What are Three things that help in digestion?

Three things that help in digestion are:

1. Enzymes: Enzymes are proteins that act as catalysts for chemical reactions in the body. They help break down complex food molecules into simpler ones that can be absorbed by the body. Different enzymes are responsible for digesting different types of food, such as carbohydrates, proteins, and fats.

2. Gastric juices: Gastric juices are produced by the stomach and contain hydrochloric acid and enzymes such as pepsin and lipase. Hydrochloric acid kills bacteria and helps break down proteins, while pepsin and lipase begin the process of digesting proteins and fats, respectively.

3. Mechanical action: Mechanical action refers to the physical movement of food through the digestive tract. This includes chewing, which breaks down food into smaller pieces, and the churning and mixing actions of the stomach and intestines, which help mix food with digestive juices and further break it down.
