Practice Exam: Paper One
Which are the four types of bones? - ANS-long, short, irregular, flat
An athlete's broken leg is immobilized in a cast. Which muscle characteristic causes difficulty in
walking after the prolonged inactivity? - ANS-atrophy
What is the muscle labelled X in the diagram? - ANS-abdominus rectus
What is vital capacity? - ANS-total lung capacity minus residual volume
Which component of blood is greatest by volume? - ANS-plasma
How does an increased erythrocyte level benefit an athlete? - ANS-by increasing the oxygen
carrying capacity of the blood
What type of blood is pumped by each of the blood vessels listed? - ANS-vena cava:
deoxygenated
pulmonary artery: deoxygenated
pulmonary vein: oxygenated
aorta: oxygenated
How does the heart meet the demand for oxygenated blood during physical activity? -
ANS-increasing cardiac output, increasing stroke volume, increasing heart rate
What does diastolic blood pressure measure? - ANS-the force exerted by blood on arterial walls
during ventricular relaxation
Which molecule is represented by the diagram below? - ANS-glucose
What is the chemical composition of a protein molecule? - ANS-carbon, hydrogen, oxygen and
nitrogen
What is the correct order (greatest to least) for the amount of energy contained in 100g of each
body fuel? - ANS-lipid, carbohydrate, protein
What type of process is lipolysis - ANS-aerobic catabolism
Which energy system is the most rapid to resynthesize ATP? - ANS-creatine phosphate
