Digestive
Objective
• Demonstrate an understanding of
the relationships within the levels of
organization in the human body.
• Describe mechanical, electrical and
chemical activities that take place
within interacting body systems.
• Provide evidence supporting the
existence of interdependent
relationships among body systems,
i.e. respiratory and excretory
systems.

Food Webs
As we look at the image behind, please note
the how the food moves and the amount of
food dependant upon the Phytoplankton.
 Now begin thinking about what happens to
the plastic in the ocean that is getting
smaller from the turbidity of the waves and
UV Degradation.
 Who can safely eat and pass the plastic?
 Who can not? What happens when that
species dies?


Respiratory system
Works on the premise, that if you
lower the pressure inside the body,
higher air pressure from outside will
travel in.
 The reverse happens when you
exhale. Pressure is increased in
body, air moves from low pressure to
high pressure.

Respiratory System
Hiccups are the result of a
stimulated/irritated phrenic nerve (the
nerve to the diaphragm) as well as
maybe the Vegus nerve
 Your Respiratory system is lined with
Mucus.
 Purpose-To catch
dirt/dust/pollen/bacteria for
eventual expectoration.

Which factor do you think is the most common
cause of ASTHMA? Pick 1
A. viral respiratory infections, such as influenza (the
flu) or bronchitis
B. bacterial infections, including sinus infections
C. allergic rhinitis
D. irritants, such as pollution, cigarette smoke,
perfumes, dust, or chemicals
E. sudden changes in either temperature or
humidity, especially exposure to cold air;
F. allergens, for people with allergies
G. emotional upsets, such as stress
H. exercise.
Bell Work Answers
 Any
answer that helps you to remember
how important breathing is, is correct!
 When it comes to asthma, ALL of the
answers are factors contributing to cases
of ASTHMA. However, they are finding as
more particulate is placed into the
atmosphere, especially things like
irritants found in Fossil Fuels and Smoke
ASTHMA
 When
it comes to ASTHMA,
there are many characteristic
appearances.
 Inflamed Brochiole tissue
 Collected mucus and puss

Carbon Dioxide and Exercise
Please
perform the
lab on Carbon
Dioxide Exchange
The Effects of Humans
on Air Pollution
 Every
Gallon of Gas releases 19
pounds of Carbon Dioxide into our
atmosphere. Air you breath.
 This causes increased numbers of
Asthma Cases.
 Also aggravates people that already
have pulmonary issues (Bronchitis,
Asthma, Cancers, Chronic Cough.)
What are some possible
solutions?
 Many
inventions are being
built to deflect the amount of
CO2 being expelled at the
ground level.
 Many electric vehicles are
ready now!
