How is each chapter of W iley
Anatomy and Physiology
Student engagement requires more than just providing visuals, text, and interactivity— it entails
motivating students to learn. Student engagement can be behavioral, cognitive, social, and/or
emotional. It is easy for a student to get bored or lose focus when presented with large amounts
of information, and to lose motivation when the relevance of the information is unclear. Wiley
Visualizing and
work together to organize course content into manageable learning
objectives and relate it to everyday life. The design of
is based on cognitive science,
instructional design, and extensive research into user experience. It transforms learning into an
interactive, engaging, and outcomes-oriented experience for students.
The content in Wiley
Visualizing Anatomy and Physiology
is organized in learning
modules. Each module has a clear instructional objective, one or more examples, and an opportunity
for assessment. These modules are the building blocks of Wiley
Visualizing Anatomy and Physiology.
Each chapter engages students from the start
Chapter opening text and visuals introduce the subject and connect the student with the
material that follows.

The Respiratory System
ountain climbingcan be a dangerous sport.
As you climb, ascending higher and higher
through the Earth's atmosphere, the atmospheric
pressure decreases. As the atmospheric pressure
decreases, so does the concentration of oxygen
in the air. Climbers can experience dizziness and
may even faint if the oxygen concentration gets
too low. To cope with the effects of high altitudes,
climbers make extended stops in base camps
located at various altitudes along the way to their
destination. During these rest stops, their bodies
adjust (acclimate) to the decreased oxygen levels.
As they are acclimating, their breathing becomes
rapid and their hearts beat faster. Climbers also
use bot led oxygen to counteract the deficit.
The same effects can be felt when acclimating
to a high-altitude city such as Denver, Colorado,
the "Mile-High City” When visiting sports teams
from cities at lower altitudes play the home teams
in Denver, they often travel to the city early to give
their players a chance to acclimate, in addition,
they supply oxygen on the sidelines. Others who
experience high altitudes include fighter pilots,
astronauts, and passengers and crew members on
commercial flights, commercial aircraft and space
vehicles must maintain pressurized cabins so
that their passengers have sufficient oxygen, and
fighter pilots wear oxygen masks.
In this chapter, you wil learn how your body
takes in oxygen and removes carbon dioxide via
the respiratory system. Let's take a look at this
amazing system that permits your body to make
use of the oxygen from the air through mechanical
ventilation and gas exchange.
