Flashcards in Digestive System Deck (24):
1

What are the two methods in which food is broke down within the body?

Mechanical digestion
Chemical digestion

2

The process in which the food is physical broken down into smaller pieces

Mechanical digestion

3

Food is broken down into smaller pieces by chemical manipulation of enzymes and acids

Chemical digestion

4

What do salivary glands do?

They produce enzymes that break down carbohydrates

5

What is the alimentary canal?

This is the pathway in which food passes through your body

6

What are the functions of the digestive system?

-break down food into a soluble form so that nutrients can be absorbed into the body
-eliminate insoluble waste from the body

7

Mouth
Pharynx
Esophagus
Stomach
Small intestine
Large intestine

All found in the alimentary canal

8

Small ball of food created by the tongue when chewing food

Bolus

9

What is the pharynx?

Technical term for throat
The bolus is swallowed passes through the pharynx and travels down into the esophagus

10

What are the parts of the stomach?

Cardiac sphincter
Fundus
Body
Pylorus
Pyloric sphincter

11

The round band of muscle located at the top of the stomach

Cardiac sphincter

12

What is the fundus?

Makes up the rounded upper section of the stomach and acts as a storage space for undigested food and stomach gases that are produced by chemical digestion

13

What are the parts of the small intestine?

Duodenum
Jejunum
Ileum

14

The larger middle section of the stomach where physical and chemical digestion occurs

The body of the stomach

15

Bolus that has passed through the pylorus becomes this soupy substance

Chyme

16

What is the pylorus?

The pylorus is the last section of the stomach that stores the digested food from the body of the stomach before it passes into the small intestine.

17

Round band of muscle located at the bottom of the stomach that allows chyme to travel from the pylorus into the small intestine

Pyloric sphincter

18

What is illeum?

Illeum is also lined with villi and microvilli to help with the absorption nutrients and lipids

19

What are Small finger like projections of tissue?

villi

20

What is the pancreas considered and why?

Considered to be a gland and an organ because it produces hormones to assist with the endocrine system and enzymes help break down food in the digestive system

21

What does pancreatic amylase?

Breaks down carbs

22

What is the pancreatic lipase?

Breaks down fats

23

What is trypsin ?

Breaks down proteins

24

What is peristalsis?

Peristalsis is a series of wave-like muscle contractions that moves food to different processing stations in the digestive tract. The process of peristalsis begins in the esophagus when a bolus of food is swallowed.
