Read this next. Jejunum Overview. Waves of muscle contractions called peristalsis pronounced: per-uh-STALL-sus force food down through the esophagus to the stomach. A person normally isn't aware of the movements of the esophagus, stomach, and intestine that take place as food passes through the digestive tract.

At the end of the esophagus, a muscular ring or valve called a sphincter pronounced: SFINK-ter allows food to enter the stomach and then squeezes shut to keep food or fluid from flowing back up into the esophagus. The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces.

An acidic environment is needed for the digestion that takes place in the stomach. By the time food is ready to leave the stomach, it has been processed into a thick liquid called chyme pronounced: kime. A walnut-sized muscular valve at the outlet of the stomach called the pylorus pronounced: pie-LOR-us keeps chyme in the stomach until it reaches the right consistency to pass into the small intestine.

Chyme is then squirted down into the small intestine, where digestion of food continues so the body can absorb the nutrients into the bloodstream.

The inner wall of the small intestine is covered with millions of microscopic, finger-like projections called villi pronounced: VIH-lie. The villi are the vehicles through which nutrients can be absorbed into the blood. The blood then brings these nutrients to the rest of the body. The liver under the ribcage in the right upper part of the abdomen , the gallbladder hidden just below the liver , and the pancreas beneath the stomach are not part of the alimentary canal, but these organs are essential to digestion.

The liver makes bile , which helps the body absorb fat. Bile is stored in the gallbladder until it is needed. The pancreas makes enzymes that help digest proteins, fats, and carbs. It also makes a substance that neutralizes stomach acid. These enzymes and bile travel through special pathways called ducts into the small intestine, where they help to break down food.

The liver also helps process nutrients in the bloodstream. These enzymes break down protein, fats, and carbohydrates. Bile has two main purposes: to help absorb fats and to carry waste from the liver that cannot go through the kidneys. Bile Ducts : Bile made in the liver travels to the small intestine through the bile ducts.

Gallbladder: A pear-shaped reservoir located just under the liver that receives and stores bile made in the liver. The gallbladder sends this stored bile into the small intestine to aid in the digestion of food. Colon Large Intestine : A 5- to 7-foot-long muscular tube that connects the small intestine to the rectum and is responsible for processing waste so that defecation is easy and convenient.

It is made up of the ascending right colon, the transverse across colon, the descending left colon and the sigmoid colon, which connects to the rectum. Rectum: An 8-inch chamber that connects the colon to the anus.

The rectum receives stool from the colon, sends signals to the brain if there is stool to be evacuated, and holds stool until evacuation can happen.
