Document Summary
Kidneys filter blood via nephron, each nephron is involved. Blood filters into the kidney multiple times, gets shit done. Know how blood is supplied/removed from the nephron. Filtration always occurs from glomerular capillaries to the bowman"s capsule, unidirectional. Each nephron has its own system of tubules. Whatever is left over from collecting duct is excreted. All nephron"s renal corpuscles are located in the cortex, and loops go through the medulla. Know the order of blood flow to the kidney. Know the order of where the filtrate travels to (the tubule sections) Know the barriers of filtration podocytes, endothelial cells, basal lamina they prevent large macromolecules from being filtered. Main component of blood being filtered is plasma no blood cells. Know the compounds that can be filtered, which purifies the blood and maintaining certain levels. Majority of water reabsorbed is in the proximal tubule, as is most of the glucose. Calculate net filtration pressure and what each force favors and represents.
