How could the fluid that passes through, the proximal convoluted
tubule, the loop of Henle, the distal convoluted tubule and the
collecting conductors be?
Indicate the functions of the proximal convoluted tubule, the
loop of Henle, the distal convoluted tubule, and the collecting
ducts and how is the fluid passes through each one.
21. Bicarbonate is reabsorbed into the epithelial cells of the
proximal convoluted tubule as ________________.
HCO3-
CO2
H2CO3
Carbonic anhydrase
22. Loop diuretics block the Na+/ 2Cl-/K+ cotransporter on the
ascending loop of henle. How does this reduce water
reabsorption?
By preventing the reabsorption of sodium ions, water is not
reabsorbed from the ascending loop of henle
It causes hyperkalcemia which stimulates Aldosterone secretion,
thereby, indirectly causing the excretion of sodium, potassium and
water.
It abolishes and/or reduces the osmotic...
Osmotic movement of water by proximal convoluted tubule cells is
referred to as ______ (three words), whereas _____ (three words) is
when water is reclaimed from filtrate in the collecting duct.
Q.The cells lining the proximal convoluted tubule have numerous
microvilli and mitochondria. What is the implication of
the presence of such structures and organelles?
a. Rapid osmosis occurs in the proximal
convoluted tubule.
b. Energy-dependent active transport occurs in
the proximal convoluted tubule.
c. The proximal convoluted tubule is the site
of water conservation.
d. The proximal convoluted tubule is important
in the storage of salts.
e. The production of urea requires a large
amount of ATP.
Q. Which part of...
When propeller passes fluid through it as in the case of the
propeller on a boat. List what you would use to calculate the work
done for the following:
1. The work done by the propeller
2. The work done by the flow of water
1) What happens first in response to fluid loss in the ECF
(e.g., dehydration)? What
happens next?
2) What is tubular deamination and how can it help correct
problems with acid/base
balance?
