Respiratory System: Unit Review and Quiz
|
Unit Review
Here is what we have learned from this unit:
- The entire process of respiration includes ventilation,
external respiration, transport of gases, internal respiration,
and cellular respiration.
- The three pressures responsible for pulmonary ventilation
are atmospheric pressure, intraalveolar pressure, and intrapleural
pressure.
- A spirometer is used to measure respiratory volumes and
capacities. These measurements provide useful information
about the condition of the lungs.
- The frontal, maxillary, ethmoidal, and sphenoidal sinuses
are air filled cavities that open into the nasal cavity.
- The pharynx, commonly called the throat, is a passageway
that extends from the base of the skull to the level of
the sixth cervical vertebra.
- The larynx, commonly called the voice box, is the passageway
for air between the pharynx above and the trachea below.
- The trachea, commonly called the windpipe, is the main
airway to the lungs.
- The trachea divides into the right and left primary bronchi,
which branch into smaller and smaller passageways until
they terminate in tiny air sacs called alveoli.
- The two lungs contain all the components of the bronchial
tree beyond the primary bronchi.
- The right lung is shorter, broader, and it is divided
into three lobes.
- The left lung is longer, narrower, and it is divided into
two lobes.
Quiz
To test how much you have learned from this unit, two types
of quizzes have been created. The first type is a true-false
quiz. The quiz questions are grouped into several sets of
two questions each to reduce the size of the content on each
page. When you finish the questions in one set, click the
Next button (a right-pointing arrow icon located in the Title
Bar) to proceed to the next page.
The second type is a drag-and-drop quiz, in which, by using
the mouse pointer, you drag a textual or graphic element to
a target area to show your knowledge of the material covered
in the unit. Note that the object you are dragging will snap
back to its original position until it is placed in the correct
target area. Try to drag the object as close to the center
of the target area as possible so that the object will snap
to the target area when you chose a correct answer.
