Soc 12 - The Skeletal System Flashcards
What is the skeletal system?
The skeletal system is all your bones and joints in your body.
What is ‘protection of vital organs’?
This is where the bone acts as a shield and protects the muscles.
What is ‘muscle attachment’?
The muscles you use in sport need strong points to and attach bones provide that framework.Muscles are attached to bones bu tendons.
What is ‘Joints for movement’?
Joints allow the body to make a variety of movements.
What is ‘Storing calcium and phosphorus’?
The bones act as a store for calcium and phosphorus, two minerals that are vital for developing and maintaining the strong and healthy bones you need for exercise.
What is ‘Red and white blood cell production’?
When the oxygen content drops, or the number or red blood cells goes down, your bone marrow makes more red blood cells; if you have an infection, it makes more white blood cells.
Name the 5 functions of the skeletal system?
•Protection of vital organs
•Muscle attachment
•Joints for movement
•Storing calcium and phosphorus
•Red and white blood cell production
