Erythrocytes Survive 120 Days Hemoglobin * Globin: 4 folded polypeptide chains * Heme: Iron group in each polypeptide that binds 02 Enzymes: * Glycolytic: generate energy through glycolysis due to lack of mitochondria * Carbonic anhydrase: for transport of CO2 into HCO3 Erythropoiesis: * regeneration of new cells in the bone marrow Erythropoietin (hormone): * when kidneys detect not enough 02 they secrete this hormone which stimulates erythropoiesis‚ increasing 02 capacity

INTRODUCTION TO PHYSIOLOGY AND HOMEOSTATIS PHYSIOLOGY 1.1 Intro to Physiology Physiology: the study of the functions of living things‚ how the human body works Two approaches explain the events that occur in body -purpose of the body process - mechanism in which the process occurs Physiologists view the body as a machine whose mechanisms of action can explained in terms of cause and effect sequences of physical and chemical processes. Physiology is closely related to anatomy: the study
