A couple of questions

What initiates the swallowing reflex quizlet?

In the first stage, which is initiated voluntarily, food is chewed and mixed with saliva. Then, the tongue rolls this mixture into a mass (bolus) and forces it into the pharynx. The second stage begins as the food stimulates sensory receptors around the pharyngeal opening. This triggers the swallowing reflex.

What initiates the swallowing reflex?

The swallowing center in the medulla oblongata initiates the deglutition reflex and causes progressive contraction of the pharyngeal muscles to continue to propel the food bolus.

What mouth part helps to mix food with saliva moves food toward the pharynx for swallowing and horses taste receptor cells?

The lingual lipase begins the breakdown of fat components in the food. The chewing and wetting action provided by the teeth and saliva prepare the food into a mass called the bolus for swallowing. The tongue helps in swallowing—moving the bolus from the mouth into the pharynx.

What events take place during the swallowing reflex quizlet?

What events take place during the swallowing reflex? The epiglottis covers the larynx. Soft palate raises, preventing food from entering the nasal cavity. Muscles in the laryngopharynx relax, opening the esophagus.

Why is it possible to swallow while doing a handstand quizlet?

Why is it possible to swallow while standing on one's hands? Peristalsis pushes food along the digestive tract in the right direction.

What occurs during swallowing?

The teeth grind and chop food into tiny pieces while the glands in the mouth moisten it with saliva. Then the tongue pushes the moistened food, or bolus, to the back of the throat and down into the esophagus, which leads to the stomach.

Do swallows automatically?

Swallow function, much like breathing or blinking, is an automatic, bodily process that we rarely notice—that is, until something disrupts it.

How does saliva help in the digestion process?

Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.
