What is being demonstrated in the tubes below?
3
Absorption of nutrients into the blood stream
4
The figure best illustrates?
5

• Why starch needs to be digested.

6

• The process we performed in class with balloons
  is best described as?

7

• Passive transport
• or diffusion

8

• The process illustrated in the
• Figure is best described as?

9

• Active transport

10

• The total surface area of the rectangular prism
  in the figure is?

11

• 138 cm2

12

• What do you think amylase will do when you mix it
  with a starch solution?

13

• Amylase will break starch into simple sugars.

14

• Based on the lab we did in class what would the
  results be in the table below.

15
(No Transcript)
16

• This is mechanical digestion in the mouth.

17

• What is chewing

18

• This is what softens and moistens food in mouth?

19

• What is saliva?

20

• Salivary glands secrete this enzyme into the
  mouth?

21

• Amylase

22

• What is the function of HCl (Hydrochloric Acid)
  in the stomach?

23

• Lowers the pH of the stomach contents to activate
  the pepsin

24

• What nutrient starts its digestion in the stomach?

25

• Protein

26

• How does your body use protein?

27

• To repair tissue and build muscle

28

• Gastric juice is made of_______________and_______.
  It is found in the _____________.

29
Gastric juice is made of__HCl and pepsin_and
found in the ___Stomach____.
30

• Circular, Longitudinal, and Diagonal muscles work
  together to achieve mechanical digestion in this
  organ

31

• What is the stomach?

32

• Why are active and passive transport both needed
  in the absorption of digested nutrients into
  the body?

33

• absorption sometimes requires cellular energy
• and/or
• not all nutrients can be absorbed by diffusion

34

• What helps increase the amount of nutrients
  absorbed in the small intestine?

35

• What are villi and microvilli?

36

• This alkaline/basic solution helps neutralize the
  acidic stomach juice, when it enters the duodenum

37

• What is pancreatic juice?

38

• Fat is broken down in this organ.

39

• What is the small intestine?

40

• This organ has the largest internal surface area
  of the digestive system to absorb nutrients

41

• What is the small intestine?

42
What occurs in the colon (large intestine) that
our body needs in order to work properly.
43

• Transport
• undigested waste
• absorb water
• absorb minerals

44

• Why does our body need water to function properly?

45

• It transports nutrients and waste in our body

46

• What is the difference between large intestine
  and colon?

47

• Nothing, they are synonymous (same thing)

48
Dead cells, undigested food, and bacteria are
stored here
49
What is the Rectum?

50

• How does food move through the digestive tract?

51

• Peristalsis

52
Final Jeopardy

• Digestive System

53
Final Jeopardy

• Select an organ and explain everything you know
  about it
