Sides and tip of the tongue are anchored to the alveolar ridge.Tongue elevation progresses sequentially more posteriorly to push the bolus backward.Anterior to posterior rolling action of the midline of the tongue.Bolus is moved posteriorly due to the midline of the tongue sequentially squeezing against the hard palate.Oral Transit Phase begins when the tongue begins posterior movement of the bolus.

Held between tongue and anterior hard palate.Individual differences as to bolus placement.Liquid held in oral cavity prior to oral transfer.Labial seal prevents food from spilling out of the oral cavity anteriorly.Salivation has begun (helps create bolus and break down food).Oral cavity is moist, mouth closed, nostrils open.Lips / teeth / tongue remove bolus from utensil.Food / drink introduced into the oral cavity.Sensory recognition of food approaching the mouth.Bolus is positioned on the tongue for transport.Food is chewed and mixed with saliva to form a bolus.

The food is manipulated (masticated if a solid) into a cohesive unit (referred to as a bolus) in preparation for the remaining phases of the swallow.
