The parts are the brain, your nerves, and your spinal cord.

Fibula
How many bones are in a human skeleton?

TRUE or FALSE
Bones of the skeletal system are stronger than steel: True
Bones make red blood cells: True
The Femur is an irregular bone: False
What are the three types of muscles?
Skeleton Muscle, (close to the bones) Cardiac Muscle (in the heart) and the Smooth Muscle (they appear to be smoother than other muscles)
What are the 6 major blood types? Which one is most common?
A B AB O is the most common (Positive or negative)
How does the Respiratory System enable us to speak?
The vocal cords become tight,squeeze together and force air from the lungs to move between them. The air causes the vocal cords to vibrate and produce sound.
What role do Cilia play in our Respiratory System?
The cilia (hair like structures that are outside of cell lining the bronchus) uses their wave like motions to move the mucus up and away from the lungs and back into the throat. helps to trap and remove toxins,debris protecting the lungs and respiratory system.

What are the 3 major parts of the brain?
Cerebrum
Cerebellum
Brain stem
In which part of the digestive system does the body absorb most of the nutrients?
»
