Describe the flow of blood through the human heart, referencing the provided diagram.

The image displays a detailed diagram of the human heart, illustrating the flow of blood through its chambers and major vessels.

Here is a description of the detailed blood flow through the heart as shown in the diagram:

1. Deoxygenated blood (shown in blue) from the body enters the Right Atrium via the Superior Vena Cava (from the upper body) and the Inferior Vena Cava (from the lower body).
2. From the Right Atrium, blood passes through the Tricuspid valve into the Right Ventricle.
3. The Right Ventricle pumps this deoxygenated blood through the Pulmonary valve (not explicitly labeled but implied at the exit of the right ventricle into the pulmonary artery) into the Pulmonary Arteries, which carry it to the lungs.
4. In the lungs, the blood releases carbon dioxide and picks up oxygen, becoming oxygenated blood.
5. Oxygenated blood (shown in red) returns from the lungs to the heart via the Pulmonary Veins, entering the Left Atrium.
6. From the Left Atrium, blood passes through the Mitral (bicuspid) valve into the Left Ventricle.
7. The Left Ventricle, the strongest chamber, pumps this oxygenated blood through the aortic valve (not explicitly labeled but implied at the exit of the left ventricle into the aorta) into the Aorta.
8. The Aorta then distributes the oxygenated blood to the rest of the body.

Key anatomical structures also labeled in the diagram include:

• Interatrial septum: The wall separating the right and left atria.
• Interventricular Septa: The wall separating the right and left ventricles.
• Chordae Tendineae: Tendinous cords that connect the valve cusps to the papillary muscles.
• Papillary Muscles: Muscles in the ventricles that anchor the chordae tendineae, preventing valve prolapse during ventricular contraction.
