urine volume decreased
answer
What happened to the urine concentration as the solute concentration in the interstitial space was increased?
question
the concentration of the urine increased
answer
What happened to the volume of urine as the solute concentration in the interstitial space was increased?
question
urine volume will increase in the absence of ADH in the collecting duct
answer
What do you think would happen to urine volume if you did not add ADH to the collecting duct?
question
reabsorbed to prevent fluid loss and maintain homeostasis
answer
Is the most of the tubule filtrate absorbed into the body or excreted in urine?
question
yes, the reabsorption of solutes affects water reabsorption because water will follow the solutes by osmosis
answer
Can the reabsorption of solutes influence water reabsorption from the tubule fluid?
question
the glucose concentration in the bladder decreased
answer
What happens to the concentration of glucose in the urinary bladder as the number of glucose carriers increases?
question
secondary active transport; facilitated diffusion along the basolateral membrane
answer
What types of transport are utilized during glucose reabsorption and where do they occur?
question
when the number of glucose carriers becomes great enough all of the glucose is reabsorbed.
answer
Why does the glucose concentration in the urinary bladder become zero in these experiments?
question
excess glucose in the blood so the carriers can reach their maximum transport levels
answer
A person with type 1 diabetes cannot make insulin in the pancreas, and a person with untreated type 2 diabetes does not respond to the insulin that is made in the pancreas. In either case, why would you expect to find glucose in the person's urine?
question
addition of the aldosterone, urine volume decreased
answer
How did the addition of aldosterone affect urine volume?
question
Aldosterone results in increased sodium and water reabsorption and increased potassium secretion
answer
Can the reabsorption of solutes influences water reabsorption in the nephron?
question
urine volume decreased
answer
How did the addition of ADH affect urine volume?
question
potassium was more concentrated because the volume of urine decreased
answer
Why did the addition of ADH also affect the concentration of potassium in the urine?
question
stimulated by production of angiotensin II, which is under control of the body's renin-angiotensin system
answer
What is the principle determinant for the release of aldosterone from the adrenal cortex?
