Chemical digestion begins first in which organ?

Explanation:
Chemical digestion begins in the mouth because saliva brings enzymes that start breaking down food as you chew. The main player is salivary amylase, which starts converting starches into simpler sugars right there in the mouth. There’s also a small amount of lipase in saliva that begins fat digestion, though its contribution is minor. Chewing with saliva forms a bolus ready to swallow, kickstarting the digestive process. The stomach then continues digestion with acid and enzymes, and most digestion and absorption occur later in the small intestine, but the first enzymatic breakdown happens in the mouth.
