Transcript Respiratory System Review

Respiratory and Excretory
System Review
1. The tubes that branch from the
trachea are the bronchi
2. The dome shaped muscle below the
chest cavity is called the diaphragm
3. During swallowing, the air passage of
the pharynx is covered by the epiglottis
4. Alveoli in the lungs are connected to the
bronchi by a network of tiny tubes
called bronchioles
5. Breathing is controlled by the chemistry
of your blood as it interacts with the
carbon dioxide
Explain what happens to carbon
dioxide and oxygen inside the
alveoli.
Alveoli fills up with oxygen and
diffuses into the capillaries (blood).
Carbon dioxide and water in the blood
diffuses out of the capillaries into
the alveoli.
Which is the correct sequence for the path of
oxygen through the respiratory system?
a) nasal cavity, bronchi, trachea, bronchioles,
cells, blood, alveoli
b) cells, blood, alveoli, bronchioles, bronchi,
trachea, nasal cavity
c) nasal cavity, blood, alveoli, bronchi, cells,
trachea, bronchioles
d) nasal cavity, trachea, bronchi, bronchioles,
alveoli, blood, cells
1. Where are the vocal cords located in the body?
larynx
2. Breathing is an involuntary process controlled
by the which part of the brain?
medulla
3.What prevents the trachea from collapsing?
rings of cartilage
4. Where does the actual exchange of gases
occur? alveoli
5. During gas exchange where does the oxygen
and carbon dioxide go?
O2 diffuses into capillaries. CO2 diffuses out
of capillaries and into alveoli.
1. Explain what happens to the diaphragm and
rib cage do during inhalation.
Diaphragm contracts (pulls down).
Rib cage expands.
2. Explain what happens to the diaphragm and
rib cage muscles do during exhalation.
Diaphragm relaxes (pushes up).
Rib cage relaxes.
Identify the structures labeled in the diagram.
trachea
bronhi
lung
diaphragm
Explain the function of the respiratory
system.
Gas exchange
between the
external
environment and
the blood
Which structures contain a ciliated mucus
membrane?
nasal cavity
trachea
bronchi
The ______ is a long straight
tube that carries air from
the back of the throat to the
lungs.
trachea
What structures trap foreign
particles and bacteria in the nose
and trachea?
cilia
1.Identify A, B,
and D.
lung
liver
kidney
Which organ
produces urea?
liver
What is the function
of D?
•Filter wastes from
blood
•Regulate water
concentration of
blood.
•Produce urine
What does organ A
excrete?
•CO2 and H2O
vapor
Which organ
detoxifies the
blood?
•Liver
What are metabolic
wastes? Examples?
•Wastes from your cells.
•CO2, H2O, salts, urea
Identify structures A, B, C, and D.
•Liver
•Ureter
•Urinary
bladder
•Urethra
Which structure produces
urine?
•Kidneys
What is the path of urine?
•Kidneys  ureters 
urinary bladder  urethra
What stores urine?
•Urinary bladder
What is the function of D?
•Releases urine from
the body.
Which human excretory structure aids in
the maintenance of normal body
temperature?
•Skin
Why is the skin also an excretory
organ?
It excretes water, salts and
urea in the form of
perspiration.
What are metabolic
wastes?
