Renal System Flashcards
What do kidneys do with the blood they receive from the heart?
They filter it
Kidneys function to
- Regulate pH of the blood
- Collect + maintain nutrients
They kidney has two capillary beds which work together to
Deliver oxygen and collect nutrients
What are the two capillary beds of the kidney?
- Vasa Recta
- Peritubular Capillaries
The Vasa Recta functions to
Give O2 to kidneys
The Peritubular Capillaries function to
Collect nutrients which the kidney will filter
Blood enters kidney via the
Renal artery
Renal medulla is very salty due to
Ion absorption
The Nephron is situated between the
Renal cortex and renal medulla
The Renal Pelvis is where all the
Renal Calyx collect
Urine from the renal pelvis leaves via
Ureters
What is the Bowman’s Capsule?
First part of the nephron that collects filtrate to form urine
The Proximal Convoluted Tube reabsorbs
- Na+ and Cl-
- AAs
- Glucose
- H2O
What are the two limbs of the Loop of Henle?
- Descending
- Ascending
The Descending limb functions to
Absorb water passively
The Ascending limb functions to
Reabsorbs Na+, Cl-, and K+ actively
Which limb of the Loop of Henle is impermeable to water?
Ascending limb
The Distal Convoluted Tube loops back and
Kisses the glomerulus
The Distal Convoluted Tube allows for
Reabsorption of other ions + picks up important nutrients
When Distal is in contact with the glomerulus, there is the formation of the
Juxtaglomerular Apparatus
The Juxtaglomerular Apparatus functions to
Control blood pressure
The Collecting Duct functions to
Collect leftover fluid in the lumen + reabsorb any water or urea
