FAQs (Frequently Asked Questions)

There are four layers on the walls of the alimentary canal. These include:

  • Serosa – It is the outermost layer of the alimentary canal.
  • Muscularis – It helps in moving and chumming the food by the enzymes of digestion.
  • Sub-Mucosa – It supports the mucosa. It consists of big blood vessels and nerves with uneven layers of connective tissues. 
  • Mucosa – It is the innermost layer of the alimentary canal. It is helpful for absorption and secretion. 

Among all the other organs, the liver is the heaviest and the largest. It does not directly get involved in the digestion of the food particles but its main function is the secretion of bile juice which helps in the emulsification of fats. The major function of bile juice is to break down the large lip globules into small lipid globules. 

Teeth are embedded in deep sockets of the jaw bone. This attachment of teeth to the jaw is known as Codont.

Mammals and human beings produce two sets of teeth in their lifetime. First, as a set of milk teeth or deciduous teeth which are temporary while they are children and second, a set of teeth (that are permanent) as they become adults. In other words, it can be said that the temporary milk teeth are replaced by permanent adult teeth. This dentition is known as Diphyodont.

The digestion of protein begins in the stomach and ends in the small intestine. Digestive juice called gastric juice is secreted by gastric glands which are found on the walls of the stomach. The gastric juice contains hydrochloric acid, mucus, renin, and pepsinogen. Pepsinogen on contact with the acidic medium created by hydrochloric acid gets converted into pepsin (digestive protein enzymes). The activated pepsin, then, converts the proteins into peptides and proteases.
