Document Summary
Chapter 1 homeostasis: the foundation of physiology. Physiology is the study of body functions. Mechanistic approach: explanation of body functions in terms of mechanisms of action: that is the. How of events that occur in the body. Plasma mem control movement of materials into and out of the cell. Basic cell function (read slides for basic functions) Gland cells: secrete digestive enzymes that help break food. Kidney cells: eliminates unwanted substances in the urine. Muscle cells: helps in muscle contraction. Electrolyte is a medical/scientific term for salts, specifically ions. Your kidneys work to keep the electrolyte concentrations in your blood constant despite changes in your body. For example, when you exercise heavily, you lose electrolytes in your sweat, particularly sodium and potassium. These electrolytes must be replaced to keep the electrolyte concentrations of your body fluids constant. So, many sports drinks have sodium chloride or potassium chloride added to them.
