Teacher Notes
Links to videos appear in THIS color. The first video is a comprehensive
video of all major organ systems and homeostasis. Other videos are specific
is organ systems or homeostasis and should be used based on the needs of
students.
The table on the student packet can be completed in a variety of formats.
It is recommended that table be complete using gradual release. (The
teacher models an example, students direct the teacher to create another
example, teacher directs students to create an example, students work in
groups to create examples, students individually create examples.)

Organism
There are eight (8) major human body systems. (Dr.’s R Nice)
D - Digestive System
R - Respiratory System
S - MusculoSkeletal System
R - Reproductive System
N - Nervous System
I – Immune System
C - Circulatory System
E - Excretory System
Musculoskeletal (Muscular/Skeletal) System
BrainPop Video!
There are three types of muscles:
Skeletal (Voluntary),
Smooth (Involuntary),
Cardiac (Involuntary).
Functions:
Control movement.
Skeletal System
BrainPop Video!
Structures:
Composed of :
1.
bones,
2.
cartilage,
3.
ligaments, and
4.
tendons.
Functions:
1.
provides movement,
2.
protection,
3.
shape,
4.
support
5.
produces red blood cells.
How do the muscular and skeletal
systems work together?
Digestive System
BrainPop Video!
Structures: Mouth, pharynx,
esophagus, stomach, smallintestines, large- intestines,
rectum, anus, liver, pancreas,
gall bladder, appendix.
Functions:
To digest food
provide nutrition to the body
remove the waste from the body.
Excretory System
Includes many systems such as
digestive, respiratory, skin and
urinary system.
Urinary system
is considered the Excretory system.
Structures: Kidenys, ureters, urinarybladder, urethra.
Functions: Removes waste in the form
of urine which consists of
urea, water and other salts.
How do the digestive and execratory
systems work together?
Respiratory System
Functions:
Breathing brings oxygen into the lungs
Removes carbon- dioxide
Provides oxygen to red blood cells
Cellular respiration:
converts oxygen and glucose into carbon dioxide,
water and energy
Is the reverse process of photosynthesis (plants)
Respiration:
C6H12O6 + 6 O2 6 CO2 + 6 H2O + ENERGY
Photosynthesis:
6 CO2 + 6 H2O + ENERGY  C6H12O6 + 6 O2
Circulatory System
Function
Heart:
Red blood cells:
•
provides oxygen & nutrients to body
cells:
fights diseases (Immune System)
How do the respiratory and circulatory
systems work together?
Nervous System:
Structures:
Central Nervous System (CNS): Brain + Spinal cord
Peripheral Nervous System (PNS): Nerves
Functions: Responds to stimuli to maintain Homeostasis.
Immune System
Structures - Body has 3 lines of defense:
skin, breathing passages, mouth and stomach.
Functions: It is a defense mechanism
of the body. It fights diseases.
Bacteria, viruses and fungal infections
Reproductive System
Structures: Glands, and hormones.
Functions: Endocrine system produces chemicals that control
many of the body’s daily activities as well as long
term changes such as growth and development.
Reproductive System
Structures: Ovaries, testes, eggs, sperms.
Functions: Sexual reproduction involves the
production of eggs by the female and sperm
by the male, which join together during
fertilization.
