A&P Midterm Exam Questions and
Correct Answers the Latest Update
anatomy

✓ study of the forms and organizationof body structures (morphology). Anatomists
examine the body and its organization.

Physiology

✓ study of the functions of body parts (what they do and how they do it). Physiologists
perform experiments to determine functions.

Homeostasis

✓ process of maintaining stable internal conditions such as temperatures.

Genes

✓ units of heredity that contribute to the characteristics or traits of organisms.

Explain how anatomy and physiology are related and give an example of a

human structure with its corresponding function.

✓ Structure determines function. Body parts form the human organism and each part
plays a role in the operation of the organism. The function depends on the way the
part is constructed. Examples: arrangements of bones and muscles in hands make
gripping and holding possible, heart's muscular walls contract and propel blood out
of chambers into blood vessels, teeth are shaped to break solid food into smaller
pieces

Describe how a homeostatic mechanism works and how it is regulated.

✓ How the homeotic mechanism works:
✓ A change occurs in internal environment. The receptors sense it by measuring
deviations from the set point (how far away from the normal value it is). Effectors
are activated to correct the change and return the internal environment to normal.
As the deviation lessons, the effectors are shut down. This is called a negative
feedback mechanism because the set point is corrected and the correction reduces
the action of the effectors. This is important to prevent the correction from going
too far.

✓ thin layers of cells that line the walls of the thoracic and abdominal cavities and fold
back over the organs in these cavities. They secrete a slippery serous fluid

Parietal pleura

✓ serous membrane that lines the right and left thoracic compartments that house the
lungs. This folds back over the lungs forming the visceral pleura

Visceral pleura

✓ A thin film of serous fluid separates the parietal and visceral pleural membranes

Pericardial membranes

✓ surround the heart

Peritoneal membranes

✓ membranes of the abdominopelvic cavity

Anatomical position

✓ standing erect, face forward, upper limbs at sides with palms forward.

Superior

✓ a part is above another part or closer to the head

Inferior

✓ - a part is below another part or toward feet
