What would be the correct response of the myogenic mechanism to regulate
glomerular filtration rate (GFR) in cases of overhydration?
Put these events in order (1: start; 6: end; select "not relevant" when appropriate)
V
V
Decreased blood volume
reaches the glomerulus
Glomerular hydrostatic
pressure increases back to
normal
Intrarenal baroreceptors
activity increases
Increased blood volume
reaches the glomerulus
Intrarenal baroreceptors
activity decreases
Intrarenal baroreceptors
activity decreases
Glomerular hydrostatic
pressure decreases back to
normal
Blood volume and mean
arterial pressure increase
Smooth muscles relax and
afferent arterioles dilate
Stretch-sensitive
Ca2+ channels open and
allow calcium influx into the
smooth muscle cells lining
the afferent arterioles
Smooth muscles contract
and afferent arterioles
constrict
