  • What system signals bones to release minerals?
    The nervous system
    The muscular system
    The respiratory system
    The digestive system
  • What allows the heart to pump blood?
    The lungs
    The nervous system
    The heart muscle
    The bone marrow
  • How do the skeletal and muscular systems work together?
    Muscles move bones to create movement
    Bones digest food for muscles
    Bones pump blood to muscles
    Bones control breathing
  • What is the function of bones?
    Store oxygen
    Send messages to muscles
    Control heart rate
    Provide support and structure to the body
  • What is collaboration in the human body?
    Relaxing the body systems
    Working together to create a final result
    Communicating through speech
    Producing hormones
  • Which system sends messages to muscles?
    Digestive system
    Nervous system
    Circulatory system
    Respiratory system
  • What are ligaments?
    Fluid between bones
    Tissues that connect bones together
    Muscles that move the arms
    Tissues that connect muscles to bones
  • What is the main function of the muscular system?
    To store oxygen
    To digest food
    To protect organs
    To move the body’s parts
  • What is function?
    The speed of digestion
    The structure of bones
    How something works or its purpose
    The way energy is created
  • What connects bones and muscles for movement?
    Nerves
    Tendons
    Ligaments
    Cartilage
  • Why is communication between systems important?
    It keeps cells from moving
    It slows the heartbeat
    It enables survival and coordination
    It stops blood flow
  • What is communication in the body?
    The movement of bones
    The process of breaking down food
    Exchanging information between cells and systems
    The release of energy
  • What is bone marrow?
    Hard outer layer of bone that protects muscles
    Soft tissue that connects ligaments
    Cartilage between bones
    Spongy material that makes and stores blood cells
  • How does the skeletal system help the circulatory system?
    It pumps blood through veins
    It breaks down food into nutrients
    It produces energy
    It makes red blood cells that carry oxygen
  • What is homeostasis?
    Maintaining a stable internal environment
    Breathing faster
    Breaking down food
    Producing energy quickly
  • How do muscles get oxygen and nutrients?
    Through blood vessels from the circulatory system
    From the brain directly
    From the bones
    From the skin
  • What does the skeletal system do?
    Controls breathing and heart rate
    Breaks down food
    Supports and protects the body and helps with movement
    Creates electrical signals
  • What mineral is stored in bones?
    Iron
    Glucose
    Oxygen
    Calcium
  • How many bones are in the human skeleton?
    150
    500
    300
    206
  • What is cartilage?
    Fluid that fills joints
    Tough tissue on the ends of bones for smooth movement
    Muscle that pumps blood
    Tissue that makes red blood cells
  • What are voluntary muscles?
    Muscles found only in the stomach
    Muscles that move when you choose
    Muscles that move automatically
    Muscles that pump blood
  • How do involuntary muscles help the digestive system?
    They break food into oxygen
    They move food through the intestines
    They store waste
    They stop digestion
  • How does the skeletal system support movement?
    The brain pushes bones directly
    Muscles pull on bones to move the body
    The heart pumps bones
    The skin contracts bones
  • How does the skeletal system help prevent illness?
    It produces white blood cells
    It removes carbon dioxide
    It produces hormones
    It makes oxygen
  • What are involuntary muscles?
    Muscles that move without conscious control
    Muscles that attach to bones
    Muscles that form the skin
    Muscles you move on purpose
