        Pulmonary vein - Takes blood from the lungs and into the heart.
- - - - Something that triggers and physical or behavioural response.
        
        Sunlight acting as a stimulus for plants to photosynthesis
    - - Result of a stimulus
        
        Moving your hand away from a hot plate
    - - Pathway which impulses travel along to be transmitted from a receptor
        
        If you touch something hot an impulse travels along a reflex arc to a sensory neurone then to a relay neurone which is located in the spinal cord.
    - - Neurone triggered by actions of the environment
        
        Touching a hot surface with your fingertips
    - - Structure on the surface of a cell that detects physical stimuli and turn them into electrical impulses
        
        Receptor cells reacting to chemicals in food on the surface of the tongue
    - - Effectors produce a response to a stimulus
        
        Muscle contracting to move your arm away from a hot plate
  - - - LH triggers the release of and egg from the ovary's and FSH matures the egg ready for it to be fertilised by the sperm
    - - Helps development of a babies organs and correct function of the placenta.
    - - Prepares the uterus for a potential fertilised egg - Also prevents the contraction of the muscle that pushes the egg out of the uterus.
