Renal corpuscle
glomerulus and bowmans capsule
Glomerulus
like pasta strainer, keeps blood cells lets filtraite escape
Efferent artiriole
blood out, smaller
Afferent arteriole
blood in, thicker
Filtrate
excess liquid aka blood plasma
Filtrate contains
Water, electrolytes, glucose, amino acids, bicarbonate, creatinine, urea
Urea (BUN)
makes pee yellow
What is not that important to keep in filtrate
creatinine and urea
PCT
what is reabsorbed, water Electrolytes Amino acids Bicarbonate Glucose
Job of nephron
get important things back
Co transpoter
Antiporter and synporter
Antiporter
2 things going oppisite direction ie sodium pottasium pump
Synporter
Things going in same direction
SGLT2
Only lets Na in with glucose
Glut2
Always open glucose channel
Na K pump
makes it so there is more k in the cell than out the cell
What should the amount of glucose in blood equal
the amount of glucose in filtrate
What happens when blood sugar is 200mg or less
kidneys get 100% of it back
What is the MAX amount of blood sugars kidneys can reabsorb
400mg; excess doesnt get absobed and passed loop of henely/ appers in urine
Loop of Henle
where water and salt are absorbed
Osmalarity
how much stuff is in water
Where is h20 absorbed in LOH
the decending limp of LOH
Where is the most water in LOH
Top of descending limb of LOH
What is at the botton of LOH
laest amount of water but most amount of salt
Where is salt absorbed in LOH
ascending limb of LOH
Vasa Recta
capilary wrapped around LOH, gutter basically, excess salt and water rejoin blood here
Polyuria
excess peeing
Osmoric Diueresis
peeing too much due to glucose
Polydipsia
excessive thirst
How does eating too much sugar affect LOH
excess glucose causes too much osmalarity causing you to pee more
How does Na K pump fuction
its is active and uses atp
What role do kidneys play in ph
DCT gets rid of excess hyrdogen
