Anatomy and Physiology
- Which glomerular arteriole is larger, and why? the efferent, because it increases hydrostatic pressure in the glomerulus the efferent, because it increases colloid oncotic pressure in the glomerulus the afferent, because it increases hydrostatic pressure in the glomerulus the afferent, because it increases colloid oncotic pressure in the glomerulusarrow_forwardThe fenestrations of the glomerular capillaries allow all blood components except blood cells to pass through True Falsearrow_forwardexample of the fundamental concept of glomerulus.arrow_forward
- Is 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_forwardIs 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_forwardWhat 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_forward
