5. Drill Question Answers
(1) Mouth, Esophagus, Stomach, Small Intestine, Large
Intestine
(2) Chewing
(3) The enzyme amylase in your saliva breaks down larger
carbohydrates into smaller ones.
(4) The mushy mass of food that exits your mouth.
(5) Buccal Phase  Pharyngeal-Esophageal Phase
(6) You voluntarily use your tongue to push food to the back of
your throat.
(7) The esophagus involuntary squeezes the food down to your
stomach.
(8) Nothing, it just squeezes down.
(9) The wave-like contractions of your digestive muscle.
(10) Churning, this is initiated by the release of serotonin.
(11) Through gastric juice.
(12) Hydrochloric Acid, Pepsin and Rennin enzymes.
(13) The hormone gastrin is released from the g-cells within the
rugae of the stomach.
(14) The pH of your stomach drops.
(15) The liquidy-smoothie-substance that leaves the stomach.
(16) Duodenum  Jejunum  Ileum
(17) All remaining biomolecules from your food are broken
down.
(18) To emulsify (separate) lipid molecules.
(19) It contains enzymes used to metabolize all the remaining
biomolecules.
(20) Protein
(21) Protein
(22) Lipid

6. (23) Carbohydrates
(24) The sphincter of oddi
(25) When CCK or cholecystokinin is released into the
duodenum.
(26) To neutralize the acidic contents of the food.
(27) Useful nutrients are absorbed through microvilli directly
into your blood stream.
(28) Mucus to lubricate the food-mass, and lysozyme to help kill
some bacteria.
(29) Cecum  Ascending Colon  Transverse Colon 
Descending Colon
(30) Water is absorbed, and bacteria break down compounds
producing vitamins.
(31) Finger like structure that hangs off of your cecum.
It can sometimes collect waste, leading to appendicitis and
the removal of the organ.

then it drops onto your anus/the voluntary sphincter.

stomach and back out your mouth.
(34) The release of acid from your stomach back up your
esophagus, usually due to a loose esophageal sphincter.
(35) The forcing of harmful/toxic food substances out of your
colon, not allowing water to be absorbed, resulting in the
water-waste.

covering the tube. Air is pumped up against the food mass
to try and eject it out.

7. (38) An open would or ulcer inside the mouth, resulting from an
over-population of bacteria, and over-secretion of acid on
the oral tissue.
(39) An open would in the stomach, resulting from an overpopulation of bacteria, and over-secretion of acid on the
stomach tissue.

(54) Useful nutrients and needed amounts of water are put back
into the blood.
(55) Acidic/Basic compounds, drugs/toxins are forced out into
