Verified step by step guidance

Understand the role of the afferent and efferent arterioles in regulating glomerular capillary pressure. The afferent arteriole brings blood to the glomerulus, while the efferent arteriole carries blood away.

Recognize that dilation of the afferent arteriole increases blood flow into the glomerulus, thereby increasing glomerular capillary pressure.

Identify that increased systemic blood pressure generally increases glomerular capillary pressure as more blood is pushed into the glomerulus.

Understand that constriction of the efferent arteriole increases glomerular capillary pressure by creating a backup of blood in the glomerulus.

Conclude that constriction of the afferent arteriole decreases glomerular capillary pressure by reducing the amount of blood entering the glomerulus, thus lowering the pressure.
