Powering The Human Body

Resource 3.)Food
Functions
Oxygen is used to create
ATP through cellular
respiration, which provides
energy to almost all of the
cells in the body.
Regulate temperatures, carries
nutrients to cells, moistens
tissues, and dissolves minerals,
and removes waste.
Provides energy and
nutrients to the
different parts of the
human body, and
helps with cell growth.
Body Systems
Involved
Respiratory system,
Circulatory system,
Nervous system, Lymphatic
system, and Muscular
system
Circulatory system, Digestive
system, Muscular system,
Cardiovascular system, Nervous
system, Endocrine system, and
Integumentary system.
Digestive system,
Nervous system,
Lymphatic system,
Skeletal system, and
Muscular system.
Environmental
Factors
Temperature-higher
temperatures require more
oxygen intake to provide
means of energy to the cell
than cooler temperature
would. Altitudes-higher
altitudes require more
oxygen intake than lower
altitudes. And the weather
would also influence
oxygen intake.
Temperature-warmer
temperatures would require
your body to use more water to
cool itself, causing you to lose
more water faster, in cooler
temperatures you do not need
as much water. Altitudes-in
higher altitudes you use more
water than in lower altitudes.
Temperature-higher
temperatures require
you to consume more
food for energy than
lower temperatures
would.
Personal/Human
Factors
Physical illness-illnesses
such as asthma and other
respiratory problems
would influence oxygen
intake. Age, and lifestyle
choices would also
influence oxygen intake.
Gender and Age-females and
children have typically less
storage of water in their body
than males, meaning they would
need more water intake.
Activity level- if you are exerting
yourself and being physical
active you would need more
water than someone who was
not as active. Metabolismsomeone with a lower
metabolism would process
water slower, causing them to
need less water than someone
with a higher metabolism.
Illness-someone who
had a disorder such as
diabetes would
require more food or
a specific intake than
someone who did not
have the disorder. Fat
storage would also
play a role in the
amount of food
intake. Lifestyle
choices and previous
physical activity
experience would also
play a role.
