1. the action, process, or power of digesting: such as. a : the process of making food absorbable by mechanically and enzymatically breaking it down into simpler chemical compounds in the digestive tract.
2. Digestion in amoeba is intracellular taking place within the cell. The food taken in remains in a food vacuole or gastric vacuole formed by the cell membrane and small part of the cytoplasm. The vacuoles are transported deeper into the cells by cytoplasmic movements. Here they fuse with lysosomes that contain enzymes.
3. When you swallow, a flap called the epiglottis moves to block the entrance of food particles into your larynx and lungs. The muscles of the larynx pull upward to assist with this movement. They also tightly close during swallowing. That prevents food from entering your lungs.
4. Saliva is deeply associated with health or the functions of our body, including teeth and gums. The production of saliva is promoted when we chew food thoroughly. Saliva has various functions including chemical digestion and cleaning the mouth..
