BIO310H5 Lecture Notes - Lecture 12: Renal Function, Efferent Arteriole, Myogenic Mechanism
Document Summary
Kidney will only take what needs, rest will be lost: glomerulus filtration rate, regulation of the amount of the filtrate, how much of the ultra filtrate will be filtrate, ex. Amount of blood going into the glomerulus: can divide into. Intrinsic: within kidney, ultra regulation, myogenic mechanism the wall of the efferent arterioles are where the smooth muscles are. The smooth muscles are able to contract and relax in response to main factor. If blood pressure is low, will contract to maintain. In order to increase peripheral resistance increase pressure of the fluid exerts on. Smooth muscle will relax in order to reduce blood pressure: extrinsic, can increase rate or decrease rate of glomerulus filtration rate. Intrinsic how kidney will control glomerular flirtation rate: extrinsic through sympathetic nervous system activity. Sympathetic exerts its effects on peripheral blood vessels and system of circulation. Stimulation of sns will produce monoconstriction or dilation.
