8
Q
- How’s is the heart different from the other muscles in your body?
A
It never gets tired
9

A
Iron
10
Q
- The function of the atria is to
A
Receive blood that comes into the heart
11
Q
- What is the main difference between your ventricle section and your atria?
A
Your atria bring blood into the heart; your ventricles pump it out.
12
Q
- Place the following events in sequence: A) The left atrium fills with blood; B) the valve between the atria and ventricles close; C) Blood is pushed out from the right ventricle.
A
A,B,C
13
Q
- How long doesn’t it take for your heart to pump blood through you’re entire body?
A
About a minute
14
Q
- Where in your body can you find blood vessels.
A
Virtually everywhere
15
Q
- How does pulmonary circulation differ from coronary circulation?
A
Coronary circulation occurs in the heart; pulmonary circulation occurs in the heart and lungs
16
Q
- What tupe of tissue in the heart pump system blood throughout the body?
A
Muscle tissue
17
Q
- What is the main function of platelets?
A
Helping your blood clot
18
Q
- The function of the atria is to
A
Receive blood that comes into the heart
19
Q
- How are antigens different from antibodies?
A
Antibodies are present in white blood cells; antigens are present in red blood cells
20
Q
- Which of the following is true statement?
A
People with AB blood can receive blood from any blood group
21
Q
- If you wanted to feel pressure waves in your body, where would you touch?
A
Anywhere you’d take your pulse, like your neck
22
Q
- When is blood pressure the highest?
A
When blood is pumped out of the heart
23
Q
- Which of the following statement should about mature red blood cells isn’t true?
A
Divide to make new cell service when old ones need ro be replaced
24
Q
- The ___ side of the heart is the ___ circuito and pump se oxygen rich blood to the____.
A
Left; systemic; body
25
62. The purpose of the serous fluid in the pericardial cavity is
To decrease friction between layers of the heart as it contracts
26
69. List three types of circuits that blood flows through in the heart and briefly describe the role of each.
Pulmonary circulation= oxygen poor blood is pumped through the right side of the heart and to the lungs to be oxygenated.
Systemic= pumps oxygen rich blood through the left side of the heart and out to the rest of the body
Coronary= supplies the heart with its own oxygen rich blood to keep it nourished
27
51. What word best describes the beating of the heart and circulation of blood?
Automatic
28
70. Explain the function of the myocardium an de why it I said necessary for it to be thicker in one of the ventricles than the other.
The myocardium is the layer of the heart wall that contracts so that the blood can flow through. The left ventricle is thicker.
29
71. Describe the pathway the blood will travel through each part of the heart.
Oxygen poor blossom enters the heart through the superior and inferior vena cave. It goes through the right atrium and the tricuspid valve into her right ventricle. It passes through the he pulmonary valve into the pulmonary trunk and out to the lungs to be oxygenated. It returns to the heart via the pulmonary veins and enters the left atrium. It goes though the mitral valve into the left ventricle and then is pumped through the aortic valve and the aorta to the rest of the body.

72. Label
```
A. Superior vena cava
B. Aorta
C. Pulmonary veins
D. Pulmonary trunk
E. Tricuspid valve
F. Left Atrium

73. Describe three factors that’s cause resistance to the flow of blood through the vessels.
Bloods viscosity, the length of a blood vessel, and the diameter of a blood vessel. The diameter of a blood vessel has the greatest impact because the viscosity of blood and the length of a blood vessel remain relatively constant, where the diameter of a blood vessel and change if the vessel contracts or is blocked in someway
32
67. Define hematopoiesis
Blood cell formation. It occurs in the red bone marrow amen is regulated by a hormone called EPO
