Digestion System -Unit 1

Front 1

Ingestion

Back 1

eating the food

Front 2

Digestion

Back 2

is chemical reactions breaking down foods into smaller particles.

Front 3

Absorption

Back 3

nutrients that pass through the cells to go into the blood vessels.

Front 4

Assimilation

Back 4

absorbed nutrients created into new cell parts.

Front 5

Transport

Back 5

nutrient that enter the blood are transported around the body.

Front 6

Why is it important to digest large food molecules?

Back 6

it easier to be absorbed, and in order to pass through the cells ( plasma membrane) it has to be small.

Front 7

Why are enzymes required?

Back 7

speeds up the process of hydrolysis by lowering the activation energy. (saves time and energy).

Front 8

Peristalsis

Back 8

wave-like muscle contractions.
pushes food from Esophagus down to the stomach.

Front 9

Gastric Juice

Back 9

made of hydrochloric acid and pepsin.
converts food meal into acid chyme. (chemical reactions)

Front 10

Mucus

Back 10

is coated on the lining of the stomach.
helps prevent the gastric acid from destroying the cells.

Front 11

Epiglottis

Back 11

prevents mixing food with air. Prevents choking.

Front 12

Duodenum

Back 12

the first part of the small intestine--> mixes acid chymes with acid from pancreas, liver, and gallbladder.

Front 13

Sodium Bicarbonate

Back 13

produced by the Pancreas, and helps neutralize he stomach acids.

Front 14

Proteases

Back 14

digest protein

Front 15

Bile

Back 15

produced by the liver, and stored in the gallbladder. It turns fat into fatty acids.

Front 16

Microvilli or Villi

Back 16

the small has a huge surface area because of Microvilli and Villi that increases the rate of absorption.

Front 17

Lacteal

Back 17

the core of each villus contains a network of blood vessles and small vessels of the lympathetic system.

Front 18

Large Intestine

Back 18

colon; recovers water from the almentary canal. The waste tracts the feces that make it solid and pass through the colon..making their way into the rectum, and exit out in the anus.
