Class 11 zoology Digestion and absorption

 In order for our bodies to absorb nutrients from the food we eat, digestion and absorption are essential functions. Food is first broken down into smaller molecules in the mouth by enzymes, which initiate digestion. Further breakdown of food takes place in the stomach and small intestine due to the many enzymes and acids it comes into contact with on its journey through the digestive tract. Nutrients are taken into the circulation in the small intestine, where they are subsequently utilized by cells across the body. Our bodies get the vital nutrients they require for growth, healing, and energy thanks to this complex process.

Digestion breaks down food into smaller molecules, while absorption is the process of taking these molecules into the bloodstream. This happens mainly in the small intestine, where enzymes break down food, and nutrients are absorbed through its lining. The body then uses these nutrients for energy, growth, and repair. Any leftover waste is eliminated through the large intestine.
