Document Summary
The kidney is quite complex a complex organ, which is involved in many different functions important for homeostasis (know these). Each kidney is approximately the size of your fist and can actually filter 180 l of fluid a day! This is pretty impressive for two organs that are fairly small. Maybe even more interestingly, we can actually lose almost of our kidney function and still live - which is why it"s possible to donate a kidney. By the end of this section, you should be able to: Describe homeostasis as it applies to body fluids and osmolarity. o. Describe blood flow in the kidneys: blood flows into the renal artery many arcuate arteries interlobular artery afferent arteriole glomerulus efferent arteriole peritubular capillaries interlobular vein renal vein. L/day: amount reabsorbed = filtered load amount excreted, fraction excreted = (amount excreted/ filtered load) x 100%
