How the Digestive System Works

The digestive system is an important part of the body as it allows the tissues and organize to receive essential nutrients for proper function. This works by the digestive system breaking down food, extracting those nutrients, and then converting them into energy. This is an involuntary process that begins as soon as food is consumed.

The digestive system consists of several parts: the esophagus, stomach, liver, gallbladder, pancreas, small intestine, large intestine, rectum, and anus; all of these parts play different roles when it comes to digestion.

The esophagus consists of a hollow tubular-shaped organ between the neck and chest, connecting the mouth top the stomach. The muscles within the esophagus are what propel food into your stomach. The stomach is a large organ that digests food through different acids and enzymes, holding it for anywhere from 2 to 8 hours. The liver is an organ that filters toxins from the blood, as well as produces bile; breaking down things like fats, proteins, and carbohydrates. The sac-shaped organ known as the gallbladder stores bile that is produced by the liver, then releases it when necessary. The pancreas produces insulin as well as promotes metabolism. The small intestine begins the breakdown of food and absorbs nutrients, while the large intestine turns the food you eat into feces. Connected to the end of the large intestine is the rectum, which temporarily stores feces, which are then excreted through the anus.
