Photograph of an open pulmonary valve
Photograph of an open pulmonary valve, a semilunar valve consisting of 3 flaps (cusps) that maintains a one-way flow of blood from the right ventricle of the heart into the pulmonary artery. The pulmonary artery conducts blood to the lungs and is the only artery in the body that carries deoxygenated blood. The single artery leaving the heart divides to serve each lung, ending in the many fine capillaries that surround the air sacs (alveoli) where exchange of oxygen and carbon dioxide takes place

EDITORS COMMENTS
This print showcases the intricate beauty of an open pulmonary valve, a vital component of the human heart. Composed of three flaps or cusps, this semilunar valve ensures a unidirectional flow of blood from the right ventricle into the pulmonary artery. As captured by Science Photo Library, this image offers a glimpse into the remarkable complexity and functionality within our bodies. The pulmonary artery plays a crucial role in transporting deoxygenated blood to the lungs for oxygenation. It stands as the sole artery in our entire circulatory system that carries such blood. From there, it branches out to serve each lung individually before culminating in countless delicate capillaries surrounding tiny air sacs called alveoli. Within these alveoli lies where the magic happens – an exchange between life-sustaining gases: oxygen and carbon dioxide. This process is essential for maintaining proper levels of oxygen in our bloodstream while simultaneously eliminating waste carbon dioxide. Anatomical wonders like this open pulmonary valve remind us of both nature's elegance and its intricacy. Through scientific exploration and visual documentation by Science Photo Library, we gain deeper insights into how our bodies function at their core. Let this photograph serve as a reminder of just how extraordinary our internal systems truly are - marvels that keep us alive every single day.
