Question
Oxygen and carbon dioxide are transported across membranes to and from cells by a. Bulk transport b. Diffusion c. Vescicular transport d. Endocytosis e. Exocytosis 6. Peripheral tissue edema would result from a. b. c. d. Low blood albumin levels Congestive heart failure of the pulmonary circuit Blocked on inaccessible lymphatic vessels Any of the above 17. If congestive heart failure has progressed to the point of venous congestion in the systemic circuit kidneys will receive less blood flow; this would result in a. Increased aldosterone secretion b. Increased EPO secretion c. Decreased urine formation d. All of the above 18. How does blood pressure aid in the formation of urine? It regulates reabsorption of potassium It inhibits secretion of nitrogenous wastes The hydrostatic pressure in afferent capillaries favors the formation of glomerular filtrate The pressure of the blood favors reabsorption by contributing to osmotic pressure a. b. c· d. 19. The primary site of reabsorption of solutes within the nephron of the kidney is the a. Glomerulus b. Proximal convoluted tubule c. Collecting ducts d. Any of the above 20. Which of the following is NOT a homeostatic function of the kidney a. Regulation of blood volume b. Regulation of sodium and potassium in the blood c. Regulation of cardiac output d. Regulation of blood pHExplanation / Answer
15.B. Oxygen and carbon dioxide are transported across membranes to and from cells by diffusion as oxygen and carbon dioxide are the molecules which can move across the cell membranes through a simple diffusion.
16. B. Peripheral tissue edema would result from congestive heart failure of the pulmonary circuit.
