The Pharynx leads from the mouth to the esophagus and then down to the digestive tract.

The liver and pancreas are two important organs that lie outside the digestive tube but play crucial roles in the digestive process. The liver produces bile, which helps emulsify fats for better digestion and absorption. The pancreas secretes digestive enzymes into the small intestine to break down carbohydrates, proteins, and fats.
Lysosomes, they are the disposal system of the cell.
The stomach is a stretchy muscular sac that holds food where it mixes with digestive juices. It plays a key role in the digestion process by breaking down food into smaller particles that can be absorbed by the body.
A complete digestive tract, also known as a tube-within-a-tube system, features a separate mouth and anus, allowing for a more efficient and continuous flow of food and waste. In contrast, a sac-like digestive tract, found in organisms like jellyfish, has only one opening that serves as both mouth and anus, leading to a less efficient digestion process where food and waste can mix. This structural difference impacts nutrient absorption and the overall efficiency of digestion.

A lysosome is a sac of digestive enzymes, used to break down monosaccharaides and disaccharides. Lysosomes are found in animal cells and are also called suicide sacs.

A sac filled with digestive chemicals would likely belong to an organism with a type of digestive system where digestion occurs externally. Examples include certain insects like beetles and spiders that use their digestive sacs to break down and pre-digest food before consuming it. The chemicals in the sac help to breakdown food particles into smaller, more digestible components.
