Digestion is an important body process where the food we eat, gets converted into substances which can be absorbed by the body. Many different organs together form the digestive system, these organs work together to digest the food. You can refer to the below digestive system diagram, for better understanding.

The digestive process begins in the mouth. Food is partly broken down by the process of chewing and by the chemical action of salivary enzymes (these enzymes are produced by the salivary glands and break down starches into smaller molecules).

After being chewed and swallowed, the food enters the esophagus. The esophagus is a long tube that runs from the mouth to the stomach. It uses rhythmic, wave-like muscle movements (called peristalsis) to force food from the throat into the stomach. This muscle movement gives us the ability to eat or drink even when we're upside-down..

The stomach is a large, sack-like organ that churns the food and bathes it in a very strong acid (gastric acid). Food in the stomach that is partly digested and mixed with stomach acids is called chyme.

The liver's main job is to filter the blood coming from the digestive tract, before passing it to the rest of the body. The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions.

The pancreas is an organ that makes hormones and enzymes to help digestion. The pancreas helps break down carbohydrates, fats and proteins. The pancreas is behind the stomach and is on the left side of the human body.

Is a small organ that aids mainly in fat digestion and concentrates bile produced by the liver.

Is the first section of the small intestine, precedes the jejunum and ileum and is the shortest part of the small intestine, where most chemical digestion takes place.

Is the longest and most movable part of the colon, The transverse colon as well as the ascending colon are responsible for absorbing water and salts.

Is the part of the colon located between the cecum and the transverse colon. The ascending colon as well as the transverse colon are responsible for absorbing water and salts.

The descending colon is the part of the colon from the splenic flexure to the beginning of the sigmoid colon and thereby part of the large intestine. The function of the descending colon in the digestive system is to store food that will be emptied into the rectum.

Is the final section of the small intestine. The function of the ileum is mainly to absorb vitamin B12 and bile salts and whatever products of digestion that were not absorbed by the jejunum.

Is a pouch, usually peritoneal, that is considered to be the beginning of the large intestine. It receives fecal material from the ileum, and connects to the ascending colon of the large intestine.

The jejunum is the second portion of the small intestine, and it has a lining which is specialized in the absorption of monosaccharides (fully digested carbohydrates) and amino acids (fully digested proteins).

The appendix sits at the junction of the small intestine and large intestine. It’s a thin tube about four inches long. Normally, the appendix sits in the lower right abdomen. The function of the appendix is unknown. One theory is that the appendix acts as a storehouse for good bacteria, “rebooting” the digestive system after diarrheal illnesses. Other experts believe the appendix is just a useless remnant from our evolutionary past. Surgical removal of the appendix causes no observable health problems.

Is the part of the large intestine that is closest to the rectum and anus. The food travels across the abdomen in the transverse colon, goes back down the other side of the body in the descending colon, and then through the sigmoid colon.

Is the external opening of the rectum, its closure is controlled by sphincter muscles. Feces are expelled from the body through the anus during the act of defecation, the primary function of the anus

The lower part of the large intestine, where feces are stored before they are excreted.
