Transcript
The Skeletal System Review
What are the functions of the
skeletal system?
Circle the joints on the skeleton below.
1. Protection
2. Movement
3. Blood Production
4. Support
5. Storage
What type of connective tissue
attaches muscles to bones?
Tendons
What is a joint?
Place where two bones meet
What are some examples of moveable
joints?
Hinge, Sliding/Gliding, Ball-and-socket,
Pivot
The Muscular System Review
What are the functions of the
muscular system?
1. Movement
2. Heat
What do muscles need in order to
function? How do they get this
needed material?
ATP (energy) created in cellular
respiration
3. Protection, Pump blood
through the heart
What are they three types of muscle? What purpose does each serve?
1. Skeletal – on bone
2. Cardiac –in heart
3. Smooth – lines organs
What is the difference between flexion and extension?
Flexion – when bicep contracts and tricep relaxes
Extension – tricep contracts and bicep relaxes
How do the skeletal and muscular systems work together
(interdependently) to create movement?
Tendons attach bone to muscle and when you pull on the tendon the bone
and the muscle work together to create movement.
The Respiratory System Review
What are the functions of the
respiratory system?
Describe the process of
breathing.
Take in oxygen
Inhale the diaphragm contracts
and moves down to open chest
cavity – bringing air in
Exhale the diaphragm relaxes and
moves up – moving air out
Describe gas exchange at the alveoli.
-
Carbon dioxide diffuses into the alveoli from the oxygen poor blood in the
capillaries that surround the alveoli
-
Oxygen from the alveoli diffuses into the blood through the capillaries
and is brought to the heart and pumped to the rest of the body
Describe the role of the respiratory system in the process of cellular
respiration.
Respiratory system is responsible for providing the oxygen which is needed
for cellular respiration to occur.
Respiratory system is responsible for disposing of the waste (carbon dioxide)
created by cellular respiration where it is exhaled (expelled from the body).
The Digestive System Review
What are the functions of the digestive system?
1. Absorb nutrients
2. Get rid of wastes
3. Break down food into nutrients
What is the difference between mechanical and chemical digestion?
Explain how nutrients like glucose get into the bloodstream.
The nutrients move into the bloodstream through the capillaries that
surround the villi in the small intestine.
Describe the role that the digestive system plays in the process of
cellular respiration.
The digestive system is responsible for providing the nutrient, glucose
for cellular respiration.
