Group of answer choices

it increases

it decreases

it stays constant

all of the above

22. Water reenters circulation through which of the following structures within
the nephron during reabsorption?

Group of answer choices

peritubular capillary network

interstitium

lymphatic capillary

none of the above

20. Which product of fermentation (in the colon) can be used to make ATP
in humans?

Group of answer choices

carbon dioxide

methane gas

volatile fatty acids

all of the above

Answer 1

25. It's forced convection.

As the wind blows or by the flowing water the fluid exchange takes place. It's an example of forced convection.

23. It decreases.

Blood pressure inside the glomerulus is the primary driving force for the glomerular giltrate formation. So as pressure drops filtration too decreases.

22. None of the above.

The water enter the circulation by the reabsorption process in the nephrons. This occurs mainly through the proximal tubule. It also enters through the collectinf duct. This is transported back by the Vasa recta.

20. Volatile fatty acids.

They are transported to the liver. Where they can be used for the ATP production.
