Write one function of each of the following
(1) salivary gland
(2) tongue
(3) Molar teeth
(4) saliva

Dear Student,
 

1) Salivary glands secrete the first of the digestive juices, the saliva. In the digestion process, the saliva helps the teeth and tongue to masticate and mix up the food thoroughly. Mucus in saliva helps in lubricating and adhering food particles into a bolus.  Then the bolus conveyed to pharynx for further digestion. Lysozyme present in saliva acts as an antibacterial agent that prevents infection. They also secrete salivary amylase enzyme that break down starch present in the food into simple sugars like maltose.

2) Tongue is a muscular structure present in the mouth. It serves many functions:
1. Taste: It functions as the primary organ of taste due to the presence of papillae and taste buds on it's upper surface. The taste buds present on the tongue helps the organism to recognise various taste sensations such as salty, sour, bitter and sweet. 
2. Swallowing: It is the part of the digestive system and helps in swallowing food. It mixes the food with saliva breaking the starch present in the food into simple sugars starting the process of digestion.
3. Speech: Tongue helps us to speak.

P.S. For the rest of the questions, kindly post them in a separate thread.

Regards
