- 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
- "When a force is acted upon, the rate of momentum experienced by the object is proportinal to the size of force"
- Second Law of Motion:
- "A body continues in a state of uniform velocity unless acted upon by an external force"
- Law of Inertia
- "A body continues in a state of uniform velocity unless acted upon by an external force"
- Third Law of Motion:
- "Every action has an equal and opposite reaction"
- Second Law of Motion
- Types of Motion
- Linear Motion
- When a body moves in a straight or curved line.
- eg). Shot Putt, Golf
- When a body moves in a straight or curved line.
- Angular Motion
- When a body or part of the body moves in a circle or around a particular point
- eg). Cricket Bowl, Spinning Iceskater
- When a body or part of the body moves in a circle or around a particular point
- General Motion
- A conbination of Linear and Angular motion.
- eg). Wheelchair Athlete, Swimming
- A conbination of Linear and Angular motion.
- Linear Motion
- 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
- O2
- 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 Bone
- 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
- Cartilaginous Joint
- Newton's Laws of Motion
- Law of Acceleration
