Q

17
Q
  1. True or false; blood flows from the heart to the body through veins?
A

F, arteries

Pg. 73

18
Q
  1. Blood returns to th heart from the body through the big blood vessels called…..
A

Vena cava

Pg. 73

19
Q
  1. The circulatory system carries the needed materials oxygen and…… to the body cells?
A

Glucose, nutrients.

Pg. 76

20
Q
  1. Substances are exchanged between the blood and body cells in the blood vessels known as…
A

Capillaries

Pg. 73

21
Q
  1. What is the structure that is on the left side above the left ventricle? What structure leads into this? What is the level of oxygen content?
A

The left atrium, Pulmanory veins, high in oxygen

Pg. 73

22
Q
  1. What is the name of where blood flows after the superior vena cava? Where does the blood flow through next after this?
A

Right atrium, after that blood flows into F, the right ventricle.
Pg. 73

23
Q
  1. What is the structure that is right next to the left atrium and the left ventricle and what is its function?
A

The valve that separates the left atrium from the left ventricle. It function is to prevent blood from flowing backwards.
Pg. 73

24
Q
  1. What is the structure where blood flows goes after going to the left atrium? Is the blood high or low in oxygen explain.
A

It is the left ventricle. Blood entering the left ventricle is high in oxygen, because it has just come from the left atrium which receives oxygen- rich blood from the lungs.
Pg. 73

25
Q

What is in between the left and right ventricle? What would happen if a person had a hole in it?

A

It is the septum. A hole in the septum would allows oxygenated and deoxygenated blood to mix. As a result less oxygen would go to your body cells.
