Question: what would happen if their was a whole in your heart

Hi lil monkey!
Thanks for your question! Some people can be born with a hole in their hearts, between the ventricles. This happens because in the embryo both ventricles are connected and then they close. If they don’t close properly you are born with a hole. This makes the blood with oxygen in your left ventricle mix with the blood without in your right ventricle. Luckily, many times this holes close when the heart grows and they don’t need surgery.
