Document Summary
Lecture 19 renal system: anatomy and cellular physiology. Renin (an enzyme that generates the precursor of angiotensin ii, which influences. The nephron is the functional unit of the kidney. The glomerulus is the site of blood filtration. Extrinsic regulation of gfr: neural and hormonal control. Vasoconstriction of the e fferent artiole ( a fferent artiole remains unchanged) would increase hydrostatic pressure in the glomerular capillaries and increase glomerular filtration rate (gfr). a) true b) false. Principles governing the tubular reabsorption of water and solutes. Used by substances that have to be moved against their concentration (or electrochemical) gradient; requires atp hydrolysis (e. g. na + /k + -atpase). A concentration gradient is established for one substance (e. g. na + ) in a process that requires atp hydrolysis(e. g. na + /k + -atpase). The concentration gradient is then used to transport another substance (e. g. glucose) against its concentration gradient. Used by substances that move down a concentration gradient.
