Explon Human digestive system with the help diagram
Answers
Answer:
The process of breaking down large food particles into smaller and water-soluble particles, which can be easily absorbed by the blood plasma is termed digestion. All parts of the body are involved in the uptake and digestion of food along with the elimination of undigested material.
digestion is a vital process.
What is the Alimentary Canal?
The alimentary canal is mainly referred to as the pathway by which food enters our body and moves out through the anus after digestion. It is a tube-like structure that starts from the mouth and ends in the anus. The alimentary canal plays a primary role in human digestion and is also termed the digestive tract.
Organs of the Alimentary Canal
The main organs of the alimentary canal are:
The Mouth and Oral cavity
Oesophagus
Stomach
Small intestine
Large intestine
The digestive system plays a significant role in the digestion process, which is composed of the alimentary canal and other associated glands. The alimentary canal is divided into five main parts- mouth, esophagus, stomach, small intestine, small intestine, and lastly large intestine.
Explanation:
Mouth — It includes teeth, salivary glands, and tongue. It is the beginning of the digestive tract and the process of digestion begins from the mouth, where teeth help by breaking and grinding the food molecules followed by the saliva mixing with the food particles.
Pharynx –It is a fibromuscular, Y-shaped tube-like structure, attached to the terminal end of the mouth. It is involved in the passage of chewed food from the mouth through the esophagus.
Oesophagus —This is a muscular tube, measuring 25 cm long and located near the trachea connecting to the pharynx. It is the upper part of the gastrointestinal tract and mainly delivers the food particles from the mouth to the stomach.
Stomach –It is a hollow and muscular organ, situated towards the left side of the abdominal cavity and beneath the diaphragm. It is a vital organ, which functions by storing the food, providing enough time to digest meals, produces hydrochloric acid and digestive enzymes that maintain the process of digestion.
The Small Intestine is a thin and long tube-like structure measuring about 9 to 10 feet long and part of the lower gastrointestinal tract. The small intestine is located just behind the stomach, which is found completely coiled and consists of folds and ridges.
The Large Intestine is a thick and long tube-like structure measuring about 4 to 5 feet long. It is present just beneath the stomach and wraps over the superior and lateral edges of the small intestine. It functions by absorbing water and support in the breakdown of wastes to fetch small nutrients.
Liver –The liver is a large, reddish-brown, triangular-shaped organ of the digestive system, which is located to the right of the stomach. It functions by processing the absorbed food from the small intestine, produces bile, which helps in the digestion of fat in the small intestine.
