What bones join at the elbow?
Humerus, radius and ulna
What is the main function of flat bones
Protect vital organs
What are the 4 types of bones
Flat, long, short and irregular
What are the 6 functions of the skeleton
Support, protection, movement, shape, mineral storage, blood cell production
What attaches muscle to bone
Tendons
How does cartilage prevent injury
Acts as a vision and a shock absorber and reduces friction
What are the two types of synovial joints
Hinge and ball and socket
Definition of rotation
The circular movement of a limb around a central axis
Definition of abduction
Moving a limb away from the body’s midline
What is the definition of extension
Straightening a joint/ increasing the angle at a joint
What are the 3 types of muscle
Skeletal
Involuntary
Cardiac
Definition of agonist
Prime mover

Pathway of air
-mouth/nose
-trachea
-bronchi
-bronchioles
-lungs
-alveoli
-capillaries
-muscles
Function of alveoli
Tiny air sacs that allow for easy gaseous exchange
What is gaseous exchange
The exchange of gases from an area of high concentration to and area of low concentration across a concentration gradient
What features assist with gaseous exchange
Alveoli have large surface area, short distance for diffusion, capillaries and alveoli are one cell thick
Definition of tidal volume
The amount of air breathed in OR out in one normal breath at rest
Features of an artery
Thick walls, narrow lumen, high pressure
Features of a vein
Thin walls, wide lumen, low pressure
