Part 2 Flashcards
GFR is equal to?
RBF x FF
RBF is equal to?
GFR/FF
FF is equal to?
GFR/RBF
To increase GFR there has to be an increase in the overall cadiac output and dilate afferent arterioles in the kidney by altering?
Renal Plasma Flow
When contracting efferent arterioles increase glomerular pressure by altering?
Filtration Fraction
What are the 3 layers of glomerular capillary membrane?
- Endothelium
- Basement Membrane
- Epithelial Cell Layer (podocytes)
The proportion of the fluid reaching the kidneys which passes into the renal tubules is known as the?
Filtration Fraction
Urine filtrate should contain?
Water and Salt
Urine filtrate should not contain?
Protein and Blood
Renal blood supply has unique blood flow of 2 capillary beds which are separated by?
Efferent Arterioles
What constricts efferent arterioles?
Epinepherine
Norepinepherine
Renin
Efferent arterioles are highly sensitive to?
Angiotensin II
Where does sodium get reabsorbed?
In the Proximal tubule
The greater the concentration of Na+ in the proximal tubule the greater the?
Reabsorption Rate
Water and sodium is reabsorbed in the?
Proximal Tubule
Kidney damage is the result in the release of?
Excess Protein
Impaired sodium excretion can cause?
Kidney Damage
Kidney damage leads to electrolyte and fluid imbalance which can cause cardiac insufficiency which can cause?
Death within days
What are specialized epithelial cells in late distal and collecting tubules that secrete potassium for excretion?
Principal Cells
Principal cells secrete potassium for excretion and are stimulated by?
Aldosterone
