Digestive System

Food is our fuel, and its nutrients give our bodies' cells the energy and substances they need to operate.Digestion is a very important process discussed in biology. We will learn about digestive system of human body and the process in this post.


Every living beings usually has tube-type digestive system in which food enters the mouth, passes through a long tube, and exits as feces (poop) through the anus which is just like a . The smooth muscle in the walls of the tube-shaped digestive organs rhythmically and efficiently moves the food through the system, where it is broken down into tiny absorbable atoms and molecules. Find below the diagram of digestive system, which explains the entire process.

 

During the process of absorption, nutrients that come from the food (including carbohydrates, proteins, fats, vitamins, and minerals) pass through channels in the intestinal wall and into the bloodstream. The blood works to distribute these nutrients to the rest of the body. The waste parts of food that the body can't use are passed out of the body as feces.

I hope this post has helped students looking out for diagram of digestive system and the process of digestion.
