NU 503 Cardiac physiology
Leading cause of death globally
heart disease
leading cuase of hospitalzations
heart failure
diastole
resting state in which heart is filling
systole
contraction and ejection of blood systemically
cardiac output
CO = HR x SV
Average CO
5L/min
CO output increase with strenuous activity
4-5x increase
Right side heart valve
tricuspid
right side of the heart function
pumps deoxygenated blood into the pulmonary circulation
left side heart valve
mitral (bicuspid)
left side heart function
pumps oxygenated body into systemic circulation
Atrioventricular valves
Connects atrium to ventricles
tricuspid valve
bicuspid (mitral) valve
Tricupid valve
connects RA to RV
Bicuspid valve (mitral)
connects LA to LV
Semilunar valves
, connect outflow path to ventricles
pulmonary valve
aortic valve
pulmonary valve (pulmonic)
connects RV to pulmonary artery
Aortic valve
connects LV to aorta
Right side of heart blood flow
1. SVC, IVC
2. Right atrium
3. Tricuspid valve
4. Right ventricle
5. Pulmonary semilunar valve
6. Pulmonary trunk
7. L/R Pulmonary arteries
8. Lungs
Left side of the heart blood flow
1. 4 pulmonary veins
2. left atrium
3. mitral valve
4. left ventricle
5. aortic semilunar valve
6. aorta
7. systemic circulation
Pericardial Sac Fibrous and Serous layers
outer fibrous pericardium
inner serous pericardium
Inner serous pericardium layers
parietal layer
visceral layer (epicardium)
pericardial space
the narrow space between the visceral pericardium and the parietal pericardium - normally contains
a small amount of lubricating fluid
constrictive pericarditis
Abnormal thickening of the pericardial sac
pericardial effusion or cardiac tamponade
excess fluid
