126)Given a GFR of 100 mL/min, and a plasma concentration of solute of 10 mg/mL, what is the filteredload of this solute?126)
A)1000 mL/minB)100 mg/mLC)100 mg/dLD)1 g/mLE)1000 mg/min127)When carrier proteins are saturated, they are said to be working at what?127)
128)The clearance of ________ provides a measure of renal plasma flow rate.128)
129)The clearance of what substance, which is not produced in the body but must be injected, providesa measure of glomerular filtration rate?129)
130)The clearance of what substance, a natural by-product of muscle metabolism, provides anon-invasive estimate of glomerular filtration rate?130)
131)In terms of controlling micturition, the somatic nervous system innervates the ________, theparasympathetic nervous system innervates the ________, and the sympathetic nervous systeminnervates the ________.131)
132)The micturition reflex is activated by the stretch of the bladder, which activates what?
132)A)sympathetic afferentsB)somatic afferentsC)parasympathetic afferentsD)stretch receptorsE)parasympathetic efferentsTRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false.133)
The excretion of water and solutes in urine has a significant impact on the volume and compositionof fluids in the body.133)134)The kidneys receive only a small proportion (1%) of cardiac output at rest.
134)135)Bowman's capsule consists of the renal corpuscle and glomerulus.135)136)The proximal tubule is connected to the thick ascending limb of the loop of Henle.136)137)The connecting tubules join the distal tubule with the collecting ducts.
137)138)The macula densa consists of specialized cells of the distal tubule epithelium.138)139)Juxtaglomerular cells are located in the walls of the distal tubule.139)140)The vasa recta are in series with the glomerulus.140)141)Glomerular filtration involves the bulk flow of plasma (with all of its solutes) into Bowman's space.
141)142)The glomerular capillaries are composed of a fenestrated surface that allows protein-free plasma toexit the vasculature.142)143)Glomerular capillary hydrostatic pressure is greater than systemic capillary hydrostatic pressure.143)144)Bowman's capsule hydrostatic pressure is greater than systemic interstitial fluid hydrostaticpressure.
