Trimester 1 Unit 2

Question 1

an enzyme that breaks down fat

Answer 1

Lipase

Question 2

where food is broken down for the small intestine. Both chemical and physical breakdown happens due to the enzymes and the muscle contractions.

Answer 2

Stomach

Question 3

Enzyme in saliva that breaks chemical bonds

Answer 3

Amylase

Question 4

the process of wave-like muscle contractions of the alimentary tract that moves food along

Answer 4

Peristalsis

Question 5

An enzyme that breaks down proteins into smaller polypeptide fragments

Answer 5

Pepsin

Question 6

a mixture of enzymes and partially-digested food that moves to the small intestine

Answer 6

Chyme

Question 7

Fluid loaded with lipids and salts

Answer 7

Bile

Question 8

an enzyme that breaks down fat

Answer 8

Lipase

Question 9

where digestion begins as chewing and saliva start breaking down the food. Both mechanical and physical.

Answer 9

Mouth

Question 10

A muscular tube that connects the mouth to the stomach transports food. No breakdown occurs here.

Answer 10

Esophagus

Question 11

A muscular and elastic sac serves mainly to store food, break it up mechanically, and begin the chemical digestion of proteins and fat.

Answer 11

Stomach

Question 12

The digestive organ where most chemical digestion and absorption of food takes place. The chyme enters it and mixes with all enzymes and digestive fluids from the pancreas, liver, and duodenum.

Answer 12

Small Intestine

Question 13

The last section of the digestive system is where water is absorbed from food and the remaining material is eliminated from the body. Physical breakdown because there are no chemical reactions.

Answer 13

Large Intestine

Question 14

produced hormones that regulate blood sugar, produce enzymes that break down carbohydrates, proteins, lipids, and nucleic acids, and produce sodium bicarbonate.

Answer 14

Pancreas

Question 15

Produces bile

Answer 15

Liver

Question 16

A muscular sac attached to the liver that secretes bile and stores it until needed for digestion

Answer 16

Gallbladder

Question 17

Separating the thoracic cavity from the abdominal cavity

Answer 17

Diaphragm

Question 18

supports, anchors, and separates the liver into the right and left lobe

Answer 18

Falciform Ligament

Question 19

a tube that carries bile from the liver and gallbladder to the small intestine

Answer 19

Common Bile Duct

Question 20

connects the gallbladder to the common bile duct

Answer 20

Cystic Duct

Question 21

neutralize the chyme-sodium bicarbonate from pancreas, emulsify fats with bile from liver/gallbladder

Answer 21

Duodenum

Question 22

completes chemical digestion and absorption of nutrient molecules into the bloodstream

Answer 22

Jenjunum

Question 23

2-3 feet long & finishes absorbing nutrient molecules. Has special ‘traps’ called Peyer’s patches that help regulate the bacterial population

Answer 23

Ileum

Question 24

carry enzymes and sodium bicarbonate

Answer 24

Pancriatic duct

Question 25

very muscular section of the large intestine

Answer 25

Haustrum

Question 26

may serve as a reservoir for beneficial gut bacteria

Answer 26

Veriform Appendix

Question 27

Physical breakdown of large pieces of food into smaller pieces

Answer 27

Mechanical Digestion

Question 28

Enzymes break down food into smaller molecules

Answer 28

Chemical Digestion

Question 29

Fingerlike extensions of the intestinal mucosa that increase the surface area for absorption

Answer 29

Villi

Question 30

the number of protons in the nucleus of an atom

Answer 30

Atomic Number

Question 31

the sum of the number of neutrons and protons in an atomic nucleus

Answer 31

Mass Number

Question 32

how much of a drug there is

Answer 32

Concentration

Question 33

the outer surface of an object

Answer 33

Surface Area

Question 34

mass of 1 and +1 charge

Answer 34

Proton

Question 35

mass of 1 and 0 charge

Answer 35

Neutron

Question 36

Mass of almost 0 and charge of -1, found in the nucleus

Answer 36

Electron

Question 37

Breaks down food into smaller molecules. Absorbs these nutrients into the body.

Answer 37

digestive system
