A
Fiber
2
Q
- When Chyme enters the small intestine
A
Nothing occurs
3
Q
- Which nutrients are made up of amino acids?
A
Proteins
4
Q
- If you wanted to find the glands that produce salivary amylase, where would you look?
A
Under your younger
5
Q
- Where digestion of carbohydrates begin?
A
Mouth
6
Q
- What substance must be present in the stomach for pepsin to work best?
A
Hydrochloric acid
7
Q
- What digestive organs releases enzymes that help break down starches, proteins, and fats in the small intestine?
A
Pancreas
8
Q
- The process by which nutrient molecules pass through the wall of the digestive system and into the blood is called?
A
Absorption
9
Q
- What is chyme?
A
It is what food is called after it’s been digested by the stomach
10
Q
- Food is pushed through the esophagus to the stomach by the waves of muscle contraction known as absorption
A
False, peristalsis
11
Q
- Bacteria in the esophagus makes vitamin K
A
False, Large intestine
12
Q
- The breakdown of complex food molecules into simpler molecules is mechanical digestion.
A
False, chemical
13
Q
- Using the digestive system, give the names of the two organs shown in the diagram though which food doesn’t travel
A
After leaving the stomach, food enters the small intestine
14

16
Q
- Using the upper part of the digestive system, name the line or a found on the inside of the duodenum and describe the function.
A
The structures are villi, nutrient Molecules pass into cells on the surface from villus and from there into blood vessels, the villi provides a large surface for absorption.
17
Q
- Using the upper part of the digestive system, what specifically is the name of the area of the duodenum showing? In general could the duodenum perform its function without organ B, explain?
A
Without the pancreas or duodenum, that produces enzymes, we wouldn’t be able to complete chemical digestion. So the small intestine would be unable to small nutrients into the blood stream.
