Human Alimentary canal has the following parts
Buccal Cavity:
The tongue, teeth, and salivary gland are all found in the mouth, which is also known as the mouth. It is the point at which food enters the digestive system. Mastication breaks down food into simpler molecules in the buccal cavity, and salivary amylase breaks down starch into simpler carbs.
Oesophagus:
The buccal cavity is connected to the Oesophagus, a long tube-like structure. The oesophagus connects the buccal cavity to the stomach and aids in the ingestion of food. A valve in the oesophagus prevents food particles from backflowing.
Stomach:
The stomach is a J-shaped structure that contains gastric glands. The hydrochloric acid, pepsin, and mucus secreted by the gastric glands aid in the digestion of food.
Small Intestine:
The small intestine is a lengthy, coiled structure. The small intestine is responsible for the majority of food absorption. Specialized features in the small intestine aid in the absorption of digested food. The folds in the small intestine improve the absorption area. The small intestine also features microvilli, which are fingerlike projections that are well fed by blood vessels.
Large Intestine :
Its lumen is greater than that of the small intestine and it is shorter than that of the small intestine. The large intestine’s primary role is to absorb water from the remaining indigestible food stuff and to remove waste from the body.
Rectum:
The rectum is formed by the opening of the large intestine. The rectum is where waste and undigested food are kept.
Anus:
It’s the terminus of the alimentary canal’s opening. Anus is the exit point for solid waste items from the body.
