- - - - Can cause heart attack or stroke
        
        heart attack occurs when blood does not reach the heart muscle.
        
        damges/ death
        
        stroke occurs when clots form in the blood vessels that supply oxygen to the brain.
        
        ruptured blood vessels and internal bleeding
  - - - pacemaker send out signals that tell the heart muscle to contract.
        
        heart pulses about 70 times each minute.
    - - to the lungs and back
      - to the body and back
  - - - Plasma
      - Red blood cells
      - Platelets
      - white blood cells
      - Blood group

- - - - Skeletal muscle: Muscles attached to bone by tendons.
      - tendons: Muscle to bone connection (MBC)
    - - Smooth muscle: lines major organs and help with their movement.
        
        `
      - Cardiac muscle: Involuntary muscle that is found only in the heart.
        
        Sarcomere: Group of Myofibrils
        
        Myofibrils: Small filaments of the muscles whorking as individual.
        
        Myosin: Stays in place.
        
        Actin: contracting the muscle.
        
        Striation: If myosin and actin overlaps it creates an striation (strips in the muscles).
        
        Nucleus: a double-membraned organelle that contains the genetic material and other instructions for the cellular progress
    - - aerobic
      - anaerobic
  - - - slow-twitch muscles
      - fast-twitch muscles
- - - - Epidermis
        
        first layer of the skin
      - Keratin
      - Dermis
        
        second layer of the skin
    - - Protection and senses
      - Vtamin production
      - Temperature regulation
    - - Cuts and scraps
      - burns
        
        Third degree burn
        
        cells in the epidermis & dermis die. Nerve cells and muscle cells are injured
        
        First degree burn
        
        cells in the epidermis are injured and may die
        
        Second degree burn
        
        cells in the epidermis die, cells in the dermis are injured and may die

        Receive signals from other neurons
        and conduct the impulses to the cell body
      - Cell boy
        
        Where the nucleus and many other cell organelles are found
      - Axon
        
        carries the nerve impulses from the cell body to other neurons and muscles
    - - Sensory neuron
        
        send impulses from the receptors in the skin and
        sense organs to the brain and spinal cord
      - Interneuron
        
        Receive signals from the sensory neurons
        and carry the impulses to the motor neuron
      - Motor neuron
        
        Carry's impulses away from
        the brain and spinal cord
        to a gland or muscle
