Physiology Review Slides Lec. 15 Flashcards
Hoe many nephrons are in a single Kidney?
800k - 1 million nephrons
What happens to the EC volume of the cell when there is a Net GAIN of fluid by the body?
The Volume will ALWAYS Enlarge
Juxtamedullary nephrons
- Have glomeruli DEEP in the Cortex or Near MEDULLA
- Have LONG loops of Henle
- Have long EFFERENT Arterioles associated w/ Peritubular capillaries
(VASA Recta)
Another name for Vasa Rects is ______.
Peritubular capillaries
Each Collecting Duct receives urine from _____ nephrons.
4000
Osmolar Gap
The Diff b/w the MEASURED OsmolaLity and the ESTIMATED OsmolaLity
- Normal less that or equal to 15
What % the total nephrons are Juxtamedullary nephrons?
20 - 30%
How many Collecting ducts are in each Kidney?
~ 250
T/F: The nephrons in the body decrease by 10% every year after the age of 40
True
How much body fluid is Interstitial fluid?
~11 liters
Cortical Nephrons
- Have glomeruli locates in the OUTER Cortex
- Have SHORT loops of Henle
How much body fluid is Plasma fluid?
~ 3 liters
Kidney receives about what percentage of Total Cardiac Output?
- 22%
- 1100ml/min
BMP
Basic Metabolic Profile
What does LOW Hydrostatic Pressure in Peritubular capillaries do?
Permits Rapid fluid REABSORPTION
What does HIGH Hydrostatic Pressure in Glomerular capillaries do?
Causes Rapid FILTRATION
Common things to ELVATE the Osmolar gap?

- Methanol
- Ethanol
- Mannitol
- Ethylene glycol
“ A MEME”
How much of your bodily fluids is INTRACELLULAR?
- 40%
- 28L
What helps to regulate hydrostatic pressure in BOTH Glomerular and Peritubular capillaries
EFFERENT Arterioles
