Final part of the ascending loop of Henle makes contact with the __________ arteriole serving that renal corpuscle.This region is known as the ______________.
a hollow, distensible muscular organ with a capacity of about 700-800mL.
When volume increases, stretch receptors send signals to a micturition center in the ____________ triggering the micturition reflex.
the movement of waste materials from the body to the filtrate
two molecules collectively together into a cell
two molecules - one comes in and one comes out
Reabsorption of fluids, ions, and other substances occurs by _______ and ______ means
Modified smooth muscle cells with phagocytic properties
potent vasoconstrictor of both afferent and efferent arterioles (reduces GFR)
possible because the renal blood vessels are supplied by sympathetic ANS fibers that release norepinephrine causing vasoconstriction
Pressure and flow monitored in the macula densa provides feedback to the glomerulus
Normally ______ Starling forces are at work in glomerular filtration
Filtration is controlled by 2 opposing ___________ forces and 2 opposing __________ forces at the glomerular membrane called ____________ forces.
secreted by cells in the atria; a sudden large increase in BP stretches the cardiac atria and releases ________; causes the glomerular capillaries to relax, increasing the surface area for filtration (increases GFR)
process of returning important substances from the filtrate back into the renal interstitium, then into the renal blood vessels...and back into the body
Stretching in the glomerular capillaries triggers contraction of smooth muscle cells in afferent arterioles (reduces GFR)
passive process that occurs between adjacent tubule cells (tight junctions do not completely seal off interstitial fluid from tubule fluid)
At rest, sympathetic stimulation in the kidneys is ______.
GFR avg. for males = _____________; GFR avg. for females = ____________
smooth muscle around the afferent arterioles have plentiful _______ receptors which bind norepinephrine and cause the muscle fibers to ________.
