List the role of each of the following in our digestive system:
- Hydrochloric acid
- Trypsin
- Muscular walls of stomach
- Salivary amylase
उत्तर
- Hydrochloric acid: Food is softened and potentially food-borne bacteria that may have entered the stomach are killed. By giving them an acidic pH, it activates the stomach's protein-digesting enzymes.
- Trypsin: It aids in triggering all other small intestine enzymes that aid in the digestion of different food components. It also aids in the digestion of proteins.
- Muscular walls of stomach: They use their squeezing to aid in churning the food as it travels through the alimentary canal.
