Organs {pharynx}| after mouth receive Eustachian tubes and have swallowing reflexes.
Mouth roof {palate}| is hard in front and soft in back.
Palate front {hard palate}| has bone covered by mucosa.
Palate back {soft palate}| {velum} has connective tissue and muscle. Soft palate can close opening to nasal cavity while swallowing.
Soft palate has one cone {uvula}| hanging down, which can swell, causing snoring.
At throat back are two ovoid lymph-tissue regions {tonsil}|.
After pharynx, one tube {esophagus}| goes to stomach. Opening esophagus stimulates peristalsis down esophagus, to carry bolus to stomach.
