Sympathetic stimulation causes granular cells to release renin, which ultimately leads to mesangial cell contraction and is denoted as option C.
<h3>What is
Sympathetic stimulation?</h3>
This is referred to as the process in which the sympathetic nervous system is stimulated so as to enable certain types of activities such as heart and digestive rate to be adequately performed by the body for its survival.
In the digestive system, its stimulation results in granular cells releasing renin, which ultimately leads to mesangial cell contraction. This is responsible for the coagulation which occurs in the stomach.
Digestion of the milk is enhanced in this process especilly in young children and is therefore the reason why option C was chosen as the most appropriate choice.
