Answer:-
In reaction to the smell, sight, or thought of food, the first hormonal response is that of salivation ( starts making saliva ) The salivary glands secrete more saliva in response to the stimulus presented by food in preparation for digestion. Simultaneously, the stomach begins to produce hydrocholoric acid to digest the food
The salivary glands are glands inside a person's mouth and throat that produce the watery and mucous-containing fluid known as saliva. Saliva is constantly released into our mouth to keep it lubricated and to help us chew and swallow food. There are three pairs of salivary glands: sublingual, parotid and submaxillary
and for the end the main digestive enzymes in your body are : -
1- Amylase, produced in the mouth. It helps break down large starch molecules into smaller sugar molecules.
2- Pepsin, produced in the stomach. Pepsin helps break down proteins into amino acids.
3- Trypsin, produced in the pancreas. Trypsin also breaks down proteins
4- Pancreatic lipase, produced in the pancreas. It is used to break apart fats.
5- Deoxyribonuclease and ribonuclease, produced in the pancreas. They are enzymes that break bonds in nucleic acids like DNA and RNA
Answer:
The <u><em>pharynx</em></u> starts an involuntary swallowing action when senses food.The <u><em>esophagus</em></u> squeezes food down the digestive tract by an involuntary synchronized muscle movement called the <u><em>peristalsis</em></u>. Food that has been digested in the <u><em>stomach</em></u> is processed into a thick liquid called <u><em>chyme</em></u>.
Explanation:
Digestion can be described as a process in which food is broken down so that an organism can use the energy in the food. The process of digestion is voluntary in the start as we take in food. But after this, the process of digestion becomes involuntary from the pharynx. The esophagus is the large tract through which food is squeezed into the stomach from the mouth. The squeezing is done by the force generated by muscle movements which is termed as peristalsis.
