Question

Which part of our body closes when we swallow food​

Answer 1

The epiglottis is a flap of cartilage that guards the larynx during swallowing. So we see that during the act of swallowing, all undesired routes are blocked off. The tongue blocks the mouth, the soft palate closes off the passage to the nose and a flap called the epiglottis flops over the passage to the lungs.
