• Chapter 3 Digestion

2
Carbohydrates

• Digestion of carbohydrate begins in the mouth,
  with the secretion of the enzyme salivary amylase
  from the serous cells of the salivary gland.
  This enzyme breaks starch and glycogen into
  disaccharides.

3
Carbohydrates

• The salivary glands are grouped into three
  categories the parotid gland, submandibular
  glands, and sublingual, all located near the
  mouth.
• As the food is swallowed, it moves into the
  esophagus (a straight collapsible tube), which
  essentially provides a passageway from the
  pharynx to the stomach.

4
Carbohydrates

• The Peristalsis is responsible
• for pushing the food into
• the next organ.

5
Cardiac Sphincter

• The bolus passes through the cardiac sphincter,
  into the first section of the stomach.

6
Regions of the Stomach

• The stomach is divided into several regions the
  cardiac region, body region, fundic region, and
  pyloric region.

7
Stomach

• The stomach works to mix and churn the food,
  which aids in further digestion of carbohydrates.
  At this point, the bolus is converted into a
  semifluid paste of bolus and gastric juices
  called chyme.

8
Chyme through Pyloric Sphincter

• The chyme then travels through the pyloric
  sphincter into the first section of the small
  intestines.
