HSC 215 Lecture Notes - Lecture 11: Bone Marrow, Myeloid Tissue, List Of Foundation Universe Planets
Document Summary
Function: transportation, regulation, protection ph: 7. 35-7. 45 (if it gets to 7. 6you could be dead) Consists of three types of specialized cellular elements suspended in plasma (liquid portion of blood: formed elements= cells in blood, erythrocytes erythro= red cyte= cell. Occurs in red bone marrow/ myeloid tissue: immunoglobullins- antibodies, fibrinogen and prothrombin- blood clotting, albumins. Differentiates according to chemicals communicating body needs. Details of formed elements: red blood cells (rbcs) Biconcave disc; thin, flexible and large surface area. Protein composed of four highly folded polypeptide chains. Affinity for carbon dioxide: to form Five different types of circulating leukocytes: neutrophils, eosinophils, basophils, monocytes, lymphocytes. Emts of white blood cells: eosinophils: parasitic worms and allergies, basophils: mast cells contain histamine. Fight against allergies: agranulocytes, monocytes: phagocytes/ macrophages. 2nd to the scene of an injury. 3: lymphocytes: immunity ( attack viruses and bacteria, also store that information to build immune system up )
