propels materials along the length of the
digestive tract by coordinated contractions of the circular
and longitudinal layers.

movements primarily involve the circular
muscle layers. These activities churn and mix the contents of
the digestive tract, but do not produce net movement in a
particular direction. (only in small intestine)

The first part of mechanical digestion is

The common space used by both the respiratory and digestive systems is the

Which tunic of the alimentary canal contains the lamina propria?

Check all that are characteristics of the esophagus.

The mucosa is composed of thick, nonkeratinized stratified squamous epithelium.

The two layers of muscle in the superior one-third of the muscularis are skeletal.

Check all that are a function of the esophagus.

Movement of a bolus of food from the pharynx to the stomach.

Prevent materials from returning from the stomach.
