) The tubuloglomerular feedback mechanism responds to an increase in a.) A) urine production by signaling for a decrease in urine production through the hormone ADH. b.) glomerular capillary hydrostatic pressure by signaling for afferent arterioles to constrict and increase filtration rate. c.) Nacl concentration in tubular fluid by signaling for afferent arteriole constriction with local chemical messengers. d.) systemic blood pressure by signaling for a decrease in heart rate through blood-borne hormones.

This diagram illustrates which of the following Choose from the following: (A) secretion of hydrogen via Na+/H+ exchange ions by the proximal convoluted tubule   (B) reabsorption of bicarbonate ions by intercalated cells (A) in the collecting duct   (C) secretion of H+ by H+K+/ATPase pumps in the intercalated cells (A) in the collecting duct   (D) A and B   (E) all of the above

Pressure in the renal artery is 100 mm Hg and the pressure in the renal vein is 50 mm Hg. The resistance of the afferent arteriole equals 0.5 mm Hg•min/L and the resistance of the efferent arteriole equals 0.5 mm Hg•min/L. What is the pressure in the glomerulus?
