BIOL-2230 Lecture Notes - Lecture 6: Protein Subunit, Globin, Red Blood Cell
Document Summary
Formed elements (living parts: erythrocytes or red blood cells. Make up 45% of total blood volume: the amount in your blood is your hematocrit levels, men have slightly more than females do. They have no nuclei or organelles: leukocytes or white blood cells. White blood cells and platelets make up less than 1% of blood volume: platelets. Plamsa: liquid, sticky portion of blood. Straw-colored: caries a lot of proteins and other nutrients, 55% of total blood composition. Water: 90% of plasma: helps with dissolving and absorbing heat. Albumin: a protein that acts as a carrier (60% of carrying: helps with blood pressure, made by liver. Globulins- make up 36% of proteins: alpha and beta act as carriers, gamma-contribute to the immune response. Small, biconcave discs (flat with dips in center) Has hemoglobin attached and functions to transport gasses: specifically oxygen and carbon dioxide. The antioxidant enzymes allow free radicals to be disposed of.
