the minerals and vitamins that are useful to the body, should have been removed from the watery contents. These materials are then passed on to the large intestine. b. The waves of muscular contractions known as peristalsis move food down this thin-walled tube to a muscular bag known as the stomach. Both physical and chemical digestion occurs within the stomach. c. A structure at the bottom of the stomach known as the pyloric sphincter controls the entry of chyme into the first part of the small intestine and most of the chemical digestion occurs within the first meter. Once digested into smaller molecules, absorption can take place. d. Food is taken into the mouth where it is physically broken down by the teeth into smaller pieces. The presence of food in the mouth triggers a nervous reflex that causes the salivary glands to deliver a watery fluid called saliva to the mouth. e. Cells lining the stomach produce this highly acidic fluid, and the enzymes present commence the chemical breakdown of the protein component of the food. Eventually, the food is reduced to a creamy paste known as chyme. f. As undigested material accumulates in the rectum, it stimulates a response that leads to the evacuation of the waste through the anus. 1. The swallowing reflex allows food from the mouth to be moved into the esophagus.

раper.
a. On reaching the end of the small intestine, all the digested food products, along with
the minerals and vitamins that are useful to the body, should have been removed from
the watery contents. These materials are then passed on to the large intestine.
b. The waves of muscular contractions known as peristalsis move food down this
thin-walled tube to a muscular bag known as the stomach. Both physical and
chemical digestion occurs within the stomach.
c. A structure at the bottom of the stomach known as the pyloric sphincter controls the
entry of chyme into the first part of the small intestine and most of the chemical
digestion occurs within the first meter. Once digested into smaller molecules,
absorption can take place.
d. Food is taken into the mouth where it is physically broken down by the teeth into
smaller pieces. The presence of food in the mouth triggers a nervous reflex that
causes the salivary glands to deliver a watery fluid called saliva to the mouth.
e. Cells lining the stomach produce this highly acidic fluid, and the enzymes present
commence the chemical breakdown of the protein component of the food. Eventually,
the food is reduced to a creamy paste known as chyme.
f. As undigested material accumulates in the rectum, it stimulates a response that
leads to the evacuation of the waste through the anus.
1. The swallowing reflex allows food from the mouth to be moved into the esophagus.
