Answer 1

St
Paul’s
Academy
Pushes
Me

Question 2

Name the 5 functions of the skeleton

Answer 2

1- STORAGE of calcium & phosphorus
2- PROTECTION of vital organs
3- ATTACHMENT of muscles
4- PRODUCTION of blood cells & platelets
5- MOVEMENT of joints

Question 3

Storage of calcium & phosphorus

Answer 3

Both minerals are vital for DEVELOPING & MAINTAIN STTONG & HEALTHY BONES(1).
For example, the storage of calcium would allow us to WITHSTAND AN IMPACT(less chance of fracturing a bone) (1).
This then allows you to have GOOD HEALTH, and CONTINUE PLAYING WITHOUT INJURY.

Question 4

Protection of vital organs

Answer 4

The hard nature of BONES means the Skeleton can PROTECT VITAL ORGANS AND CENTRAL NERVOUS SYSTEM. (1) For example, the CRANIUM PROTECTS THE BRAIN. (2) This allow a footballer to make a header and CONTINUE PLAYING WITHOUT INJURY. (3)

Question 5

Attachment of muscles

Answer 5

Provides a FRAMEWORK and ANCHOR POINTS for muscles to attach.(1) When the MUSCLE CONTRACTS, it PULLS THE BONE to move.(1) For example, when preparing to make a football, the QUADRICEPS CONTRACTS, then the knee EXTENDS.(1)

Question 6

Production of blood cells and platelets

Answer 6

RED & WHITE blood cells & platelets are made and stored in BONE MARROW. (1) red (carry oxygen to muscles), white(fights infections), platelets(helps clot blood).(2)

Question 7

Movement of joints

Answer 7

The skeleton is JOINTED to allow bones to COME TOGETHER to form LEVERS.(1) Different joints allow DIFFERENT RANGES OF MOVEMENT(1). For example, a sprinter is FLEXING their ELBOW & KNEE(hinge joint) to help produce more EXPLOSIVE MUSCLE CONTRACTIONS to cover the distance quickly.(1)
