Parts Of Human Digestive System

The digestive system of the human body is made up of a collection of organs that work together to transform food into energy for the body’s metabolic needs. 

The digestive system is composed of the gastrointestinal tract, as well as auxiliary organs such as the liver, pancreas, and gallbladder, according to anatomy. 

The gastrointestinal system (GI tract) consists of hollow organs that include the mouth, stomach, oesophagus, small intestine, and large intestine, which contains the rectum and anus, among other things.

The Human Digestive System and Nutrition are concerned with the intake of food by an organism and the subsequent utilisation of that food for energy. 

This is a critical mechanism that allows living beings to acquire their energy from a variety of sources, such as sunlight.

 The food that we consume goes through a great deal of processing before the nutrients contained within it can be used to generate energy. 

Digestion is the term used to describe this process. Humans and other animals have organs and systems that are specifically designed for this procedure.

Among the organs and systems involved in the digestive process are the alimentary canal and a number of auxiliary organs and organ systems.

The Digestive System has five primary functions, which are as follows:

The digestive system’s primary role is digestion and absorption of nutrients.

Important functions of the digestive system include the following:

Motility

Food flows through the digestive canal as a result of a process known as peristalsis, which is caused by the contraction of muscles in the gastrointestinal tract that transport food to the digestive system.

 Secretion

Secretion is defined as the release of enzymes, hormones, and other compounds by the body to aid in the digestion of food, hormones signal the body to produce digestive juices and notify the brain whether you are on an empty stomach or if you have eaten a substantial meal.

Digestion

The process of digestion breaks down proteins, lipids, carbohydrate, vitamin, mineral and water molecules into smaller molecules that can be absorbed through the digestive fluid and into the bloodstream during digestion. 

Absorption–

 Digested carbohydrates are transferred from the gut to the circulation, where they are distributed throughout the body by the circulatory or lymphatic systems for use or storage.

The healthy components of your meal are absorbed as it travels on its magnificent trip.

Excretion

This term refers to the process of eliminating indigestible substances and waste by-products from one’s body through defecation.

Parts Of Human Digestive System

Mouth

The digestive system diagram, which has been labelled, begins at the mouth. As a matter of fact, your body begins the digestion process even before you consume your first bite of food.

Oesophagus

The oesophagus is a tube that runs down the middle of the throat, near the windpipe or the trachea and it helps to digest food. The oesophagus is responsible for receiving the food that you swallow.

Stomach

This is the stage at which the food is combined with the enzymes in the stomach. 

A food enzyme is a substance that breaks down food into a form that can be consumed. 

A robust and strong acidic enzyme is secreted by cells in the stomach lining, and this enzyme is responsible for breaking down the food.

Small Intestine

There are three segments to the small intestine, which is a muscular tissue that measures 22 feet in length. 

The duodenum, jejunum, and ileum are the three sections of the digestive tract. 

Through the release of enzymes from the pancreas and the production of bile by the liver, food is broken down even further.

Pancreas

The pancreas secretes digestive enzymes into the duodenum, which is where they are used. This aids in the breakdown of fats, proteins, and carbs, among other things.

Liver

The liver is responsible for a variety of processes during the digestive process, the most important of which is the processing of nutrients that are absorbed by the small intestine.

Gallbladder

The gallbladder is the organ responsible for storing and concentrating the bile secreted by the liver and gallbladder.

 Large Intestine

The colon, also known as the large intestine, is in charge of processing waste in order to make it easier to empty your bowels. 

The colon is a muscular tube that is 6 feet in length that joins the small intestine with the rectum.

Rectum

The rectum is an 8-inch-long, straight tube that connects the colon to the anus. 

Anus

The anus is the final section of the digestive tube, and it measures 2 inches in circumference.

 The lining of the upper anus is responsible for detecting any content in the rectal cavity.

Conclusion

Digestion is the process by which big insoluble food molecules are broken down into smaller water-soluble food molecules, which can then be absorbed into the watery plasma of the bloodstream. 

When consumed by certain organisms, these tiny chemicals are absorbed into the bloodstream via the small intestine and circulatory system. 

Digestion is a type of catabolism that is commonly divided into two processes based on how food is broken down: 

• Mechanical digestion 
• Chemical digestion. 

We have a one-chambered stomach, as opposed to other animals such as cows, which have four chambers in their stomach.

Additionally, several components of the neurological and circulatory systems play an important role in the digestion process. 

The digestive system comprises a variety of organs and systems, including nerves, bacteria, hormones, blood, and other tissues and organs.
