Chapter 12 review-Heart
WORD BANK
1. The strongest pumping chambers of the heart are the ventricles
2. The function of the valves in the veins is to prevent backflow
3. The aorta carries blood to the body tissues
4. The veins carry blood to the heart.
5. The pulmonary vein carries blood from the lungs to the heart.
6. The right atrium receives blood from the body tissue.
7. The aorta and pulmonary vein are vessels with blood with a high oxygen content.
8. The atria are chambers that contract simultaneously
9. The lubb sound of the heart is associated with the closing of the tricuspid and bicuspid valves.
10. The heart sounds are made from valves closing.
11. The SA node initiates a heart beat.
12. An ECG helps to diagnose bradycardia.
13. Gas exchange occurs in the capillaries while deoxygenated blood is usually carried in the veins
14. The arteries are the vessels with the thick muscular walls and the veins contain arm-like valves
15. The number 120/80, represents a person’s blood pressure while resting.
16. The top number in the question above (120) represents the systolic pressure, while the bottom number
represents the diastolic pressure.
17. How many beats per minutes produced by the heart is referred to as pulse
18. Blood pressure is the greatest in the arteries
19. A totally blocked coronary artery is best treated with bypass surgery
20. Low blood pressure in the capillaries allows for gas exchange between the blood and the tissues.
21. Myocardial infarction is also known as a heart attack
22. Pain felt in the heart is called angina
23. The heart is nourished by the coronary artery.
24. When the heart is beating out of synch, we call that fibrillation
25. A rapid heartbeat is known as tachycardia while a slow heartbeat is called bradycardia
26. Match letters from figure with the terms below:
left ventricle:_B_
aorta: E

Chapter 14: The Respiratory System
1. The pharynx in the respiratory tract is also a passage for food.
2. The alveoli are the air sacs.
3. The bronchi branch off of the trachea and enter the lungs.
4. The larynx is also called the voice box.
5. The trachea is a single tube with ridges.
6. Gas exchange in the lungs occurs between the alveoli and the blood
7. The epiglottis closes when you swallow to prevent food from entering your trachea.
8. The muscle that is at the bottom of the chest cavity and which helps you to breathe is the diapragm
9. Another name for breathing in is inspiration
10. When you expire (breathe out) the diaphragm relaxes
11. More people die from CVD in the US than from any other cause.
