1. The heart anatomy and blood pressure

2. The heart Involuntary muscle a bit larger than a man’s fist
Slightly left of the sternum, between second and fifth ribs
Each half has two chambers, the atrium (upper) and ventricle (lower)
Arteries to body from heart
Veins to heart from body

3. Blood flow through heart
Three veins in right atrium blood return to heart
Inferior vena cava
Superior vena cava
Coronary sinus (from walls of heart)
Pulmonary artery from right ventricle
Oxygenate blood
Exchanged carbon dioxide

4. -aortic reflex slows heart when pressure gets to high
Sensors
-aortic reflex slows heart when pressure gets to high
-Cartoid sinus reflex increases the heart rate when the pressure becomes to low

5. Chambers Chambers on the right relate to the lungs (pulmonary)
Chambers on the left (systemic)

6. Valves Tricuspid – right – to R ventricle from L atrium
Bicuspid – left to L ventricle from L atrium
Semilunar valves – aorta to body
**keeps blood one way
