pathway of blood

Right Side of the Heart

  1. Superior and Inferior Vena Cava (SVC and IVC):Deoxygenated blood enters the right atrium through these veins.

  1. Right Atrium: Blood accumulates in this chamber before contracting and pushing blood through the tricuspid valve.

  1. Tricuspid Valve: This one-way valve prevents the backflow of blood into the right atrium.

  1. Right Ventricle: After going through the tricuspid valve, deoxygenated blood enters the right ventricle for contraction to push it towards the lungs.

  1. Pulmonary Valve: From the right ventricle, blood pumps through this valve into the pulmonary artery.

  1. Pulmonary Artery: This artery carries deoxygenated blood to the lungs for oxygenation.

Left Side of the Heart

  1. Pulmonary Veins: Oxygenated blood returns to the heart from the lungs through these veins, entering the left atrium.

  1. Left Atrium: Blood travels through this valve from the left atrium to the left ventricle.

  1. Mitral Valve (Bicuspid Valve): Oxygenated blood enters the left ventricle through this one-way valve.

  1. Left Ventricle: The left ventricle, the thickest chamber, pumps oxygenated blood through the rest of the body.

  1. Aortic Valve: From the left ventricle, blood pumps through this valve into the aorta.

  1. Aorta: The aorta, the largest artery, carries oxygenated blood to all parts of the body.
