- - - - Arrhythmias
      - Hypertention
- - - - Soley based on decision not consequences
    - - Uphold the rights of all parties
    - - Maximise happiness
    - - Motivated by virtues and outcome is less important
    - - Focus on self interests
  - - - Responsibility of corporate or the collective
      - Examples
        
        Bio-ethics
        
        Stakeholder responsibility
        
        Sustainaility
    - - Personal Decisions - Effects indicuals
      - Examples
        
        Whistleblowing (Leaking info)
        
        Falsifying records
        
        Respecting intellectual property
- - - - Reduce speed
      - Change geometry
    - - Reynold number <2000 = laminar flow
- - - - Compact (Cortical) Bone
      - Spongy (Cancellous) Bone
    - - Osteoblasts: Form new bone
      - Osteocytes: Repair/mature bone
        
        Formed from osteoblasts trapped in bone
      - Osteoclasts: Remove bone
    - - Contain Articular Cartilages
        
        Acts as a lubricant to avoid bone on bone frication
    - - Occurs naturally from mid 40s and is not possible to stop or reverse
      - Can be slowed down with exercise
      - Equally sped up by lack of exercise
      - Difficulties of creating inplants
        
        Must be custom size
        
        Difficult to make an Articular Cartilage substitute that lasts
        
        Increase bone loss often occurs around an impact due to
        
        inflammatory responses to wear particles
        
        Wear particles
  - - - 4 Chambers
        
        Right atrium
        
        Low O2, high CO2
        
        Right ventricle
        
        Left atrium
        
        Low CO2, high O2
        
        Lecft ventricle
    - - Maintain gait
      - Support Soft Tissues
      - Produce skeletal movement
      - 'Guard' entrances and exits
      - Maintain body temp
    - - Requires 2x ATP molecules
      - Forms cross-bridges
  - - - Action potential are signals to/from the CNS
      - Refractory Period = Duration of action potential
    - - Sensory Nerves (Afferent)
      - Motor Nerves (Efferent)
      - Interneurons (Within CNS)
- - - - Uses Ionising Radiation
  - - - Scanner type (Tomographic or planar)
      - Motion
    - - Motion Prevention
        
        Difficult to do so and can cause stress which changes brain fucntion
      - Motion Compensation
        
        Excluding corrupted data
        
        Image registration (alignment of multiple scans)
        
        Common example: Event-based compensation in PET
        
        Correct scan based off know motion
    - - Decreased Image Quality
      - Increased ghosting and streaking
      - Decreased Contrast
- - - - Targeted, controlled drug delivery
      - Targeted cell killing (Often for cancer)
    - - Biomedical Imaging
      - Sensing of biomolecules
  - - - Forms protein corona
