  • AS Level PE Revision (Anatomy + Physiology)
    • Newton's Laws of Motion
      • Second Law of Motion
        • "When a force is acted upon, the rate of momentum experienced by the object is proportinal to the size of force"
          • Law of Acceleration
      • Second Law of Motion:
        • "A body continues in a state of uniform velocity unless acted upon by an external force"
          • Law of Inertia
      • Third Law of Motion:
        • "Every action has an equal and opposite reaction"
    • Types of Motion
      • Linear Motion
        • When a body moves in a straight or curved line.
          • eg). Shot Putt, Golf
      • Angular Motion
        • When a body or part of the body moves in a circle or around a particular point
          • eg). Cricket Bowl, Spinning Iceskater
      • General Motion
        • A conbination of Linear and Angular motion.
          • eg). Wheelchair Athlete, Swimming
    • Transport of O2 and CO2
      • O2
        • 97% is transported with portiens inthe Haemoglobin.
        • 3% is transported inteh blood plasma
      • CO2
        • 20% is transported when combined with water in the red blood cells (carbonic acid)
        • 23% is transported as Carba haemoglobin in the haemaglobin
        • 7% is dissolved in the blokod plasma
    • Types of Coronary Heart Disease
      • Arteriosclorosis
      • Artherosclorosis
      • Angina
      • Heart Attack
    • The Respiratory Control Centre
      • It is located in the Medulla Oblongata
      • At Rest
        • The Pulmonary Pleura attaches to the lungs to the ribs so the lungs inflate and deflate as the volume of the thoracic cavity increases and decreases
      • During Exercise
        • Chemorecpetors detect changes in acidity
        • Baroreceptors detect changes in blood pressure
        • Proprioreceptors detect movement
        • Info is sent via the Phrenic Nerve
        • Inspiratory centre recieves info
    • The Skeleton
      • Types of Bone
        • Long Bones
        • Short Bones
        • Flat Bones
        • Irregular Bones
        • Sesamoid  Bones
    • Types of Synovial Joints
      • Gliding
      • Hinge
      • Ball +Socket
      • Condyloid
      • Pivot
    • Types of Joints
      • Cartilaginous Joint
        • The joints between the vertabrae
        • It is: slightly moveable, cartilage acts as a shock absorber
      • Fibrous Joint
        • It is an immovable joint
        • eg). Cranium
        • Strong fibrous structures hold bones in place, and are good at preventing injury
      • Synovial Joint
        • Allows for a wide range of movement
        • Ligaments attach bone to bone
        • Hyaline Cartilage prevents wear and tear at the end of the bone
  • Law of Acceleration
  • Types of Motion
    • Linear Motion
      • When a body moves in a straight or curved line.
        • eg). Shot Putt, Golf
    • Angular Motion
      • When a body or part of the body moves in a circle or around a particular point
        • eg). Cricket Bowl, Spinning Iceskater
    • General Motion
      • A conbination of Linear and Angular motion.
        • eg). Wheelchair Athlete, Swimming
  • CO2
    • 20% is transported when combined with water in the red blood cells (carbonic acid)
    • 23% is transported as Carba haemoglobin in the haemaglobin
    • 7% is dissolved in the blokod plasma
