LS Chapter 17 Notes
Respiratory System
Breathing – movement of air
in and out of the lungs. NO
muscles are connected to the
lungs.
Inhalation – bring air into
the lungs
Exhalation – expelling or
letting air out of the lungs.
Air Pressure
Force that drives air into
lungs. The lungs are sealed
into two sacs. At the bottom
is the diaphragm. System
works because the chest
cavity is sealed.
The diaphragm is a large
dome-shaped muscle that
plays an important role in
breathing.
Circulation
The circulatory system assists
the respiratory system
by linking the respiratory
surface in the lungs with all
cells of the body.
Circulation
 Carries raw materials for
cellular respiration
 Removes waste products
Section 2
Smoking and Your Health
Carbon Monoxide is a
colorless, odorless dangerous
gas. It binds with your
hemoglobin in red blood cells
and blocks oxygen that the
red blood cells normally
carry.
Nicotine is a dangerous
chemical found in tobacco
and over time it produces an
addiction.
Bronchitis is an irritation of
the breathing passages in
which the small passages
become clogged with mucus.
Emphysema is a serious
disease that destroys lung
tissue and causes breathing
difficulties.
Lung Cancer – cigarette
smoke contains many
chemical that cause cancer.
Tumors and growths take
away space in the lungs that
are used for gas exchange.
Atherosclerosis Some
chemicals in tobacco irritate
the walls of the blood vessels
and contribute to the buildup
of fatty material on the vessel
walls. This causes
atherosclerosis and can lead
to heart attacks.
Section 3
The Excretory System
The body collects wastes
produced by cells and
removes
them from
the body.
This is where
your adrenal
glands are
located.

6. Kidney ___________________________________________________________

Removal of Wastes;
The lungs and skin
remove some wastes
from the body.
The liver produces
urea which breaks
down proteins and it
converts part of the
hemoglobin molecule
from old red blood
cells to bile.
