The Right and Left side of the Heart
The Heart has 4 vessels. (R to L)
Vena Cava (a vein)
Pulmonary Artery (an artery)
Aorta (an artery)
Pulmonary Vein (a vein)
The Heart has 4 valves
Bicuspid (Mitral) Valve
Deoxygenated Blood enters via the Vena cava into the Right Atria.
It is then passed through the Tricuspid valve into the Right Ventricle.
From here it is squeezed passed the pulmonary valve into the pulmonary artery to the Lungs.
Blood flow continued
Oxygenated blood enters via the pulmonary vein into the Left Atria.
The blood then passes into the Left Ventricle passed the Bicuspid Valve.
Then into the Aorta, passed the Aortic Valve, and to the body tissues.
