3 Parts of Pericardium
|
1. parietal pericardium
2. visceral pericardium: covers heart surface 3. pericardial cavity: contains pericardial fluid |
|
|
3 Layers of heart wall
|
1. epicardium = visceral pericardium
2. myocardium = cardiac muscle 3. endocardium = endothelium + connective tissue |
|
|
Chambers of heart
|
1. atria: receive blood into heart
a. right atrium b. left atrium 2. ventricles: eject blood out of heart a. right ventricle b. left ventricle |
|
|
Large blood vessels
|
1. arteries: carry blood away from heart
a. pulmonary b. aorta 2. veins: carry blood towards heart a. pulmonary b. vena cava |
|
|
Valves
|
1. atrioventricular: have chordae tendineae attached to papillary muscles
a. tricuspid b. bicuspid (mitral) 2. semilunar a. aortic b. pulmonary |
|
|
Pathway of blood through heart
|
vena cava --> right atrium --> tricuspid valve --> right ventricle --> pulmonary valve --> pulmonary arteries --> lungs --> pulmonary veins --> left atrium --> bicuspid (mitral) valve --> left ventricle --> aortic valve --> aorta --> most body tissues except lungs --> (vena cava)
|
|
|
Coronary circulation
|
aorta --> coronary arteries --> capillaries in myocardium --> cardiac veins --> coronary sinus --> right atrium
|
|
|
Disorders of coronary circulation
|
1. atherosclerosis: disorder in which fatty deposits form in an artery
2. ischemia = decreased blood flow 3. angina pectoris = chest pain 4. myocardial infarction = death of part of myocardium |
