Question

I need help with #1 and #3 A, B, and C please

L. Ms. W has just eaten a large bag of salty popcorn. Her blood is now too salty and must be diluted. Is it possible for the kidney to increase water reabsorption without increasing salt absorption? Explain. 2. Mr. R is taking penicillin to cure a throat infection. He must take the drug frequently beca the kidney clears penicillin very efficiently. That is, all of the penicillin that enters the ren artery leaves the kidney in the urine. However, only some penicillin molecules will be filt into the glomerular capsule. How can the kidney excrete all of the penicillin it receives? P0:395 3. Ms. J is stranded on a desert island with limited water supplies A. How will the volume and concentration of her body fluids change? B. How will her hypothalamus and pituitary gland respond to these changes? C. What will be the net effect of these responses?

Answer 1

1. The blood salts are filtered by glomurelus of kidney into proximal convulated tubules and then these salts are reabsorbed by various process back into blood stream and cells

No it is not possible for kidney to reabsorb maximum water reabsortion without salt absorption because salt reabsorption increases passive water reabsorption, meaning that when sodium reabsorbs water also enters The movement of water balances maintains the osmotic pressure within or across the tubule walls

3 (A)

there is a marked change in the fluids volume and concentration in desserts the volume body fluid concentration of salts decreased due to sweating and having limited sources of fluid in desserts

B .

Hypothalamus and pituary gland maintains water and salt balance in the body by homeostasis. It will respond to kidney a that less urine will pass out from the body.

C.

The total response is that water and salt concentration decreases which also decreases urine output which makes a person more lethargic feeling tired and physiology of body gets disturbed
