Chapter 15, Problem 1AWK
Summary Introduction
To review:
The workload on the kidneys after a person consumes a salty snack and a beverage.
Introduction:
The excess amount of salt and water are readily excreted through the kidneys. Unlike normal conditions with a normal salt and water intake, here the kidneys have to work harder to get rid of the extra ions. This is essential for the maintenance of the ionic balance in the blood, which in turn, maintains homeostasis.

- Drinking too much water can be a bad thing. If someone sweats heavily and drinks lots of water, their sodium levels drop. The resulting water intoxication can be fatal. Why is the sodium balance so important?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_forwardYour feedback loop descriptions should include the following terms: thirst, ADH, hypothalamus, neuron, pituitary gland, nephron, kidney, urine, reabsorption, osmoreceptors. I have to Idea how to make a feed back loop about thisarrow_forward
- On a particularly busy day, a student taking Anatomy and Physiology does not have anything to drink from 9:30 am until 6:30 pm. Osmoreceptors in the brain detect the decreased level of water in the blood. These receptors send a signal to the hypothalamus/posterior pituitary, which stimulates the release of antidiuretic hormone (ADH). This hormone acts on the nephron tubules and collecting ducts in the kidney to increase reabsorption of water, which returns that water to the blood. This retention of water has the additional effect of decreasing urinary output. As the fluid levels in the blood stabilize, the release of ADH ends.1. Whatisthevariablemonitoredbythisloop?2.

O True O Falsearrow_forwardSome people advocate drinking one’s own urine, claiming significant health benefits. What problems do you see with this “alternative therapy”? Are there conditions under which this might be advisable?arrow_forward
- When blood plasma pH gets too low kidneys can produce more HCO3- because: Multiple Choice more HCO3- can be filtered by the glomerulus less HCO3- is being reabsorbed in the proximal convoluted tubule less HCO3- can be filtered by the glomerulus renal tubule cells can make more HCO3- from certain substratesarrow_forwardThe nephridia of an earthworm excretes urea because: O a. Worms cannot produce the enzymes needed to produce uric acid. O b. The urea is used to alter the osmotic pressure of the earthworm. O. Ammonium cannot diffuse out through the skin. O d. Urea is completely non-toxic. Oe. Urea does not result in any water loss.arrow_forwardWhich 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_forward
- What is glucose important for your body? Why is glucose especially important for the brain? Should glucose be in the blood of a healthy individual? Is it small? Does it get filtered through the filtration membrane at the glomerulus? Do you want to let glucose out in your urine? If glucose if filtered, but you want to keep it, what process does the nephron do to keep it? Should you have glucose in your urine if you are a normal healthy individual? What is a transport maximum? It means that we have so much glucose in the blood and in the filtrate that we cannot: _______________ it all. What hormone allows glucose to move from your blood INTO your cells? This hormone is the “key” that opens the “locked door” into your cells. What happens if you have diabetes mellitus and cannot produce (or produce enough) insulin? What symptoms does someone with diabetes mellitus (type I or type II)? Specifically:arrow_forwardThe role of the liver in excretion is the production of urea from:A ammoniaB uric acidC fatty acidsarrow_forwardDrinking 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_forward
