Tubular reabsorption
Basic Renal Process - Tubular secretion
From blood to tubule
Descripe the Renal Process in 3-4 sentences
1) Glomerular filtration: Nondiscriminative filtration of a protein-free plasma from the glamorous into Bowmans capsule
2) Tubular reabsorption - Selective movement of filtered substances from the tubular lumen into the peritubular capillaries
3) Selective movement of on filtered substances from the pertibular capillaries into the tubular lumen
