Q
#21 How does pulmonary circulation differ from systemic circulation?
A
Simic circulation occurs throughout the body, pulmonary circulation occurs in the heart and lungs

Q
#28 Is the function of the group of cells in the heart called the pacemaker?
A
And out signals to make the heart muscles contract

Q
#31 What is NOT a function of the cardiovascular?
A
Produce blood cells
Page-76

Q
#35 What can you infer from the fact that your heart beat faster when you exercise?
A
When you exercise your muscles need more oxygen

A
False, Arteries

Q
#45 What is pumped through blood vessels by the action organ known as the\_\_\_\_?
A
Heart
Page-73
17
Q
#47 Fluid from the blood that enters lymphatic vessels is know as\_\_?
A
Lymph
Page-69
18
Q
#48 Blood returns to the heart from the body through the bigger blood vessels called\_\_?
A
Veins cava
Page-73
19
Q
#49 Blood that is rich in oxygen leaves the heart through the blood vessel known as the\_\_\_?
A
Aorta
Page-73

Q
#52 The group of cells called the \_\_\_\_\_ regulates the rate at which the heart beats.
A
Pacemaker
Page-69

Q
#55 Substances are exchanged between the blood and body cells in the blood vessels know as \_\_\_?
A
Capillaries

Q
56
Which numbers are the pulmonary arteries?
Which are the pulmonary veins?
A
A=2, 11
V=13, 12
Page-73
23
Q
#57 Which numbers indicate atria?
A
1 and 10
Page-73

Q
#58 Which numbers represent ventricles?
A
7 and 8

```
#60
Identify structure B. What are the blood vessels called that lead into B? What is its level of oxygen content?
```
Left Atria, pulmonary veins, high in oxygen
| Page-73
26
```
#62
Identify structure G. Give the letter and name of the structure into which blood flows after leaving G.
```
G is the right atrium. After leaving G blood flows into F, the right ventricle.
Page-73
27
```
#64
Identify the structure labeled D. When blood enters structure D, is the blood low in oxygen or high in oxygen. Explain
```
D 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.

```
#65
Identify the structure labeled E. what would happen to a person who had a hole in this structure.
```
Structure E is the septum. A hole In the septum would allow oxygen-poor blood to mix with oxygen-rich blood. As a result, less oxygen would go to the body cells.
