THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The stomach is a muscular hollow organ. It takes in food from the esophagus (gullet or food pipe), mixes it, breaks it down, and then passes it on to the small intestine in small portions. The entire digestive system is made up of one muscular tube extending from the mouth to the anus.

Detailed explanation-2: -Why is digestion important? Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.

Detailed explanation-3: -Answer: false, complete digestion takes place in small intestine. The small intestine carries out most of the digestive process, absorbing almost all of the nutrients you get from foods into your bloodstream.
