Drugs that increase urine volume are called diuretics. Some diureticsinhibit the active transport of Na+ in the renal tubule. Explain how thesediuretic drugs cause increased urine volume.

Which of these is least likely to promote renin secretion by the juxtaglomerular cells? Group of answer choices Decreased renal perfusion Sympathetic stimulation Increased renal Na+ reabsorption β 1 agonists

An increase in the permeability of the cells of the collecting tubule to water could result from all of the following except: an increase in the production of aldosterone. an increase in the release of ANG II. an increase in the osmolarity of the blood. a decrease in blood volume. a decrease in the osmolarity of the filtrate.

These vessels marked by the white arrow 1.  are classified as 'cap bed 1' vessels in the renal portal system 2.  function to secrete glucose molecules across the wall of the proximal convoluted tubule 3.  move hydrogen ions across their endothelial cells into the lining cells of the proximal convoluted tubule for pH regulation (if the blood is in acidosis) 4.  secrete the products of drugs metabolism into the filtrate of the proximal convoluted tubules Choose from the following: (A) 1 and 2 (B) 2 and 3 (C) 1 and 3 (D) 1, 2, and 3 (E) 3 only (F) 4 only (G) 1, 2, 3, and 4
