Digestive System Diagram
We run, we work, we think, we talk. How do you think we do all of that? Yes as far as thinking and reasoning is concerned, our mind does play a big role. However, biologically our body is an amalgamation of different human body systems, each of which has a specific role to play. There are seven major organ systems that make up the human body. They are the nervous system, respiratory system, circulatory system, musculoskeletal system, digestive system, excretory system and the reproductive system. In this article we concentrate on the digestive system. To aid our understanding of the function and the various organs that constitute it, this article carries a labeled diagram of the digestive system and an unlabeled one at the end of the article for the readers to identify and mark different organs of the digestive system.
Digestive System Function
Our body is like a complex machine. It needs fuel to run. This fuel is provided by the food that we eat. The nutrients-carbohydrates and fats provide us this energy. However, just as a machine suffers from wear and tear, the cells of our bodies also wear out. New cells are required to replace the old and dead cells. The raw material for this growth is provided by proteins. We are also susceptible to a number of diseases which our immune system generally fights. Vitamins and minerals are the nutrients that strengthen our immunity. However, these nutrients need to be broken into simpler forms, that can be absorbed by our cells. This is where function of the digestive system begins. There are a number of glands like liver and pancreas (to name a few), that secrete enzymes into the various organs of the digestive system, that speed up the process of digestion. These enzyme, that are more specifically known as digestive enzymes, that aid in the reactions that break the complex nutrients in simpler forms, that can be transported by blood and absorbed by the cells. Read more about how does the digestive system work and benefits of digestive enzymes.
Digestive System Organs and Their Functions
This table gives a consolidated information about the different digestive system organs and their functions. Following diagram of the digestive system that is provided in the article, will give one a better understanding of this organ system, as the food moves down from the mouth, through the esophagus to the stomach, small intestine and the large intestine, before it is excreted through the rectum and the anus.
