2. Renal Function and Dialysis Metabolism of protein in your diet produces urea as a byproduct. The rate of urea production (r_u) depends on how much protein you eat and how big you are (measured by your body fluid volume, V). A realistic urea production rate for an average person (\/=40 L) is about r_u= 15 mg/min. Urea produced in the liver is rapidly distributed throughout the body's fluid volume V; the average urea concentration in the body's fluids is...

Question 1 (1 point) All of the following statements about bicarbonate ions are true EXCEPT: bicarbonate ions are excreted in the urine in proportion to hydrogen ion excretion. the kidneys are capable of synthesizing new bicarbonate ions. O the kidneys can reabsorb bicarbonate ions. O bicarbonate ions act in a chemical buffer system as a weak base. there is many more bicarbonate ions than carbonic acid molecules in the carbonic acid-bicarbonate buffer system. Question 2 (1 point) Which of these...

24. In mammals, urine formation occurs in a pair of kidneys. Each human kidney contains about a million tubelike- blood-filtering units called nephrons. Urine compositions and volume depend on three processes: filtration, reabsorption, and secretion. Which of the following does not match the process named? a. filtration: blood enters Bowman's capsule of glomerulus b. reabsorption: water and solutes selectively return to blood capillaries c. secretion: excess ions and some other substances move from blood capillaries into the nephrons d. all...
