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 ATPALSO 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.

The Human Respiratory system Space where air
enters the respiratory system through structures called nostrils 3 Functions:
1.Warms 2.Moistens3.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”
• 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
1. diaphragm 2. nasal cavity 3. bronchial tubes 4. epiglottis
A continuation of the airway
Lined with two folds of tissue called vocal cords
A.k.a. voice box
A continuation of airwayApproximately 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 – pluralBronchus -singular
Bronchi
We have two lungs!!!!

Aim:
Respiration
How does respiration occur?
Explain three similarities
between the human
respiratory system and a
bundle of grapes
Grapes areSimilar to our
respiratory system because:
Microscopic branches of the bronchi
Each branch ends with an alveolus
Alveoli- pluralAlveolus - singularTiny air sacs
Surrounded by capillaries

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

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? Your Brain!!!!!!!!
