Discuss digestive System in detail.

The digestive system is a complex network of organs and processes responsible for breaking down food, absorbing nutrients, and eliminating waste. It plays a pivotal role in maintaining overall health and well-being. The process begins as food enters the mouth and continues through various stages involving different organs, each contributing to the efficient breakdown and absorption of nutrients.

Mouth and Esophagus: The digestive process starts in the mouth, where food is chewed and mixed with saliva. Saliva contains enzymes, like amylase, which begin the breakdown of carbohydrates. The tongue helps in manipulating food to form a bolus, which is then swallowed and moves down the esophagus via peristalsis—a series of wave-like muscle contractions. The esophagus has a lower esophageal sphincter that prevents the backflow of stomach contents.
