- - - - using energy
- - - - and sense organs, glands and muscles (OGM)
    - - Carried out by Somatic nervous system
    - - Carried out by Autonomic nervous system
  - - - protected by the skull
  - - - Central part of neuron
    - - Cause a response in a muscle or gland
    - - Possesses numerous receptors
        
        receive messages from other cells
    - - Speeds up messages through the neuron
    - - Make synaptic contacts with other nerve cells
    - - Carries impulses away from cell body
    - - Control center of cell
      - Contains DNA
  - - - Carry impulses through spinal cord and brain
    - - Receive impulses
      - Cause responses to muscle gland
    - - Detect changes in environment
      - Sent as impulses to the interneuron
- - - - Renal Artery
        
        Dirty blood
      - Glomerulus
        
        takes everything except blood cells
      - Bowman's Capsule
        
        Urea, water, salt, glucose and amino acid
      - Proximal Tubule
        
        Glucose and amino acids are reabsorbed into blood
      - Loop of Henle
        
        Salt is pumped out
        
        Water is extracted
      - Distil Tubule
        
        Potassium is regulated from everything left
      - Collecting Duct
        
        Whats left is called Urine

      - Deals with different skils
    - - Largest part
      - Controls physical activity
    - - Coordinates
      - Muscle movement
      - Balance
    - - Automatic responses
      - Breathing
      - Heart rate
    - - Controls hunger, thirst, body temp.
      - Vital role in homeostasis
      - Releases hormones
    - - Sorts impulses
      - Directs to other parts of brain for processing
  - - - Visual
