SKELETAL SYSTEM
The skeletel is the framework on which the rest of the body is built. Bones also play a role in the other body systems: red & white blood cells grow & develop in fatty inner tissue known as a red marrow. The minerals stored in the bones, especially calcium, are released when the body needs them.
CARDIOVASCULAR SYSTEM
Most it basic function is to pump blood around the body, & a pause of more than just a few seconds will result in loss of conciousness. All body organs & tissues need a supply of oxygenated blood & removal of waste products. The delivery system can adapt swiftly to changes in demand.
NERVOUS SYSTEM
The brain is the seat of both consciousness and creativity. Through the spinal cord & nerve branches , the brain also controls all body movement. The nervous system works with endocrine glands to monitor & maintain other systems.
ENDOCRIN SYSTEM
Hormones are chemicals messengers secreted by the endocrine glands & some other organs. They circulate in the blood & other body fluids, & help the body to maintain an optimal internal enviroment. The endocrine system initiates the changes that takes place at puberty, & governs many of those that are associated with ageing, including the menopause.
IMMUNE SYSTEM
The immune system defences help to provide vital protection against infectious disease & malfunctions of the internal body systems. In a healthy person, the intricate interrelationship of physical, cellular, & chemical defences can help protect against many threats. Poor general health lowers the body's resistance.
