Renal Overview Flashcards
1
Q
the kidney is subject to regulation by
A
- hormones
- autonomic nervous system
2
Q
what does the interlobular artery feed into
A
- afferent arteriole
3
Q
what is the vasa recta
A
- specialized peritubular capillaries
4
Q
most renal blood flow occurs in the
A
- cortex
5
Q
components of the glomerulus
A
- glomerular capillaries
- Bowman’s capsule
6
Q
main purpose of Bowman’s capsule
A
- filtration of plasma into Bowman’s space
7
Q
role of proximal tubule
A
- reabsorbs all glucose and amino acids, bicarb, ions, and water, and 50% of urea
- secretes H+ and some drugs, pollutants, and para-amino hippurate
8
Q
role of loop of henle
A
- creates hyperosmotic medullary interstitium
- separates reabsorption of water from reabsorption of solutes
- important for concentrating urine
9
Q
role of early distal tubule
A
- dilute urine
- further reabsorption of Na+ causes additional dilution of forming urine
10
Q
role of late distal tubule/collecting duct
A
- hormones fine tune ion and water reabsorption
11
Q
which hormones fine tune ion and water reabsorption
A
- ADH
- aldosterone
- ANP
12
Q
osmolality of tubular fluid in proximal tubule
A
- isosmotic
13
Q
osmolality of tubular fluid in loop of henle - enters how
A
- enters isosmotic
14
Q
osmolality of tubular fluid in loop of henle - bend of the loop of Henle is
A
- hyperosmotic
15
Q
osmolality of tubular fluid in loop of henle - exits
A
- hypo-osmotic
