the head is held high, and the palms of the hands are facing forward
superior - ✅✅-Higher on the body, nearer to the head
Lateral - ✅✅-Away from the midline of the body
Superficial - ✅✅-near the surface
Posterior - ✅✅-back of body
What are planes of reference? - ✅✅-Are used to separate the body into various
two-sided portions. Sagittal planes separate the body structures into left and right
divisions, frontal into anterior and posterior divisions and transverse into superior and
inferior divisions.
, The respiratory systems main functions are? - ✅✅
-extracting oxygen from the
atmosphere and expelling carbon dioxide from the body into the air
The process of the lungs working is called what? - ✅✅-Ventilation
How many respiratory tracts are there? - ✅✅-There's an upper and lower
respiratory tract
The lower respiratory tract inludes? - ✅✅-trachea, lungs, bronchus, bronchioles,
and alveoli
✅✅
The lungs are the organs of respiration and are divided into lobes. What are the
lobes? - -Three lobes on the right and two lobes on the left
Each lobe is contained with what? - ✅✅-a tough, protective double membrane
called pleura
✅✅
Oxygen flows through the larynx into the trachea, which is the beginning of what
respiratory tract? - -Lower

rings and lies anterior to the esophagus
The trachea splits into two main branches, which are what? - ✅✅-Two branches
that enters the lungs as the right and let primary bronchi

What does total lung compacity - ✅✅-Means the total/amount of gas in the lungs
after a maximum inspiration/deep breath.
What does VC stand for? - ✅✅-vital capacity
What does vital capacity mean? - ✅✅-is the amount of gas that can be exhaled
after a maximum inspiration as in exhaling after a deep breath
✅✅-residual volume
What does RV stand for? -
What does RV mean - ✅✅-The amount of gas remaining in the lungs after a
maximum expiration
What does atelectasis mean? - ✅✅-collapse or closure of a lung resulting in
reduced or absent gas exchange
