Unformatted text preview: slide Kidneys filter blood and then reabsorb what it needs. Vaso recta very important. Specialization associated with the renal corpuscle (glomerulus and bowmans capsule) Distal tubule releases paracrine agents that regulate glomerular filtration. Juxtaglomerular apparatus cells secrete renin. Initial filtration into bowmans space has exact composition of plasma except for protein. Ultra filtrate of plasma minus protein (everything in blood has been filtered). Everything needed is recovered (Na+, water) potassium ion is secretedYou have filtration secretion and excretion.
