BIO 1 Flashcards
Human plasma osmolarity levels (normal)?
300mOsm, or .3 Osm (1 osmole=1mole)
What is high concentration in the cell?
K+ and PO4(3-)
What is high concentration outside the cell?
Na+ Ca(2+) Cl- Mg(2+)
what is mainly extracellular fluid?
blood (plasma)
Osmolarity is constant throughout cell and extracell
Just a fact there…
albumin
blood protein
albumin serum
blood
Interstitial Fluid
Makes up most of EC fluid, mainly water
Plasma
Other part of EC fluid
Functions of Kidney: Filtration
Makes sure no blood gets in system
FoK: Secretion
Gets rid of good ions and reabsorbs them back into the blood stream (urea stays)
Nephron
Blood pressuring system in kidney
Filtration Pressure (See Slide)
Bowman’s Capsule->Nephron (filtrate)
Cells? Blood? Albumin? Proteins?
No, it does not make it in
Bowman’s Capsule->Nephron (filtrate)
Ions? Glucose?
Yes, they make it in.
Glucose in urine? Whats going on?
Anything too much in urine?
Definetely had too much glucose in blood
Too much in blood!
ADH
regulates water in blood
Kidney Diagram (See)
Vasa Recta
Runs countercurrent to nephron in order to keep salt and water flowing out of nephron
