Chapter 1
State a bone in the lower body
Femur, Tibia, Fibula, Tarsals, Metatarsals, Talus, Phalanges, Patella
Which component in the pathway of air is responsible for gas exchange?
Which artery pumps blood to the body?
Aorta
Explain RICE
Rest, Ice, Compression, Elevate
Which lever class is used when kicking a ball.
Class 2
State all 4 function of bones
Shape and Support, Red Blood Cell Production, Protection. Muscles Attach Onto For Movement.
How to calculate minute ventilation.
tidal volume x breaths per minute
State the 4 components of blood.
Plasma, Red blood cells, White blood cells, Platelets.
State 3 short term effects of exercise.
Give 2 things a cyclist can do to reduce air resistance.
Aerodynamic bike, Aerodynamic helmet, Skin tight clothing...
State all components in the synovial joint.
Synovial Membrane, Synovial Fluid, Articulate Cartilage, Joint Capsule, Bone.
Describe the pathway of air.
Mouth/Nose --> Trachea --> Bronchus --> Bronchioles --> Alveoli
Define haemoglobin
A dark red chemical substance that is responsible to carry oxygen.
State the chemical equation for anaerobic respiration.
C6H12O6 --> H2O + CO2 + Energy + Lactic Acid
State the 3 laws of Newton
Law of inertia, Law of motion, Law of acceleration
What type of movement does the contraction of the gastrocnemius produce?
Plantarflextion
State 4 mechanics of breathing during inhalation.
Thorax Increases In Volume, Thorax Decreases In Pressure, Ribcage Moves Up and Out, Intercostal Muscles Relax, Diaphragm Contacts and Flatten.
State the difference of the left ventricle and right ventricle, and why
thicker in size, higher in pressure.
What's the definition of EPOC?
The increase of oxygen intake after strenuous exercise.
A cyclist accelerates at 2m/s2 with a mass of 70kg, calculate the force they generate, and how may air resistance affect this.
F=140N; air resistance slows the cyclist down.
State 5 differences of fast twitch and slow twitch muscle fibres.
contract slowly, contract quickly
produce little force, produce large force
higher fatigue tolerance, lower fatigue tolerance
good for endurance, good for strength and power
red in colour, white in colour
Vital capacity and residual volume correlate to the amount of air in your lungs, which therefore links to the knowledge of total lung capacity.
Give me the pathway of blood.
Vena cava --> right atrium --> right ventricle --> pulmonary artery --> lungs --> pulmonary vein --> left atrium --> left ventricle --> aorta --> body.
State the lactic acid equation.
Lactic acid + oxygen --> water + carbon dioxide + glucose.
Knowing that the farther away the effort is, the easier it is to fight the resistance. (E.g.)
