Question
Chapter 33, Problem 2PIT
Summary Introduction
To add:
The terms glomerulus, proximal convoluted tubule, nephron loop, and distal convoluted tubule to the concept map.
Concept introduction:
The urinary system is responsible for removal of harmful substances from the body by the process of excretion. The process results in formation of urine, which is formed in the nephrons of the kidneys.

- 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.arrow_forwardMatch each .structure with a function. _____ ureter a. start of nephron _____ Bowmans capsule b. delivers urine to body surface _____ urethra c. carries urine from kidney to bladder _____ collecting tubules d. secretes ADH _____ glomerulus e. target to aldosterone _____ pituitary gland f. cluster of leaky capillariesarrow_forwardWhich of the following correctly describes a part of kidney function? a. Collecting ducts dilute urine because they are permeable tosalt but not water. b. In the ascending loop of Henle, Na1 and Cl2 move into thetubules because the osmolarity of the filtrate is increased. c. The descending loop of Henle receives filtrate from theascending loop. d. The distal convoluted tubule pumps water into the tubule byactive transport. e. The renal pelvis receives urine from the collecting ducts andcarries it to the ureters.arrow_forward
- 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.arrow_forwardWhich 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) podocytesarrow_forwardThe primary structure found within the medulla is the ________. loop of Henle minor calyces portal system ureterarrow_forward

Cortexarrow_forwardAs the text noted, two-thirds of the water and solutes that the body reclaims by reabsorption in nephrons occurs in the proximal tubule. Proximal tubule cells have large numbers of mitochondria and demand a great deal of oxygen. Explain why.arrow_forward15. Use the diagram to answer the following questions. Some labels from the diagram may be used once, more than once or not at all.Label "10" corresponds to ureter urethra Cowper's gland epididymisarrow_forward
