A system is made up of several organs and tissues that work togetherto carry out a particular job(s).
The heart, together with other organs such as the blood vessels, form the circulatory system.
The biceps, triceps and all the other muscles of the body form the muscular system.
Body Systems
The body has several systems which are involved in sport.Can you name them?
Circulatory RespiratoryMuscular
SkeletalDigestive Hormonal
Nervous
Body Systems involved in Sport & Exercise
We have already looked at the physiology (function) of the body when we studied the CIRCULATORY and RESPIRATORY systems.
We will now look at the structure of the body, and in particular:
1.BONES
2.FUNCTION OF THE SKELETON
3.JOINTS
4.MUSCLES
WHAT ARE THE FUNCTIONS OF THE BONES AND THE SKELETON ?
1.MOVEMENT
2.PROTECTION of vital organs.
3.THE PRODUCTION OF BLOOD in the Bone Marrow.
4.POSTURE
Protection
The hard nature of bone means that the skeletoncan protect the more delicate parts of the body.
Examples:
The cranium (skull) protects the soft tissue of the brain.
The rib cage protects the delicate heart and lungs.
Without the skeleton, the body would beflabby and shapeless.
Examples:
The bones of the legs support the body.
The vertebrae support the head.
Support
The skeleton is jointed to allow us to move whenthe muscles attached to them contract.
Example:
The bones and joints work with muscles to enable us to walk, jog and sprint.
Movement
The vertebrae allow us to bend, stretch and rotate our body.
Red and white blood cells are made in red bone marrow which is found at the ends of the femur and humerus and in the ribs, sternum, pelvis and vertebrae.
Femur:Located in the upper part of the leg.
Humerus:Located in the upperpart of the arm.
