Blowholes are a whale's nostril and are located on the top / back of the whale's head. Blowholes are covered by muscular flaps that keep water from entering them when the whale is underwater. In their relaxed state, the flaps cover the blowhole which leads to the whale's trachea and then onto their lungs.
