Transcript The Respiratory System - White Plains Public Schools

Do Now:
Work with your elbow buddy
Partner 1: Blow up balloon using 1 normal
breath.
Partner 2: Measure circumference (distance
around middle).
Compare with your table.
Now do the same with a BIG breath.
The Respiratory System
• Why do astronauts
wear space suits and
carry oxygen when
they go out in space?
Why do deep sea divers
take oxygen with
them on a dive?
The Respiratory System Functions
• The respiratory system moves oxygen
from the outside environment into the
body.
• It also removes carbon dioxide and water
from the body.
Oxygen
Carbon Dioxide
Respiration: What is it?
Respiration is the process by which oxygen and glucose (sugar) go
through a chemical reaction inside cells. The chemical reaction releases
energy that the cell uses.
oxygen +
sugar
Energy and
carbon
dioxide
Do Now: Describe what is happening in this
picture.
Use these terms: lungs, arteries, veins, blood cells, body
cells, heart, oxygen and carbon dioxide. Use scientific
vocabulary.
What is air we breathe made of?
•

•
•
Air is made up of a mixture of gases.
21% oxygen
78% nitrogen
1 % carbon dioxide, helium and other
gases.
• What is air mostly?
Do Now: On p. 18 of your packet,
sequence the pathway of air as it flows
from outside the body to the alveoli.
As air travels from
outside, it travels
(pharynx)
through the nose,
pharynx, larynx,
trachea and
bronchi and
bronchioles to the
alveoli
