TWO TYPES
RESPIRATION
The type of
respiration that
requires oxygen
Total energy produced
from 1 molecule of
glucose = 36 ATP
The type of respiration that
does not require oxygen to
be present
Total energy produced from 1
molecule of glucose
= 2 ATP
ALSO produces
• lactic acid
• alcohol
Forms because of an
inadequate supply of
oxygen
Result muscle fatigue
and cramping.
The mitochondria are the
engines of our cells where
sugar is burned for fuel and
the exhaust is CO2 and
H2O.
Topic: Respiration
Aim: How are humans adapted for respiration?
Recall the definition of
adaptation and
brainstorm some ideas
that apply to the
aim
Adaptations that
humans have for
respiration
include:___________

The Human
Respiratory system
Space where air enters
the respiratory system
through structures called
nostrils
3 Functions:
1. Warms
2. Moistens
3. Filters
Nostril
Contains nostrils: opening to
the nasal passages
nasal passages: lined with a
mucus membrane with cilia
Tube-like
passageway used for
air and food
“throat”
•Throat
Contains
the
epiglottis
•Flap of elastic
cartilage tissue
•
•Covers trachea
when
swallowing
food or liquids
to prevent
from choking
Choking on food is most likely
caused by an interference with the
proper functioning of the

diaphragm
nasal cavity
bronchial tubes
epiglottis
A continuation of
the airway
Lined with two
folds of tissue
called vocal cords
A.k.a. voice box
A continuation of
airway
Approximately 12cm
in length
Lined with mucous
and cilia
a.k.a. windpipe
Trachea
Surrounded by
cartilage
To prevent
collapsing
2 short tubes used as
airway
Branches of the
trachea
Bronchi – plural
Bronchus -singular
Bronchi
We have two
lungs!!!!
Topic: Respiration
Aim: How does respiration occur?
Explain three
similarities
between the
human respiratory
system and a
bundle of grapes
Grapes are
Similar to our
respiratory
system
because:
Microscopic
branches of the
bronchi
Each branch ends
with an alveolus
Alveoli- plural
Alveolus - singular
Tiny air sacs
Surrounded by
capillaries
Where the gas
exchange
occurs
Diagrams A and B represent structures found in the
human body. Diagram B represents the functional
unit of which structure represented in diagram A?

The respiratory system includes a
layer of cells in the air passages
that clean the air before it gets to
the lungs. This layer of cells is
best classified as
1.a tissue
2.an organ
3.an organelle
4.an organ

The exchange of
gases between
the organism and
its surrounding
environment.
Done by inhaling
and exhaling
The exchange of
gases between
the respiratory
system and the
circulatory
system
Through the
capillaries
Gas exchange
occurs
because of
diffusion
Oxygen
diffuses into
the blood (out
of alveoli)
Carbon
dioxide
diffuses out of
the blood
(into alveoli)
The diaphragm is
a sheet of muscle
tissue that lines
the bottom of the
chest cavity
As the diaphragm
moves up, the ribs
move down and
in. This creates a
smaller chest
cavity and that
forces air out of
the respiratory
system which is
known as
exhalation
As the diaphragm
moves down, the
ribs move up and
out. This creates a
larger chest cavity
and that forces air
into the
respiratory system
which is known as
inhalation
What controls
that action of the
diaphragm?
