Digestive System Diagram
Here is the digestive system diagram of the human digestive system.
The Digestive System Anatomy
The digestive system diagram illustrates the digestive tract from the mouth through to the anus, together with all of its associated organs and glands. It is the means by which ingested food is broken down in the alimentary canal into a form that can be absorbed and assimilated by the tissues of the body.
Stomach & Gal-bladder
The passage of food from the stomach to the pyloric (Valve is known as Peristalsis)
Small Intestine (Duodenum, Ileum, Jejunum)
Large Intestine (Cecum, Colon, Rectum)
Excreted from the Body (anus)
Let's follow the digestive system tract:
The ultimate purpose of digestion is to break large pieces of food down into molecules small enough to pass carefully into the bloodstream and then into individual cells throughout the body. Only vitamins, minerals and water are used by the body in their raw state without alteration.
Digestive System Diagram in Details:
It starts at the .
When we eat, we chew our food which is crushed up by our teeth and mixed with saliva so it becomes mushy.
We swallow the mush and it travels through the esophagus (a long tube that runs from the mouth, before it goes into the stomach). Inside the stomach there are juices that mix the food until it thickens in a soup-like consistency.
The esophagus opens into the stomach , which is a large chamber consisting of the fundus (the fundus and body of the stomach, which are usually referred to together and constitute the majority of the stomach in size, are where the stomach stores food before it is delivered to the intestine). The entire involvement of the stomach in digestion is called the gastric phase of digestion.
Then, the food goes into the small intestine : which is a narrow long-winded tube where most of the digestion takes place. It extends 6.7–7.6 meters (22-25 ft) from the stomach to the large intestine.(Though the small intestine is longer than the large intestine, it has a smaller diameter. That is why it is called the "small intestine".)
Juices from the liver mush up the food even more, and good things from the food go into the blood, which takes them to parts of the body where they are needed.
The food then goes to the large intestine . Water from the food goes into the blood.
By now, the body has taken all the things it needs from the food. What is left is waste that is not needed by the body. It gets stored at the end of the large intestine inside the rectum. The waste must leave or the body will get sick. Muscles push the waste out of the body through the , which is the opening in your bottom.
How Long Does It Take Food To Digest?
VERY IMPORTANT NOTE: By now, the body has taken all the things it needs from the food. What is left is waste that is not needed by the body. It gets stored at the end of the large intestine inside the rectum. The waste must leave or the body will get sick.
As for the digestion time, it is basically a process of breaking down big food particles into individual molecules, tiny enough to squeeze through the intestinal lining into the bloodstream.
The digestion process takes between 24 and 72 hours, six to eight hours to pass through your stomach and small intestine. Then the food enters your large intestine (colon) for further digestion and absorption of water. Elimination of undigested food residue usually begins after 24 hours. Complete elimination from the body may take several days."
