The amount of fluid retained in the body is regulated by both a)aldosterone and insulin. b) erythropoietin and secretin. c) aldosterone and antidiuretic hormone. d) antidiuretic hormone andd gastrin. It was observed that an experimental subject consistently passed a larger volume of urine after consuming three cups of black unsweetened tea containing caffeine than after consuming an equal volume of sweetened lemonade. Assume all other variables were carefully controlled. Which hypothesis is based on an appropriate body response to the active ingredient identified in the beverage ? a) The caffeine in the tea caused a reduction in the secretion of ADH by the pituitary gland. b) The sugar in the lemonade provided additional energy for the active transport of water out of the nephrons. c) The caffeine in the tea caused the liver to produce more urea. d) The sugar in the lemonade blocked the reabsorption of water by the distal tubules of the kidney. After an individual drinks large quantities of water, the blood becomes slightly diluted. The body immediately reacts by a) increasing the secretion of ADH. b) reabsorbing more sodium ions from the filtrate of the nephron into the blood. c) increasing the secretion of aldosterone from the adrenal glands. d) decreasing the secretion of ADH. In an artificial kidney, blood is pumped through dialysis tubing (semipermeable tubing) which is immersed in a tank of washing or dialyzing solution. The blood is cleansed because a) urea and other impurities diffuse into the wash solution. b) chemical cleansers diffuse into the blood from the wash solution. c) water from the wash solution enters the blood by osmosis. d) poisons from the blood are actively transported out of the tubing. Dialysis machines purify blood by passing it through semi-permeable cellophane tubing immersed in a tank of dialysing fluid. Wastes are transferred through the tubing into the fluid. A system of this type can perform all the functions of a normal kidney except the a) diffusion of salts into the blood. b) active transport of substances out of the blood. c) filtration of smaller particles into the nephron. d) osmosis of water into the collecting duct. An activity that increases as a result of untreated diabetes mellitus is a)storage of energy for tissue activities. b) use of sugar by tissue cells. c) release of insulin from the pancreas. d) excretion of glucose by the kidneys. Arteriolar dilation throughout the body would cause urine production to decrease because the a)osmotic pressure of the blood plasma would decrease. b) osmotic pressure of the blood plasma would increase. c) blood pressure in the glomerular capillaries would increase. d) blood pressure in the glomerular capillaries would decrease please help i dont understand
