ya what is the answer
C. Digestion, absorption, elimination
The three main processes that food undergoes in the digestive system are:
1. Mechanical digestion: This process involves the physical breakdown of food into smaller pieces. It starts in the mouth with chewing and continues in the stomach through the churning and mixing of food with digestive enzymes and stomach acid.
2. Chemical digestion: This process involves the breakdown of complex molecules within food into simpler substances that can be absorbed by the body. It begins in the mouth with the action of salivary enzymes on carbohydrates, and continues in the stomach and small intestine with the release of digestive enzymes to break down proteins, carbohydrates, and fats.
3. Absorption: After food is broken down, the nutrients are absorbed into the bloodstream through the walls of the small intestine. Nutrients such as sugars, amino acids, fatty acids, vitamins, and minerals are transported to various cells and organs in the body to be used for energy, growth, and repair.
To understand these processes more thoroughly, one can study the anatomy and physiology of the digestive system. Reading textbooks or scientific articles on topics such as the structure and function of the digestive organs, the role of enzymes, and the mechanisms of nutrient absorption would be helpful. Additionally, observing diagrams, animations, or videos that explain the digestive process can provide a visual representation of how food is digested.
