Question
Chapter 27, Problem 1DCR
Summary Introduction
To determine:
The reason behind Jason’s dehydration along with the process leading to dehydration.
Introduction:
To keep the body in a stable condition (homeostasis), it is important to maintain proper fluid content in the body. Amount of fluid being retained in the body is affected by different hormones.
Summary Introduction
To determine:
The hormone that regulates the amount of water in the urine and the effect of alcohol on the activity of this hormone.
Introduction:
Hormones are important for the survival and healthy functioning of the body. Different types of hormones also control different activities of the excretory system. Change in the activity or concentration of these hormones alters the activity of the excretory system.

A young man is involved in a motorcycle accident that fractures his sphenoid bone. Shortly thereafter, he begins to excrete enormous amounts of urine, up to 30 liters per day, and suffers intense thirst. His neurologist diagnoses the problem as diabetes insipidus. Explain how his head injury resulted in these effects on urinary function and thirst. Why would a sphenoid fracture be more likely than an occipital bone fracture to cause diabetes insipidus? What hormone imbalance resulted from this accident? Would you expect to find elevated glucose in the urine of this diabetic patient? Why or why not?
How does the secretion of ADH affect urine volume and urine concentration?
What factors increase the release of ADH from the posterior pituitary gland?
How would you alter the secretion of aldosterone and ADH to reabsorb more sodium without reabsorbing large quantities of water from the filtrate?
Osmoregulation is a process that helps control the amount of water in
the blood stream. One of the main hormones involved in this is ADH,
which is released by the posterior pituitary gland
a) With reference to at least this hormone, explain the negative
feedback mechanism that occurs when the body is
dehydrated.
b) Following on from the above, explain what happens when
there is too much water in the blood stream. Again you should
refer to ADH as part of your answer.

- Vasopressin is a hormone that is mainly released when the body lacks water. The release of vasopressin causes the kidneys to conserve water by concentrating urine and decreasing urine output. However, vasopressin also has additional functions in other tissues such as the brain and blood vessels, which are not directly involved in urine production. How might vasopressin trigger different responses in different tissues?arrow_forward1.) Discuss how alcohol affects anti-diruetic hormones and how it results in dehydration. 2.) Why are lipid soluble drugs not excreted in the urine, what has to happen in order for them to be excreted?arrow_forwardEnzo, a 56-year-old man, woke up on a chilly morning with the feeling that he needed to urinate. As he was reluctant to get out of bed, Enzo distracted himself by reading online news stories on his iPad until the urge to urinate returned sometime later. When he went to the toilet to relieve himself, it took a while to empty his bladder due to the slow urine stream.Explain how Enzo was able to delay going to the toilet when he first felt the urge to urinate, and the process involved in eliminating urine from his body when the time was right.arrow_forward
- In patients with diabetes mellitus, not enough insulin is produced; as a consequence, blood glucose levels increase. If blood glucose levels rise high enough, the kidneys are unable to absorb the glucose from the glomerular filtrate, and glucose "spills over" into the urine. What effect does this glucose have on urine concentration and volume? How does the body adjust to the excess glucose in the urine?arrow_forwardThe major action of ADH in the kidneys is to:a. increase water absorption by the proximal convoluted tubule.b. increase glomerular filtration rate.c. increase water reabsorption by the collecting duct.d. increase potassium’s excretion.arrow_forwardHormones released by endocrine glands 1) ACTH 2) Cortisol 3) Thyroxine 4) Aldosterone 5) Epinephrine 6) ADH. Match the following to the number above a) ________: returns the sodium ion concentration in the blood back to normal after sweating. b) ________: Decreased secretion leads to an excessive amount of urine. c) _________: Stimulates the release of the hormone responsible for increases in blood sugar. d) ________: Excessive secretion leads to weight loss.arrow_forward
- You have read that aldosterone causes sodium ion retention from the kidneys. How would blocking aldosterone secretion decrease the amount of water retained from the fluid in the kidneys?arrow_forwardPart A Why is control over blood [Ca2+] and [Red Blood Cell] crucial? Choose one hormone involved in either of these homeostatic systems that regulate the concentration of these ions/cells and describe how it functions in homeostasis. Remember to include the name of the gland that secretes it. Part B Choose one molecule that is reabsorbed by the nephron and describe the process by which it is reabsorbed.arrow_forwardJames experienced unexplained weight loss, fatigue, and lowblood pressure. After running several tests, his physicianconcluded that James had Addison disease, which involvesdecreased aldosterone production by the adrenal gland. When aldosterone production falls too low, certain kidney cells are unable totransport Na+ back into the blood.Predict 51) How does Addison disease affect Na+levels in the urine?2) Would you expect James’s urine volume to be higher or lowerthan normal? Explain your answer.arrow_forward
- Antidiuretic hormone (ADH) is produced in the pituitary gland and regulates the body's fluid volume and osmolality by affecting the number of active aquaporins (water channels) in the proximal tubules and the collecting duct. But what is it, above all, that drives the filtrate out of the tubules? a) Osmotic pressure formed depending on the composition of the filtrate b) Osmotic gradient in the medullary (kidney marrow) c) Hydrostatic pressure from the filtrate in tubules d) Blood pressure in the capillaryarrow_forwardIf blood osmolarity increases, receptors in the_______ detect this and signal the gland to increase release of________ . This hormone acts on the walls of the_____ and the______, causing them to insert more water porescalled_______ into their membranes and, thus, cause the urine to become more______ .arrow_forwardThe voiding reflex allows the sensation of the urge to urinated but prevents uncontrol urination by A stimulating parasympathetic stimulation of the detrusor muscle B inhibiting somatic nerves to the external urethral sphincter inhibiting parasympathetic stimulation of the detrusor muscle D inhibiting sympathetic stimulation of the internal urethral sphincter E) stimulating somatic nerves to the external urethral sphincterarrow_forward
