ANTOMY AND PHYSIOLOGY
- Renal is a process that yields relatively constant GFR with fluctuating blood pressure in the kidney, occurring through (two words) where the smooth muscle of the afferent arteriole constricts when stretched and a tubuloglomerular feedback mechanism which occurs when the are activated by rising NaCl concentrations and increased flow rates.arrow_forwardexample of the fundamental concept of glomerulus.arrow_forwardThe fenestrations of the glomerular capillaries allow all blood components except blood cells to pass through True Falsearrow_forward
- Is this statement true or false: The juxtagomerular apparatus also pays a role in controlling the net glomerular filtration rate. If the GFR is high macula densa cells detect increase blood pressure. These cells respond by decreasing releasing of water which results in vasoconstriction of afferent. This decreases the GFR.arrow_forwardIs this following statement correct? In the kidney, vasoconstriction of the afferent arteriole increases glomerular filtration rate, because hydrostatic pressure in the glomerular capillaries increases (much like putting your thumb over the end of a garden hose increases the pressure and causes the water to exit the hose with greater velocity and travel a greater distance).arrow_forwardphysiology of micturition and the use of sphincters. (simple and easy and in own words) dot pointsarrow_forward
- What is the effect of atrial natriuretic peptide on the glomerular filtration rate? vasoconstricts the afferent arteriole, decreasing the GFR vasoconstricts the afferent arterioe. increasing the GFR vasodilates the afferent arteriole, decreasing the GFR vasodilates the afferent arteriole, increasing the GFRarrow_forwardOnly two types of tubules enter the renal medulla, the loop of Henle and the (?????) which further concentrates the filtrate as it heads for the renal pelvis.arrow_forwardFiltration is always favored in the glomerular capillaries because the sum of the Starling forces that favor reabsorption is zero.
