Cardiovascular
A
Heart, blood and blood vessels
21
Q
Heartbeat
A
Contraction & relaxation of heart
22
Q
SA Node
A
Sinotrial node- natural pacemaker of the heart
23
Q
AV node- atrioventricular node
A
Transmits electrical impulse to HISS
24
Blood
Fluid tissue that transports oxygen & nutrients to body tissue
25
Heart
Hollow muscular organ located in thoracic cavity. Maintains blood flow throughout the body.
26
Percardium
Aka pericardial sac. Double walled sac that encloses the heart.
27
Walls of heart:
Epicardium, myocardium and endocardium
28
Epicardium
External layer of heart, inner layer of pericardium
29
Myocardium
Middle. Aka myocardial muscle. Creates pumping movement that maintains blood flow.
30
Endocardium
Inner lining of heart, consists of epithelial tissue, and comes into direct contact with blood as it's being pumped from the heart
31
Coronary arteries
Supply oxygen to myocardium. One pumps oxygen one removes waste/
32
Chambers of heart
Atria- upper two chambers
Ventricles - lower two chambers
33
Valves of the heart
Tricuspid, pulmonary, mitral and aortic
34
Tricuspid valve
Controls opening between right atrium and left ventricle
35
Blood vessels
Arteries, capillaries, and veins
36
Arteries
Large blood vessels that carry blood away from heart to body. Muscular and elastic.
37
Aorta
Largest blood vessel in body
38
Carotid arteries
Major artery that carried blood upward to head
39
Arterioles
Smallest branches of arteries, deliver blood to capillaries
40
Capillaries
Smallest blood vessels in body. Delivers oxygen and nutrient to cell tissue
41
Vein
Form a low pressure collecting system to return oxygen poor blood to heart
42
Venae cave
Two largest veins in body
43
Pulse
Rhythmic pressure against walls of artery caused by contraction of heart
44
Blood pressure
Measurement of amount of systolic and diastolic pressure exerted against walls of arteries
45
Systolic pressure
Occurs when ventricles contract. Highest pressur against walls of artery
46
Diastolic pressure
When ventricles are relaxed, lowest presue against artery walls
47
Plasma
Fluid that contains nutrients hormones and waste products
48
Clotting proteins
Prothrombin and fibrinogen
49
Formed elements of blood
Erythrocytes, leukocytes and thrombocytes
50
Major group of leukocytes
-neutrophils: most common WBC
-basophils: least common type of WBC
Eosinophils: destroy parasite, major role in allergic reactions.
Lymphocytes: produce antibodies
Monocytes: immunological defenses
51
Thrombocytes
Aka platelets. Smallest formed elements of blood.
52
Blood types
A, AB, B and O
53
Rh factor
Presence or absence of antigen in red blood cells
54
Blood gases
Oxygen, carbon dioxide and nitrogen
55
Congenital heart defect
Abnormalities caused by failure of heart to develop normally before birth
56
CAD- coronary artery disease
Atherosclerosis of coronary arteries that reduces blood supply to heart muscle
57
Atherosclerosis
Hardening and narrowing of arteries
58
Angina
Severe chest pain because of inadequate blood flow
59
Myocardial infarction
Heart attack by blockage of coronary artery
60
Carditis
Inflammation of heart
61
Cardiomyopathy
All disease of the heart muscle
62
Arrhythmia
Loss of normal heartbeat
