Transcript Body Systems Unit Review part 2

7.12 Organisms and Environments. The student knows that living
systems at all levels of organization demonstrate the complementary
nature of structure and function. The student is expected to:
(B) Identify the main functions of the system of the human
organism, including the circulatory, respiratory, skeletal, muscular,
digestive, excretory, reproductive, integumentary, nervous, and
endocrine systems. (Supporting Standard)
(E) Compare the functions of a cell to the functions of organisms such
as waste removal.
 FUNCTION OF SYSTEM: To provide the


body with oxygen (O2) and remove
carbon dioxide (CO2) from the body.
Allows the body to breathe- inhale and
exhale
ORGANS: lungs, trachea, bronchi,
bronchioles, alveoli, pharynx,
nose/mouth, and diaphragm (a muscle)
COMPARISON TO CELL FUNCTION: This
system is similar to the cell membrane
allowing cretin things in to and out of the
cell.
 FUNCTION OF SYSTEM: To transport and


deliver materials throughout the body.
The heart pumps blood, circulating it
between the body heat and lungs.
ORGANS: heart, blood vessels: artery,
veins, capillaries, and bloodtechnically it’s a tissue!
COMPARISON TO CELL FUNCTION: This
system would be similar to the functions
of a golgi body with in a cell identifying
and delivering materials.
 FUNCTION OF SYSTEM: To protect you
from infections and foreign materials and
helps regulate body temperature.
 ORGANS: skin, hair, nails
 COMPARISON TO CELL FUNCTION: This is
similar to the cell membrane keeping
things out of a cell.
 FUNCTION OF SYSTEM: To provide the


body with the ability to move. Skeletal
muscles move bones, smooth muscles
moves materials though internal organs,
and cardiac muscle keep your heart
beating.
ORGANS: Muscles, there are many!
Examples: bicep and triceps (tendons
too)
COMPARISON TO CELL FUNCTION: Some
single celled creatures have small hairs
called flagella that allow them to move.
 FUNCTION OF SYSTEM: To provide the


body with a framework of support and
structure, stores minerals, allows for
movement, and manufactures new red
blood cells.
ORGANS: Bones (cartilage and
ligaments
COMPARISON TO CELL FUNCTION: With
multiple functions it could be compared
to the cell wall, the Endoplasmic
reticulum, vacuole, and or the cytoplasm.
 FUNCTION OF SYSTEM: To breakdown


food into simple nutrients that the body
can use. This system mechanically and
chemically digest food so it can be
absorbed and used in the body.
ORGANS: mouth, esophagus, stomach,
small & large intestine, gallbladder, liver,
pancreas.
COMPARISON TO CELL FUNCTION: This
system is most similar to the lysosome
that digest cells waste and removes it
from the cell.

FUNCTION OF SYSTEM: To remove waste from
the blood. Kidneys constantly clean blood
as it circulates through them.

ORGANS: kidneys, ureters, bladder, urethra

COMPARISON TO CELL FUNCTION: this system
is similar to the lysosome because it
removes waste and also similar to the cell
membrane because blood must pass
through the filter like going through the cell
membrane
 FUNCTION OF SYSTEM: To produce

chemical messages that regulate and
control the growth and development of
the body.
ORGANS: Pituitary, thyroid, thymus,
adrenal, testes (Males), ovaries (Female),
pancreas
 COMPARISON TO CELL FUNCTION: This is
similar to the endoplasmic reticulum in
how it makes new materials and send
them throughout the cell
 FUNCTION OF SYSTEM: To send and
receive electrical messages throughout
the body. To control the functions of the
body.
 ORGANS: brain, spinal cord, nerves
 COMPARISON TO CELL FUNCTION: This
system would be similar to the nucleus
of a cell- controlling all the activities that
that place.
