The mouth is the first part of the digestive system through which food enters the body and the process of digestion begins. The teeth and tongue helps to break down the food into smaller pieces, making it easier for the digestive enzymes to work. The Saliva produced in the mouth contains an enzyme called amylase, which helps to break down starch into simple sugars. The tongue also helps to mix the food with the saliva, which is essential for digestion.

Guard cells surround the stomata on the underside of leaves and regulate the gas exchange necessary for photosynthesis. They change shape to open and close the tiny pores. The stomata close when it is dark or the water level is low, while they open when there is plenty of light and water. Two theories, the potassium ion concentration theory and the sugar concentration theory, explain how the guard cells regulate the opening and closing of the stomata pores.

Emulsification of fats is a significant process in our body, in which large fat globules are broken down into small, evenly distributed fat particles by the action of the bile salts present in bile juice. This process increases the efficiency of fat-digesting enzymes, aids in the digestion and absorption of fats, and provides a larger surface area for enzymes to act upon. Overall, the significance of emulsification is crucial for proper fat digestion and absorption in the body.

Herbivores and omnivores have longer digestive tracts than carnivores. Herbivores consume fibre-rich plants with cellulose, requiring extended digestion time. A longer small intestine allows herbivores to fully break down cellulose, aided by bacteria. Carnivores lack cellulase enzymes, resulting in a shorter small intestine. The difference in tract length arises from dietary needs and cellulose digestion capabilities.
