The various steps of nutrition in human beings are as follows:
Ingestion:
  • In human beings, food is ingested through the mouth. The food is put into the mouth with the help of hands.
Digestion:
  • The digestion of food commences in the mouth itself.
  • The teeth cut the pabulum into small pieces, masticate and grind it. (Physical digestion)
  • The salivary glands in our mouth produce saliva (watery liquid) which contains an enzyme salivary amylase which digests the starch (carbohydrate) present in the food into sugar. (Chemical digestion)
  • Our tongue helps in mixing this saliva with food.
  • The digestion of food remains incomplete in the mouth.
Oesophagus:
  • The slightly digested food in the mouth is swallowed by the tongue and goes down the food pipe called oesophagus.
  • When the marginally digested food enters the victuals pipe, the walls of victuals pipe start contraction and expansion forms of kineticism called as a peristaltic movement.
  • This peristaltic movement of food pipe pushes the slightly digested into the stomach.
Stomach:
  • The stomach is a J-shaped organ present on the left side of the abdomen.
  • The stomach walls contain s three tubular glands in it walls which secrete gastric juice.
  • The gastric juice contains three substances: Hydrochloric acid, the enzyme pepsin, and mucus.
  • The hydrochloric creates an acidic medium which facilitates the action of the enzyme pepsin i.e. digestion of protein.
  • The mucus helps to protect the stomach wall from its own secretions of hydrochloric acid.
  • The partially digested food then goes from the stomach into the small intestine.

Lessons-Worksheets-Question Papers-CBSE Class 2 English CBSE 2nd Class English – One and Many  In this blog, we share the spelling rules used in the concept of  One  and Many. When there is only one of a naming word (noun), it is said to be a  singular noun . When a noun shows more than one, it is said to be in the  plural . We can add  –S, -es, -ves or ies  to show that there is more than one noun.  For example,  we say many birds, four biscuits, six brushes. But for the students of  Class 2 , it’s very difficult and confusing to understand where to use  s , es, ves or ies  in the form of many.
