Appu has constipation (difficulty in passing stools) and the stools (excreta) that he passes with great difficulty are very dry. The doctor advises him to take a laxative known as milk of magnesia, which will allow Appu to pass stools easily.
On which of the following organs do you think that the laxative primarily acts?
Intestines
The laxative acts on the intestines, particularly the large intestine. It allows smooth passage of stools and makes the stool retain more water in the large intestine. This relieves constipation allowing Appu to pass stools easily.
