Document Summary

Describe the composition of blood (plasma and formed elements) Describe the structure and function of rbcs; structure and properties of hemoglobin. Only fluid tissue in body (both cellular and liquid components) Ph 7. 35-7. 45, 38 c, 5-6l in males, 4-5l in females, 8% of body mass, red, metallic taste. Distribution (oxygen, nutrients, metabolic wastes , hormones) Regulation (maintains appropriate body temp, normal ph adequate fluid volume) Protection (prevents blood loss, prevents infections- antibodies, wbcs) Biconcave disks huge surface area compared to volume to transport gasses. Contain spectrin gives them their flexibility and allow them to change shape. Filled with hemoglobin (protein in gas transport) Hemoglobin is enclosed as to not damage any tissues or kidneys. Hb composed of globin 2 alpha & 2 beta chains each bound to heme group. Heme group bears an atom of iron which can bind to 1 o2 molecule molecue can carry 4 o2 molecules. Deoxyhemoglobin= hb after o2 diffuses into tissues.
