Digestion starts in man from

A. Rectum

B. Stomach

C. Mouth

D. Intestine

Answer: Option C

Solution(By Examveda Team)

An adult's digestive tract is about 30 feet (about 9 meters) long. Digestion begins in the mouth, well before food reaches the stomach. When we see, smell, taste, or even imagine a tasty meal, our salivary glands in front of the ear, under the tongue, and near the lower jaw begin making saliva (spit).
