how long is the esophagus? - Answer 20 cm long
where does the esophagus extend from? - Answer lower pharynx to the stomach
what is the UES? - Answer upper esophageal sphincter
what is the LES? - Answer lower esophageal sphincter
what pressure do the UES and LES sit at? - Answer sit closed at a very high resting
pressure
where is the esophagus situated at? - Answer situated posterior to the trachea,
pulmonary apparatus and heart
what causes aspiration? - Answer if food leaks into your trachea due to a hole between
esophagus and trachea
what is the muscle at the cervical (upper) esophagus? - Answer striated muscle
(skeletal muscle)
what is the muscle at the thoracic (middle) esophagus? - Answer mixture of striated and
smooth muscle
do we have voluntary control over the esophagus? - Answer no
what is the esophagus bounded at for the lower border? - Answer bounded at lower end
by LES (exit)
, what is the esophagus bounded at for the upper end? - Answer bounded at upper end by
the esophageal sphincter entrance
what is the stomach? - Answer large, saclike structure
what is the stomach made up of? - Answer smooth muscle, mucosa, other tissues
how many layers of muscle does the stomach have? - Answer 3
where is the stomach positioned at? - Answer positioned on the left side of the
abdominal cavity

what sphincter is the stomach known as? - Answer pyloric
how many liters does the stomach hold? - Answer 1 liter of liquid/solid
what are the forces and movements of swallowing? - Answer -passive and active forces
what do the UES and LES function as at rest? - Answer closed valves at rest
