ANSWERS EXPERT VERIFIED GRADED A+
◉ esophagus Answer: the tube that connects the throat with the
stomach
◉ esophagus role: Answer: to transport food to the stomach (food
will then land on the epiglottis)
◉ epigolottis Answer: folds down over the trachea, or wind pipe,
during swallowing to prevent food from entering the trachea.
Without this, food would accidentally enter the trachea, resulting in
choking.
◉ sphincter muscle Answer: a circular muscle located at the end of
the esophagus. Once food passes through it on the way to the
stomach, the muscle constricts (closes) and prevents the backflow of
the stomach contents into the esophagus.
◉ stomach Answer: has a 4 cup capacity and can hold food for 2 to 3
hours, or longer, until it is ready to pass into the small intestine
,◉ stomach's role: Answer: to store, mix, dissolve, and continue the
digestion of food
◉ gastric juice: Answer: A digestive fluid secreted by the stomach
and mixed with enzymes. Prepares protein for digestion and
activates the enzymes.
◉ Pepsin Answer: an enzyme that breaks down proteins
◉ Gastric Lipase Answer: an enzyme that begins fat difestion
◉ Chyme Answer: the resulting substance when food particles are
mixed with stomach acids and enzymes. It is a very watery mixture
that slowly empties from the stomach into the small intestine
(occurs over a period of one to four hours).
◉ Gastrin Answer: the hormone responsible for controlling the
concentration of acid in the stomach. It is produced when we begin

, ◉ Intrinsic factor Answer: a vital glycoprotein produced in the

◉ In order for vitamin B-12 to be absorbed, _________________________
must be present. Answer: intrinsic factor
◉ pyloric sphincter Answer: controls the release of chyme into the
small intestine
◉ Small intestine Answer: approximately 20 feet long and connects
the stomach to the large intestine (named for its small diameter).
Vast majority of all digestion and absorption of nutrients occurs
here.
◉ 3 main sections of the small inestines: Answer: duodenum,
jejunum, and ileum
◉ Duodenum: Answer: the first portion of the small intestine is
wider than the remainder of the small intestine
◉ Jejunum: Answer: the middles section of the small intestines
◉ Ileum: Answer: the final section that connects the small and large
