What is the path of blood through the heart
Superior/Inferior Vena Cava -> Right Atrium -> Tricupsid Valve -> Right Ventricle ->Pulmonary Valve -> Pulmonary Atery ->Pulmonary Veins -> Left Atrium -> Bicupsid Valve -> Left Ventricle -> Aortic Valve -> Aorta
What is the “lub” sound
AV valves closing
mitral & tricupsid valve
What is the “dub” sound
semilunar valves closing
aortic & pulmonic valve
What is the difference between pulmonary vs systemic circulations
Pulmonary circulation is DEOXYGENATED blood to the lungs.
Systemic circulatoion is OXYGENATED blood to the tissues.
Define systole vs diastole
Systole is the CONTRACTION of the heart chamber.
Diastole is the RELAXATION of the heart chamber.
What is normal BP
120/80
Define myocardium
- middle thickest layer
- made up of cardiac muscle tissue
Define pericardium
- covering of the heart
Define fibrous pericardium
- tough outer layer of the heart
- surrounds double layered serous membrane
What is serous membrane
- internal
- composed of the visceral & parietal (visceral is the deepest)
What fluid reduces friction
pericardial fluid
In pulmonary circulation what color are the arteries & veins
arteries are blue
veins are red
In systemic circulation what color are the arteries & veins
arteries are red
veins are blue
How does blood get back
contraction of skeletal muscles & valves
Where is most of blood found?
in the veins
