Absorption biology

The digestive tract consists of the gastrointestinal tract, also called the digestive tract, and the liver, pancreas and gallbladder. The gastrointestinal tract is a series of hollow organs joined together in a long, twisted tube that runs from the mouth to the anus. The hollow organs that make up the gastrointestinal tract are the mouth, esophagus, stomach, small intestine, large intestine and anus. The liver, pancreas and gallbladder are the solid organs of the digestive tract.

The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.

Bacteria in the gastrointestinal tract, also called intestinal flora or microbiota, help with digestion. Parts of the nervous and circulatory systems also help. Working together, the nerves, hormones, bacteria, blood, and organs of the digestive tract digest the food and liquids a person eats or drinks each day.

What is the absorption of nutrients

The digestive system is a set of organs whose primary mission is to promote the orderly progression of food, digestion and absorption. For this, a series of phenomena must occur along the different parts that constitute it.

The digestive tract is constituted by the mouth, the pharynx, the esophagus, the stomach, the small intestine and the large intestine or colon. In each of these parts of the digestive tract take place the different events that will allow the absorption of the different foods ingested.

The tongue and teeth are housed in it, the salivary glands pour their contents, and the chewing and salivation of food takes place, forming the food bolus that facilitates its swallowing.

A tube approximately 30-35 centimeters long, which collects the food bolus after the buccopharyngeal phase of swallowing. Thanks to a series of peristaltic movements, the alimentary bolus progresses towards the stomach, therefore, the esophagus only participates in the orderly progression of the food.

The large intestine eliminates them

Large intestine: Waste products of the digestive process include undigested parts of food, liquids and older cells from the lining of your gastrointestinal tract. The large intestine absorbs water and transforms liquid waste into stool. Peristalsis helps move the stool into the rectum.
