Heart Anatomy

Updated: Feb 27, 2023

🟦 Deoxygenated blood enters the Heart via the ⬆️ Superior and ⬇️ Inferior Vena Cava into the ↖️ Right Atrium.

Atrial contraction pushes the blood through the Tricuspid valve into the ↙️ Right Ventricle. Remember RI in tricuspid reminds you it’s on the RIGHT.

The ventricle contracts, blood gets pushed through the Pulmonic valve into the Pulmonary artery and goes to the 🫁lungs for gas exchange.

From the lungs, 🟥 oxygen-rich blood goes via the pulmonary vein and enters the ↗️ left Atrium.

The Atrium contracts, and oxygen-rich blood gets pushed via the Mitral valve into the ↘️ left Ventricle. Remember, the L in Mitral reminds you it’s on the LEFT.

From the left Ventricle, the blood passes through the Aortic valve into the Aorta, and Oxygen Rich Blood circulates throughout the body.
