1. The first portion of the loop of Henle dips into the medulla where it is called the ascending limb of the loop of Henle. True or False. 2. A juxtamedullary nephron usually has its glomerulus deep in the cortex close to the medulla, and its long loop of Henle stretches through the medulla. True or False. 3. Each renal corpuscle receives one efferent arteriole, which divides into the tangled capillary network called the glomerulus. True or False. 4. Each efferent arteriole of a cortical nephron divides to form a network of capillaries called the peritubular capillaries. True or False. 5. The first step in the production of urine is called tubular reabsorption. True or False. 6. When blood flows into the glomerular capillaries more rapidly, glomerular filtration rate decreases. True or False.

Step 1
" This statement is false because the first portion of the loop of Henle that dips into the medulla is the descending limb, not the ascending limb. The loop of Henle has two limbs: the descending limb goes down into the medulla, and the ascending limb comes back up Show more…

Select true or false for each of the following options regarding the descending limb of the loop of Henle. A) Utilizes both facilitated diffusion and active transport to remove solutes from filtrate. B) NaCl pumps allow filtrate to be 300 mOsm less than surrounding interstitial fluid. C) Includes aquaporins that allow water to leave and concentrate filtrate. D) Allows diffusion of urea that contributes to the osmotic concentration gradient of interstitial fluid. 2. TRUE or FALSE: The distal tubule is where the maximal osmolarity of the filtrate within the collecting duct of the nephron is set.

I. TRUE FALSE 1. The intercalated cells of the proximal convoluted tubules have receptors for aldosterone and ADH. 2. The ascending loop of Henle is impermeable to water and the descending loop is permeable. 3. COPD includes emphysema and chronic bronchitis. 4. Microvilli are present in the small intestine. 5. Villi are only present in the small intestine and contain branches of mesenteric veins and arteries for absorption of nutrients. 6. Haustra, goblet cells, epiploic appendages, microvilli, and taenia coli occur in the colon. 7. Some vitamins, like vitamin C, are produced in the large intestine by normal microbiota. 8. Almost all of the absorbed glucose, amino acids, and fats are sent to the liver in the hepatic vein. 9. Constriction of mesangial cells and the afferent arteriole will decrease GFR (glomerular filtration rate). 10. If A is dominant over a, then Aa would have the same phenotype as AA. 11. Podocytes are found in the inner layer of Bowman's capsule and form part of the filtration membrane. 12. Lupus, Graves disease, osteoarthritis, myasthenia gravis, Hashimoto's thyroiditis, and type II diabetes are autoimmune diseases. 13. The plasma membrane of the oocyte contains some of the sperm receptors, and the zona pellucida contains the other (specifically zp3).
