True or False? Dilation of the afferent arteriole would increase glomerular pressure.Group startsTrue or FalseTrue, unselectedFalse

Step 1: Break Down the Problem

To determine whether the dilation of the afferent arteriole increases glomerular pressure, we must understand the role of the afferent arteriole in the kidney.

Step 2: Relevant Concepts

• The afferent arteriole is responsible for supplying blood to the glomerulus in the kidney.
• Dilation of the afferent arteriole allows more blood to enter the glomerulus, which is likely to increase the pressure within the glomerular capillaries.
• The glomerular filtration pressure is influenced by the resistance of the afferent and efferent arterioles; dilation of the afferent arteriole reduces resistance, thereby increasing pressure.

Step 3: Analysis and Detail

• When the afferent arteriole dilates, it reduces the vascular resistance entering the glomerulus.
• This results in an increased blood flow into the glomerulus, effectively increasing glomerular capillary pressure.

Step 4: Verify and Summarize

Based on the physiological principles of renal blood flow and pressure dynamics, the statement can be verified:

Dilation of the afferent arteriole indeed increases glomerular pressure due to enhanced renal blood flow.

Final Answer

True. Dilation of the afferent arteriole would increase glomerular pressure.
