nose into his middle ear
✔✔During descent, an airplane passenger is complaining that his "ears are plugged."
What aspect of the structure and function of the ear best accounts for the passenger's
complaint?
Question 6 options:
Air must be able to flow between the middle ear and the nasopharynx in order to
accommodate pressure changes.
The tympanic membrane is selectively permeable in order to accommodate pressure
changes and this capacity is often impaired during upper respiratory infections.
The eustachian tubes must remain patent to equalize pressure between the middle ear
and inner ear.
The inner ear adjusts its volume in response to atmospheric pressure, increasing during
low pressure and decreasing in high pressure. - ✔✔Air must be able to flow between
the middle ear and the nasopharynx in order to accommodate pressure changes.

body can control the levels of different hormones over time. Which of the following
statements most accurately underlies the dominant regulation process of hormone
levels in the body?
Question 8 options:
The pituitary gland is genetically programmed to stimulate and inhibit hormone
production and/or release based on needs at different points in the life cycle.
The hypothalamus ensures that hormone levels correspond accurately to the diurnal
cycle.
With input from various sensors, hormone production and release are adjusted based
on existing hormone levels.
A positive feedback cycle ensures that stable levels of hormones exist in the body over
time. - ✔✔With input from various sensors, hormone production and release are
adjusted based on existing hormone levels.
✔✔A care aide at a long-term care facility has informed a resident's nurse practitioner
that the 80-year-old woman's eyes appear to be inflamed and her eyelids are caked with

"A tumor in my brain threw off my hormone levels after I was finished with
adolescence."
"My pituitary gland produced a much higher than normal amount of growth hormone
when I was a child."
T"The high sugar levels that go along with my diabetes made my pituitary gland
overproduce the hormones that cause you to grow."

cause growth." - ✔✔"A tumor in my brain threw off my hormone levels after I was
finished with adolescence."
