Key Topics to Revise

1

Our Sense of Taste

  • Our tongue helps us taste food. It can detect different kinds of tastes.
  • The main tastes we can identify are: sweet, sour, salty, bitter, and spicy.
  • Different parts of the tongue are more sensitive to different tastes — the tip usually feels sweet, the sides feel sour and salty, and the back feels bitter.
2

Role of Smell in Tasting

  • Our nose and tongue work together to help us identify food.
  • Smell helps us recognise food even before we put it in our mouth — for example, Hency recognised fried fish by its smell.
  • When your nose is blocked (during a cold), food seems tasteless even if nothing is wrong with your tongue.
3

Chewing and the Start of Digestion

  • Digestion begins in the mouth — this is a very important fact.
  • When we chew food, our teeth break it into smaller pieces, making it easier to digest.
  • Saliva mixes with the food while we chew. Saliva has special juices that start breaking down the food.
4

Journey of Food – From Mouth to Stomach

  • After we chew and swallow food, it travels through our body.
  • The path of food: Mouth → Food pipe (Oesophagus) → Stomach → Small intestine → Large intestine → Waste out of the body.
  • The stomach churns the food and mixes it with digestive juices to break it down further.
