 \huge\color{red} \mathfrak{Digestion \:  \:  in \:  \:  Humans </p><p>}

The process of digestion begins from the mouth and ends in the small intestine – the large intestines’ main function is to absorb the remaining water from the undigested food and enable bacterial fermentation of materials that can no longer be digested.

The alimentary canal or the gastrointestinal tract is a series of hollow organs and tubes that begins from the mouth cavity and continues into the pharynx, through the stomach, small intestines, large intestines, and finally ending at the anus.

Food particles gradually get digested as they travel through various compartments of the gastrointestinal tract.

The digestion process takes place in the following steps.

  \large\color{red} \mathcal{Ingestion:}

The very first step involves mastication (chewing). The salivary glands, along with the tongue, helps to moisten and lubricate food, before being pushed down into the food pipe.

 \large \color{red} \mathcal{Mixing \:  and \:  Movement:}

It involves the process of lubricating and manipulating food and pushing it down the food through the food pipe (using peristalsis), and into the stomach.

 \large \color{red} \mathcal{Secretion;</p><p>:}

The stomach, small intestine, liver, and pancreas secrete enzymes and acids to aid the process of digestion. It functions by breaking down food particles into simple components and easily absorbable components.

 \large \color{red} \mathcal{Digestion:}

The process of converting complex food particles into simpler substances in the presence of enzymes and acids secreted by different digestive organs.

 \large \color{red} \mathcal{Absorption:}

This process begins in the small intestine where most of the nutrients and minerals are absorbed. The excess water in the indigestible matter is absorbed by the large intestines.

 \large \color{red} \mathcal{Excretion:}

The process of removing indigestible substances and waste by-products from the body through the process of defecation.
