Role of Enzymes in Digestion

The human digestive system is an intricate series of organs that work together to break down food into nutrients which can be absorbed into the bloodstream. The process begins in the mouth, where mechanical and chemical digestion occurs, and continues through the stomach and intestines. Each organ plays a unique role in ensuring the effective digestion and absorption of nutrients. For instance, the stomach secretes acids and enzymes that aid in this process.

It is essential to understand how specific enzymes facilitate digestion at different stages. For example, amylase initiates the breakdown of carbohydrates, while pepsin begins protein digestion. Understanding these roles can help in grasping how nutrients are extracted and utilized by the body.
