The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tongue, salivary glands, pancreas, liver, and gallbladder).Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body. The food material is initially torn into pieces by the chelate legs and powerful mandibles and passes into the oesophagus whence it is transported to the cardiac part of the foregut. By releasing zymogens instead of the active enzymes chymotrypsin and trypsin, the pancreas avoids self-digestion. 1 Answer.

The enteric nervous system will later address the complexity of neurotransmitters as well as intra and extracellular mechanisms. They release zymogens outside the cell and into the body by a process called exocytosis. The midgut is composed of a long straight tube which often contains blind pouches (caeca). • Match input with output. The vertebrate digestive system is designed to facilitate the transformation of food matter into the nutrient components that sustain organisms. It develops from the endoderm germ layer during embryogenesis. Sucrase is an enzyme that breaks down disaccharide sucrose, commonly known as table sugar, cane sugar, or beet sugar.
