2.) What type of filtrate will stimulate the macula densa cells to increase the diameter of the afferent arteriole? What type of filtrate would require an increase in filtration rate?2.) What type of filtrate will stimulate the macula densa cells to increase the diameter of the afferent arteriole? What type of filtrate would require an increase in filtration rate?

Solution

2) Filtrate with low concentration of sodium chloride will stimulate the macula densa cells to increase the diameter of the afferent arteriole.

This leads to increase in blood flow to glomerulus and glomerular filtration rate.

Therefore, filtrate with low concentration of sodium chloride would require an increase in the filtration rate
