I give you all my heart. Quite literally! This image was snapped during an ongoing heart transplant. The surgeon is holding a diseased, congested and failed heart while the cardiopulmonary (or heart-lung) bypass machine temporarily takes over the function of the heart and lungs during surgery, maintaining the circulation of blood and the oxygen content of the body. This patient is one step closer to get his failing heart to be replaced with another heart from a suitable donor! Photo by @scrubsallday
