Document Summary
Maintains normal volume and composition of body fluid compartments. Helps maintain blood pressure, hemoglobin levels and calcium levels through hormone secretion. Filters a large volume of plasma water and solutes (at the glomerulus) Filtered fluid enters tubules which add or remove water and solutes to form the final urine, which is excreted. Secretes hormones in response to changes in blood pressure, hemoglobin and calcium. Know the body fluid compartments and what determines their volume and composition. Understand the factors which regulate glomerular filtration. Understand how tubules regulate the excretion of sodium, potassium, water and hydrogen ion. Understand the physiology of renin/angiotensin, erythropoietin and vitamin d. Case of the day: the seizing marathoner. A 45 year old women runs her first marathon after 6 months of training.
