THE HEART

HEART LAYERS

• Pericardium- surrounds the heart
• Myocardium- thick bundles of cardiac muscle twisted
• Endocardium- lines the heart chambers

HEART CHAMBERS

• Right atria- Receives deoxygenated blood from the body
• Right ventricle- Pushes deoxygenated blood to bet oxygenized
• Left atria- Receives oxygenized blood
• Left ventricle- Pushes oxygenized blood to the whole body

HEART VALVES

• Semi-lunar valves- valve between a ventricle and a great vessel
• Bicuspid- the left a/v valve
• Tricuspid- the right a/v valve

CARDIAC OUTPORT FORMULA

• Is the volume of blood being pumped by the heart
• In particular by a left or right ventricle in the time interval of one minute
• One minute

ARTERIES VS. VEINS

• Arteries carry oxygenated blood except the pulmonary circuit
• Veins carry deoxygenated blood except the pulmonary circuit

BLOOD PRESSURE- SYSTOLE/DIASTOLE

• Systolic pressure is the pressure when the heart is contracted
• Diastolic pressure is the pressure of heart when relaxed
