Detailed explanation-1: -Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair.

Detailed explanation-2: -Lysosomes. Closely related to the Golgi apparatus are lysosomes. These membrane-bound organelles are the sites where most intracellular digestion occurs.

Detailed explanation-3: -The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change. Specialized cells help absorbed materials cross the intestinal lining into the bloodstream.

Detailed explanation-4: -The digestive system is made up of the gastrointestinal tract-also called the GI tract or digestive tract-and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.
