With the help of some doctors and an ice box, your heart can survive outside of your body up to 4 hours. But don’t worry, if your heart ever does escape your body it’ll most likely be due to a transplant. This continues until the cells run out of energy, about 3 to 5 minutes. Stimulating the top part of your heart to contract which, in turn, pumps blood to the ventricles.Įven after your heart is disconnected from your body, the SA node still sends impulses throughout the organ, allowing it to pump. These impulses travel along the walls of your right and left atrium. How annoying would that be? Instead, electrical impulses in your heart are triggered by the sinoatrial node, or SA node. Without this, your brain would have to send a signal to your heart to trigger every beat. That’s because your heartbeats are sparked by your own natural pacemaker – found within your heart. Everything you need to make your heart work, is right within the heart itself. Sure your brain has to do with how fast or slow your heart rate is, but it doesn’t actually control the beat of your heart. The reason your heart survives is because it isn’t regulated by your brain. It’ll survive, but not for long without medical intervention. But let’s say your heart somehow gets taken out of your body a la Temple of Doom (may need to cut). Keep in mind, that if your brain fails then so will your heart.
But how? Your heart can beat completely independently of you as long as oxygen is provided. Your heart works so hard, it even puts in a little overtime. It’s constantly pumping blood throughout your body - delivering oxygen and nutrients to your muscles and brain in order for them to stay healthy and work properly. Your heart beats, on average, over 3 billion times during your lifetime. One thing that is true, it’s an extremely hard worker. It’s just a muscle that pumps blood to keep you alive. But in reality, none of this is true, your heart doesn’t think. It tells us who to love, makes us emotional and helps us write cheesy love songs. Pop culture might make you think your heart does a lot of things. But did you know your heart can survive without you? But for how long? And how is this medical phenomenon possible? It’s the subject of countless songs, books, poems, it even has its own holiday dedicated to it. Theres no organ more memorable than your heart. We care a lot about our hearts, and it’s not just because they keep us alive.
