BMS 300-Exam 4 (Passed!)

The three functions of the renal system are: correct answers Remove nitrogenous waste, regulate salt and water balance, regulate blood pH T/F: The glomerulus is a tuft of capillaries in the renal compartment and Bowman's capsule is part of the blood vascular compartment correct answers False T/F: Arterial blood from the renal artery goes to the capillaries in the renal cortex. correct answers True Water moves from Bowman's capsule into the glomerular capillaries because the: correct answers osmotic pressure generated by plasma proteins is higher in the capillaries than in Bowman's capsule Which of the following are part of the nephron? correct answers -Bowman's capsule -proximal convoluted tubule -descending limb of the loop of the nephron -ascending limb of the loop of the nephron -distal convoluted tubule In the proximal convoluted tubule water and most ions follow a ___ route, meaning they leave the lumen by passing between the tight junctions of the epithelial cells. correct answers Paracellular When Na+, glucose and amino acids move in across the epithelial cells of the proximal convoluted tubule, they are reabsorbed by the ________________. correct answers Peritubular capillary The peritubular capillary is an extension of the efferent arteriole which wraps around the ___. correct answers Proximal convoluted tubule GLUT 2 is a glucose transporter that permits glucose transport by facilitated diffusion. You would expect to find this protein in: correct answers Basilar membranes of epithelial cells in the proximal convoluted tubule T/F: The concentration increases as the filtrate moves from the cortex to the medulla. correct answers True T/F: The thick segment of the ascending limb contains passive ion channels and the thin ascending limb contains ion channels requiring ATP. correct answers False The descending limb only contains ___ and lacks ___. correct answers Aquaporins, ion channels The Na+ driven co-transporters for glucose and amino acids are located on what side of the membrane? correct answers Apical
