Chapter 37, Problem 6TY
Summary Introduction
Introduction:
The antidiuretic hormone is involved in the amount of water management inside the body. This hormone is secreted by the hypothalamus and pituitary gland found above the kidneys. The epithelial cell of the collecting duct is very permeable which helps in the retaining of water and is regulated by ADH. The presence If ADH inside the blood increases the number of water channels termed as aquaporins.

Which of the following is an accurate statement about vasopressin?
Multiple Choice
It is the endogenic form of ADH.
It contains ADH and oxytocin in a ratio of 10:1.
It is metabolized and excreted by the liver and kidneys.
It is administered intranasally to stabilize patients' fluid balance.
When antidiuretic hormone (ADH) levels are low this causes ________.
less of the water reaching the collecting ducts to be reabsorbed
more aquaporins to be activated to increase the reabsorption of water
vasodilation of the efferent arteriole to increase the glomerular filtration rate
the urine to have a very high concentration of ions and nitrogenous wastes
Which of the following are an effect of angiotensin II production?
Select all that apply.
Group of answer choices
ADH release
Rise in blood pressure
Aldosterone release
Vasodilation

- As 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_forwardFatty 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.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_forward
- 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_forwardFigure 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.arrow_forwardWater and small solutes enter nephrons during ________. a. filtration b. reabsorption c. secretion d. both a and barrow_forward
- Which of the following is incorrectly matched? PCT - facilitated diffusion of glucosedescending loop of Henle - sodium reabsorptioncollecting duct - water reabsorptionDCT - reabsorption of bicarbonate ionsglomerulus - high pressure filtrationarrow_forwardA 65-year-old male patient is prescribed an ACE ( Angiotensin-converting enzyme) inhibitor (Benazepril ) for the treatment of hypertension. Which statement below is incorrect? Angiotensin II causes constriction of the vessels and triggers the release of aldosterone. ACE Inhibitors prevent Angiotensinogen I from converting to Angiotensin II. Kidneys will excrete water and potassium. This medication will lower SVR (systemic vascular resistance) and blood pressure.arrow_forwardFiltration of substances out of the glomerulus occurs because: Charged molecules cannot cross as easily as uncharged, nonpolar molecules.Wastes cross into the filtrate and nutrients remain in the blood.The difference in size between the afferent and efferent arterioles creates high pressure.There are only channels for certain types of molecules in the glomerular wall.Active transport helps needed nutrients crossarrow_forward
- Which of the following is NOT a function of the excretory system? * Filtration of wastes from the blood. Secretion of ADH from the collecting duct. Maintaining pH balance by secretion of H+ ions. Osmoregulation via sweating. Releasing carbon dioxide waste from the lungs.arrow_forwardIs this following statement correct? In the kidney, vasoconstriction of the afferent arteriole increases glomerular filtration rate, because hydrostatic pressure in the glomerular capillaries increases (much like putting your thumb over the end of a garden hose increases the pressure and causes the water to exit the hose with greater velocity and travel a greater distance).arrow_forwardTrue or false?glomerular capillaries are more porous than other capillaries True or false? increased ph of cerebrospinal fluid triggers an increase in tidal volume and respiratory rate to compensate True or false? water movement in and out cells is due mainly to fluctuation of the na+ and k+ ion concentrationsarrow_forward
