Q9 **Question:** Podocytes are characteristic of filtration sites of metanephridia.- ○ True- ○ False**Explanation:** This question pertains to the biological structure and function of podocytes and metanephridia. Podocytes are specialized cells typically found in the kidneys of vertebrates, playing a key role in the filtration process of the nephron, not in metanephridia. Metanephridia, on the other hand, are excretory systems found in some invertebrates, such as annelids. Understanding the correct associations is crucial for learning about different excretory systems across species.

Figure 41.6 Which of the following statements about the nephron is false? The collecting duct empties into the distal convoluted tubule. The Bowman’s capsule surrounds the glomerulus. The loop of Henle is between the proximal and distal convoluted tubules. The loop of Henle empties into the distal convoluted tubule.
Which of the following does not contribute to the process of filtration? (a) active transport by epithelial cells lining renal tubules (b) large surface area for filtration (c) low permeability of glomerular capillaries (d) high hydrostatic blood pressure in glomerular capillaries (e) podocytes
Which of the following does not contribute to the high salt concentration in the interstitial fluid of the kidney medulla? (a) active transport of sodium from the upper part of the ascending limb (b) diffusion of salt from the ascending limb of the loop of Henle (c) reabsorption of salt from various regions of Bowmans capsule (d) counterflow of fluid through the two limbs of the loop of Henle (e) diffusion of urea out of the collecting duct
Fatty tissue holds the kidneys in place. Extremely rapid weight loss may cause this tissue to shrink so that the kidneys slip from their normal position. On rare occasions, the slippage can put a kink in one or both ureters and block urine flow. Suggest what might then happen to the kidneys.
Which of the following is an example of autoregulation of kidney function? a. The RAAS regulates Na1 by secreting renin when blood pressure or blood volume decreases. b. The ADH system regulates water balance by decreasing water reabsorption and increasing excretion of salt. c. Receptors in the juxtaglomerular apparatus detect a higher salt concentration in the distal convoluted tubule and trigger constriction of the afferent arteriole to reduce glomerular filtration rate. d. ANF is released by the kidney to increase renin release. e. Angiotensin II lowers blood pressure by constricting arterioles.
Figure 41.5 Which of the following statements about the kidney is false? The renal pelvis drains into the ureter. The renal pyramids are in the medulla. The cortex covers the capsule. Nephrons are in the renal cortex.
