Which is an example of a substance that can be excreted by glandular activity?

Breast milk
Feces
Saliva
Urine

The correct answer is: Saliva

Saliva is an example of a substance that can be excreted by glandular activity because it is produced and secreted by the salivary glands in the mouth. Saliva plays a crucial role in the initial stages of digestion by moistening food and beginning the process of breaking down carbohydrates. Breast milk is not excreted but rather secreted by the mammary glands to provide nutrition to an infant. Feces are a byproduct of digestion and are excreted through the rectum. Urine is the waste product excreted by the kidneys through the urinary system.
