What component of a cell functions like the digestive system in human body?

The lysosome is the component of a cell that functions like the digestive system in the human body. Lysosomes are small organelles that contain digestive enzymes that break down various materials, such as food particles, worn-out cell parts, and foreign invaders. They are analogous to the human digestive system in that they break down complex substances into simpler components that can be used by the cell.
