components from one individual to another
- d Immunity, increase due to viral infection, smallest, stimulate production of antibodies
- e begins with chemicals outside of the blood. Thromboplastin, or tissue factor (TF), is released activating factor X and beginning a common pathway.
5 Multiple choice questions
- White blood cells. Protect body against microorganisms and remove dead cells and debris. Movements- Ameboid, Diapedesis, Chemotaxis. Types- neutrophils, eosinophiles, basophils, lymphocytes, monocytes.
- All formed elements derived from a single population in the red marrow. Proerythroblasts, meyloblasts, lymphoblasts, monoblasts, megakaryoblasts.
- Cell fragments pinched off from megakaryocytes in red bone marrow. Important in preventing blood loss by platelet plugs and promoting formation and contraction of clots
- Develop into lymphocytes
- stoppage of bleeding caused by coagulation of blood, platelet plug formation, and vascular spasm
5 True/False questions
Erythrocytes → Red Blood Cells. Biconcave, anucleate. Made up of Hemoglobin, lipids, ATP, and carbonic anhydrase. Transport oxygen from lungs to tissues and carbon dioxide from tissues to lungs
ABO blood group → rhesus monkeys first studied, people are positive with the Rh antigen, negative without it. People that are positive have D antigens on their red blood cells. Antibodies against the Rh-antigen do not develop unless Rh-negative person is exposed to Rh-positive blood.
Fibrinogen → 4% Responsible for formation of blood clots. (also platelets)
Erythrocytosis → overabundance of RBC increased blood viscosity, reduced flow rates, and plugging of capillaries
Colloid → Liquid containing suspended substances that don't settle out. 58% Albumin, 38% Globulins, 4% Fibrinogen, and other solutes such as nutrients, waste products, gases, regulatory substances, and ions.
