Main Heart Blood Vessels in 3D | Deoxygenated and Oxygenated Pathways 🫀

The superior vena cava and inferior vena cava return deoxygenated blood to the right side of the heart, while the pulmonary arteries carry that same deoxygenated blood from the right ventricle to the lungs. 🫀 This makes the pulmonary arteries a key exception, because arteries do not always carry oxygen-rich blood. In contrast, the pulmonary veins bring oxygenated blood back from the lungs to the left side of the heart, and the aorta sends that oxygen-rich blood from the left ventricle to the rest of the body. 🔬 These major vessels form the core highway of circulation and explain how blood moves through the pulmonary and systemic circuits in a continuous loop. The venae cavae deliver blood from the upper and lower body, the pulmonary arteries connect the heart to the lungs for gas exchange, the pulmonary veins return freshly oxygenated blood, and the aorta distributes it under high pressure to the body’s tissues. 📚 This anatomical arrangement is one of the most important foundations for understanding cardiac circulation, blood oxygenation, and why the pulmonary vessels are considered the classic exception to the artery-vein rule. ────────── 🎥 Video created by 🩺 Dr. Bahaa N.
