Superior and Inferior Vena Cava
Deoxygenated blood flows from the body to the superior or inferior vena cava depending on which part of the body the body the deoxygenated blood comes from. If the blood comes from the upper part of the body it goes through the superior vena cava, if the blood comes from the lower part of the body it travels through the inferior vena cava. -
Right Atrium and Right Ventricle
Deoxygenated blood then flows from the superior and inferior vena cava into the right atrium. Once there the deoxygenated blood flows through the tricuspid valve into the right ventricle. -
Pulmonary Artery and Lungs
Deoxygenated blood then passes through the pulmonary valve into the pulmonary artery. From there the blood is flowing to the lungs to pick up oxygen. -
Pulmonary Vein and Left Atrium
Once the blood becomes oxygenated in the lungs it travels through the pulmonary vein back to the heart into the left arium. -
Left Atrium and Left Ventricle
Oxygenated blood then travels from the left atrium to the the left ventricle passing through the Bicuspid valve. The bicuspid valve is also known as the mitral valve. -
Left atrium and Aorta
Next the oxygenated blood travels through the aortic vlave into the aorta and from there the oxygenated blood is distributed throughout the body.
