The Respiratory System
Match the following vocabulary words to their definition.
Please write a capital letter in the blank.
A. passages that direct air into the
1.
pharynx
lungs.
B. connects the pharynx to the
2.
larynx
bronchi. It is lined with mucus
and small hairs that trap
particles.
C. smallest structure in the lungs
3.
respiration
where gas exchange takes place
between the lungs and the
blood.
D. (throat) is a long hollow tube
that connects the nose to the
trachea.
4.
cellular respiration
E. part of the throat where the
vocal cords are located.
5.
diaphragm
F. (break down of glucose for
6.
alveoli
energy) requires oxygen as a
reactant.
G. smaller branches that come off
7.
bronchioles
of the bronchi.
H. dome-shaped muscle below the
8.
trachea
lungs that causes us to inhale
and exhale.
I. the transport of oxygen from
9.
bronchi
outside the body to cells and
tissues, and the transport of
carbon dioxide and wastes away
from cells and to the
environment.

How does the structure of the alveoli help process 1 in the diagram?
A
small patterns on the surface of the alveoli correspond with the shapes
of CO2 and O2 molecules and allow them to enter
B
smooth, rounded membranes of the alveoli allow gas molecules to flow
in and our freely
C
the hollow interior of the alveoli has ample space for unlimited gas
molecules
D
thin walls of the alveoli let molecules of CO2 and O2 pass through easily
What two body systems are interacting in this diagram?
F
respiratory-excretory
G
digestive-circulatory
H
respiratory-circulatory
J
nervous-endocrine

air.
G
Inhaled air contains more oxygen and less carbon dioxide than exhaled
air.
H
Inhaled air contains more oxygen and more carbon dioxide than
exhaled air.
J
Inhaled air contains the same amount of nitrogen and carbon dioxide
as exhaled air.

This diagram shows one way in which two different body systems interact.
Which statement identifies the two body systems that are interacting and
describes what is happening.
Gases Exchanged
alveoli
21
capillaries
A
The alveoli in the respiratory system and the capillaries in the circulatory
system are exchanging oxygen and carbon dioxide.
B
The alveoli in the muscular system and the capillaries of the circulatory
system are exchanging oxygen and nitrogen.
C
The capillaries of the circulatory system and the alveoli of the excretory
system are exchanging nitrogen and carbon dioxide.
D
The capillaries of the circulatory system and the alveoli of the nervous
system are exchanging carbon dioxide and carbon monoxide.
Which of the following best
describes the alveoli?
F
G
H
J
a single tube that connects
the larynx to the lungs
22 Which body system moves
oxygen into the blood and
removes carbon dioxide from the
blood?
A
excretory
tiny sacs where oxygen and
carbon dioxide are
exchanged
B
digestive
C
respiratory
a passageway that leads
from the mouth to the top of
the trachea
D
skeletal
two folds of tissue stretched
over the airway that vibrate
to produce sound.

Organisms that require oxygen must first transfer molecules of oxygen
from their environment to their cells. In humans, which two systems are
directly involved in the transfer of oxygen from the environment to their
cells?
F
circulatory and nervous
G
respiratory and digestive
H
digestive and nervous
J
