Sympathetic nerves stimulate faster breathing in dangerous situations, such as during fight or flight response.

Answer: F
 The medulla oblongata is a part of the brainstem that controls breathing, including the rate and depth of breathing.

Answer: J
 The epiglottis is a flap-like structure that points upward, allowing air to enter the trachea but blocking the larynx during swallowing.
