1
The 3 layers of the heart walls.
2
Pericardium Myocardium Endocardium
3
Disorder resulting from “leaky” heart valves.
4
Heart Murmur
5
Heart chambers that receive incoming blood.
6
Atria
7
Heart chambers that send blood out from the heart.
8
Ventricles
9
Blood flow circuit from the heart to the lungs and back to the heart.
10
Pulmonary Circuit
11
Blood flow circuit from the heart to the body and back to the heart.
12
Systemic Circuit
13
Vessels that always carry blood away from the heart.
14
Arteries
15
Pressure that the blood exerts on the vessel walls when the heart is relaxed.
16
Diastolic Pressure
17
Pressure that the blood exerts on the vessel walls when the heart is contracted.
18
Systolic Pressure
19
A heart rhythm that is too slow.
20
Bradycardia
21
A heart rhythm that is too fast.
22
Tachycardia
23
A heart rhythm that has all of the appropriate waves.
24
Sinus Rhythm.
25
The valves between the atria and ventricles.
26
Cuspid Valves.
27
The valves between the ventricles and the outgoing vessels.
28
Semilunar Valves
29
The vessels in which gas exchange between the blood and body cells happen.
30
Capillaries
31
The four major components of blood.
32
Plasma Erythrocytes (RBC’s) Leucocytes (WBC’s) Platelets
33
The site at which erythrocytes carry oxygen.
34
Hemoglobin
35
The major function of the lymphatic system.
36
To return fluid lost through the blood vessels back to the blood.
37
The two major components of the lymphatic system.
38
Lymph Vessels Lymph Nodes
39
The major functions of: 1) Leucocytes 2) Erythrocytes
40
1) Leucocytes – fight disease 2) Erythrocytes – carry oxygen
41
Cardiovascular disease in which the blood cannot carry sufficient oxygen.
42
Anemia
43
Cardiovascular disease in which the arterial walls become thick and narrowed leading to reduced blood flow.
44
Arteriosclerosis
45
Cardiovascular disease in which the blood supply to the heart is blocked resulting in death of some cardiac muscle.
46
Myocardial Infarction (Heart Attack)
47
Cardiovascular disease in which the heart is squeezed by too much lubricating fluid around the heart.
48
Congestive Heart Failure
49
Cardiovascular disease in which a major vessel unexpectedly bursts.
50
Aneurysm
51
The two major tracts of the respiratory system.
52
Upper & Lower
53
The 4 major structures in the upper respiratory system.
54
Nose Pharynx Larynx Trachea
55
Describe the structure of the “Respiratory Tree”.
56
Trachea Bronchi Bronchials Bronchioles Alveolar Ducts Alveoli
57
Name and function of the double layer of lining around the lungs.
58
Pleura. To lubricate the lungs against the ribcage.
59
Name and function of the small air sacs that make up the bulk of the lung tissue.
60
Alveoli. Site of gas exchange between lungs and blood.
