Which of these is not a function of the kidneys?
A) The kidneys regulate the plasma volume
B) The kidneys help to regulate blood pressure
C) The kidneys help control the rate of red blood cell production
D) The kidneys deactivate vitamin D and stimulate the activity of osteoclasts
Why are humans not able to meet their water requirements by drinking seawater? Assume seawater has a concentration of 1400 mOsM. In your explanation, consider both the renal system and the digestive system. Additionally, describe the physiology of two symptoms of excessive seawater consumption that occur prior to death.
How do diuretics work to reduce excess fluid in the body? Describe the mechanisms of action for three types of diuretics.

- 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_forwardWhy is excretion important in order to achieve osmotic balance?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
- Explain how the heart, kidneys, and several glands all work together to cause the excretion of more sodium ions in the urine when a person has eaten salty food?arrow_forwardCompare urinalysis data from a person with diabetes to data from a person without diabetes.arrow_forwardPart 1 Marina is taking a drug that is metabolized into pharmacologically inert, water-soluble by-products before being excreted. What will be the effect of this process?  A. Marina's body will be less able to reabsorb the substance before it is excreted. B, Marina's body will be more likely to reabsorb the substance before it is excreted. C.The substance will be inactivated before it is excreted. D. The substance will have its strongest effect just before it is excreted.  Part 1a A drug administered via inhalation is absorbed through the nasal membranes and sinuses.  True Falsearrow_forward
- A report was received from an hospital that approximately 50% of patients with kidney problems were employee of a coffee industry. One of the main effects it has on their body is the increase in urine output over a 24 hour period. Use the scientific process to find the effect of coffee on the kidney and urine output.arrow_forwardHow would damage to the renal capillaries resulting in an increase in protein filtration and urinary excretion affect net filtration pressure in the systemic circulation? a. Increase capillary reabsorption due to an increase in interstitial colloid osmotic pressure b. Increase capillary filtration due to an increase in interstitial hydrostatic pressure c. Increase capillary filtration due to a decrease in blood colloid osmotic pressure d. Increase capillary reabsorption due to increased blood hydrostatic pressurearrow_forwardVarious drugs used to treat hypertension act through the kidney and urine filtration system. A common drug to treat hypertension is thiazide, which acts directly on the cells of the distal convoluted tubule. Hypothesize about why thiazide lowers blood pressure, based on the anatomical feature of the kidney it targets.arrow_forward
- Drinking seawater cannot prevent death by dehydration. What would result if humans attempted to alleviate their dehydration by drinking seawater? justify your answer by describing kidney physiology. why wouldn't reflexes, in response to dehydration, fully compensate and what does this illustrate about the force allowing kidneys to retain water under nromal conditions?arrow_forwardAngiotensin is a hormone that stimulates vasoconstriction and increases blood pressure. Which effect would also be expected from angiotensin function?  A. increased secretion of sodium in the kidney  B. decreased secretion of sodium in the kidneys  C. increased reabsorption of sodium in the kidneys  D. decreased reabsorption of sodium in the kidneysarrow_forwarddrugs known as potassium-sparing diuretics work by blocking the effects of aldosterone on the kidney. what effect would these drugs have on the amount of urine produced, on the blood pressure, and on potassium ion concentration in the blood? could these drugs have a negative impact on the acid-base balance of the body? explain.arrow_forward
