6. CARDIAC and RENAL: Nephron activity Flashcards
24.1, 24.2, 24.3, 24.4
k
What structure does the work of the kidney?
the nephron
draw and label a nephron
Numeral VI
WHere does reabsorption of sodium chloride happen?
ascending loop of Henle
Where does pressure driven size dependent filtration happen
proximal convoluted tubule
where does hormone dependent reabsorptiom or secretion happen
distal convoluted tubule
where does reabsorption of water heppen
descending loop of hele
How much water gets reabsobed in proximal conv tubule? GLUCOSE? sodium? amino acids? cells? Fats
23 water, 100% glucose, 2/3 sodium, 99% amino acids, zero cells, zero fats (they attach to proteins)
How much flitrate escapes the prox conv tubule?
1/3
What activates the 3 nephron transporters?
PTH, aldosterone, ADH
PTH transporter does this
reabsorbes calcium if activated
aldosterone activation makes what start?
the sodium and potassium transporter- 2 way transporter
ADH transporter does this when activated
reabsorbs more water
