Söögitorufaasis

Söögitorufaasis refers to a specific stage in the process of deglutition, commonly known as swallowing. It is the second of the three phases of swallowing, following the oral preparation phase and preceding the pharyngeal phase. During the söögitorufaasis, the bolus of food or liquid, which has been manipulated and readied in the mouth, is propelled from the oral cavity into the pharynx. This transfer is initiated by the tongue, which elevates and pushes the bolus backward. The soft palate elevates and retracts, closing off the nasal cavity to prevent the bolus from entering the nasopharynx. The epiglottis, a flap of cartilage, also begins its descent, but the primary closure of the airway occurs in the pharyngeal phase. The söögitorufaasis is a voluntary action, meaning it is under conscious control. It is a crucial step that transitions the food or liquid from the mouth into the digestive tract, setting the stage for the involuntary movements that will guide it down the esophagus. This phase requires precise coordination of muscle movements in the tongue, soft palate, and jaw.
