2 body systems (SA)

• Skeletal system purpose?


  Movement: provides points of attachment for muscles

  Protection: bones of the skull protect your brain and your ribs protect your lungs

  Makes Blood: red and white blood cells are formed by tissue called marrow, which is the centre of the bone

  Storage: bones store, minerals, such as calcium and phosphorus
• Skeletal system organs (LTC, bones)

  Ligaments: connective tissue holds bone at the joint

  Tendon: attaches muscles to bones

  Cartilage: it acts as a cushion between bones and a joint and protect the bones

  Bones support the body and are living, which means they need a supply of nutrients and oxygen
• Homeostatic purpose of the skeletal system


  When blood levels of minerals are too low bones release some of the minerals back into the blood
• Circulatory system purpose


  -Transports oxygen and nutrients to the tissues

  -carries CO2 and waste products away from tissues

  -plays a role in temperate and fluid regulation

  -protects the body from bacteria and other dangers
• Circulatory homeostatic purpose?


  supplying/pumping blood and oxygen to all cells throughout the body, regulating pH, water homeostasis, temperature, and blood sugar levels.
