Which excretion route is an example of glandular activity?

Feces
Saliva
Urine
Renal

The correct answer is: Saliva

Saliva is an example of glandular activity because it is produced by the salivary glands in the mouth. Saliva plays a crucial role in digestion by moistening food, helping to break it down, and beginning the process of chemical digestion through the action of enzymes like amylase. In contrast, feces are the waste products of digestion that are eliminated through the rectum and anus, urine is produced by the kidneys as a waste product of metabolism and excreted through the urinary system, and renal refers to processes related to the kidneys.
