glomerulus filtration, tubular reabsorption, and tubular secretion
what is the term for when blood pressure forces plasma through glomerular sieve. And the filtrate excludes blood cells, proteins, and little factors?
glomerular filtration
what is the term for when valve molecules/ions move from tubule to the peritubular capillaries?
tubular reabsorption
where do the litter factors go during glomerular filtration?
renal tubule
