Renal system, part two Flashcards
1
Q
obligative water reabsorption is
A
water reabsorbed by osmosis
2
Q
facilitative water reabsorption is
A
water is reabsorbed selectively - regulated by ADH in the collecting duct
3
Q
What does ADH stand for
A
Antidriuretic hormone
4
Q
Aquaporins are transmembrane proteins which
A
aid water reabsorption
5
Q
Osmolality is the….
A
number of solute particles dissolved. This reflects the solutions ability to cause osmosis
6
Q
A high osmolality =
A
a lot of solute particles dissolved thus a high sodium concentration thus a low water concentration
7
Q
ADH helps regulate
A
water concentration
8
Q
what do ureters do?
A
transport urine to the bladder by means of peristalsis
9
Q
what does the urethra do?
A
transport urine to the outside
10
Q
