A&P 1 MIDTERM
Chapter 1
1) Know the clinical significance of the compartmental arrangement
of the thoracic viscera by the mediastinum.
The thoracic viscera is a compartment of organs in the thoracic cavity that contains important
organs, like the heart and lungs. It is important that the heart and lungs are near each other
because once the lungs receive the oxygen carrying red blood cells the body can immediately
send those cells to the heart without wasting time and send oxygen throughout the body.
2) Know the sequence of body cavities through which any kind of
tracer would travel from the heart, through the aorta, and into the
uterine artery.
The tracer will start from the pericardial cavity, to the mediastinum, and then move on through
the abdominal cavity and lastly it will exit out of the pelvic cavity.
3) Be able to discuss in detail how the body maintains homeostasis with
regard to normal body temperature.
Homeostasis is the state of maintaining the body at equilibrium. It makes sure that the body
stays at a normal temperature despite of changes inside or outside the body. When a
disruption occurs it sets off feedback systems that help restore conditions needed for health
and life. The nervous and endocrine systems bring the body’s internal environment back to
balance. The nervous system sends nerve impulses to organs that can counteract changes from
balanced state. The endocrine system includes many glands that can secrete messenger
hormones into the blood. The nerve impulses work faster than the hormones, but they both
work effectively through negative feedback.
4) Know the different planes

, A&P 1 MIDTERM
Midsagittal – cuts body in the middle, equal sides
Parasagittal – cuts body in the middle, unequal sides
Transverse – cuts body across
Oblique – cuts in 45degree angle
Frontal – cuts body front and
back
5) Know the different levels of chemical organization.
Chemical – includes smallest unit of matter (atoms) to form molecules
Cellular – molecules combine to form cells, smallest unit of living life
Tissue – groups of cells joined to perform a specific function
Organ – tissues joined together
