Question:
Glomerular filtration
Answer:
-Water
-Most solutes in blood plasma > wall of the glomerular capillaries >
glomerular capsule (renal corpuscle) > renal tubule too form filtrate

,Question:
Glomerular blood hydrostatic pressure
Answer:
BP in glomerular capillaries that forces water and solutes through filtration
slits




Question:
Capsular hydrostatic pressure
Answer:
Exerted against filtration membrane by fluid in capsular space




Question:
Blood colloid osmotic pressure
Answer:
Pressure due to presence of proteins in blood plasma that oppose filtration

, Question:
Tubular reabsorption
Answer:
-99% water
-Vital solutes reabsorbed
-Return to blood through peritubular capillaries and vasa recta
-Water passively reabsorbed




Question:
Tubular secretion
Answer:
-Wastes, drugs & excess ions removed from the blood, added to filtrate, and
excreted from the body as urine




Question:
GFR regulation: Renal autoregulation
Answer:
Myogenic & tubuloglomerular feedback
