Answer 1

ᴩʀᴏᴄᴇꜱꜱ ᴏꜰ ᴅɪɢᴇꜱᴛɪᴏɴ ɪɴ ꜱᴛᴏᴍᴀᴄʜ :

→ After the food is swallowed, it slides down the Pharynx into the

o e s o p h a g u s (food pipe). The oesoohagus leads from your mouth to the stomach. It is made up if muscles.

These muscles gently move push food down to your stomach in a wave like action called

p e r i s t a l s i s.

This movement takes place throughout the Alimentary Canal to push the food forward.

Your stomach is a J-Shaped Bag made up of muscles. It can hold up to two litres of food at a time.

Food stays in the stomach for few minutes to a few hours depending on the type of food eaten.

The inner lining of the stomach secretes mucous,hydrochloric acid and digestive juices.

The m u c o u s protects the inner lining of the stomach. The acid kills bacteria that enter along with food and also helps in digestion of proteins. The stomach muscles squeeze and mix the food with d i g e s t i v e j u i c e s .

The Digestive juices break down protiens into simpler substances.

Thus, the food gets partly digested in the stomach.

Then it goes into i n t e s t i n e where most of the digestion occurs.

Process of digestion in stomach :

➠ In the stomach, food gets mixed with gastric juice and enzyme-like pepsinogen, prorenin, lipases, and mucus.

➠ Gastric juice helps to maintain the pH of the stomach and it also converts pepsinogen and prorenin into pepsin and renin which help to break down protein into proteases, peptones, and large peptides.
