Which of the following statements about the skeletal system is false?

• The humerus is part of the appendicular skeleton.

• Kicking a ball requires flexion at the hip joint.

• Long bones have articular surfaces for smooth joint action.

• The pelvis is inferior to the femur.

Which of the following statements about the muscular system is true?

• Slow twitch muscle fibres are white in colour and mostly suited to sprinting.

• Standing up from a squat position

Which of the following statements about balance and stability is false?

• A. A lower centre of gravity increases stability.

• B. A larger base of support can help someone maintain balance.

• C. The body is most stable when the line of gravity is above the base of support.

• D. The centre of gravity is always at a point just above the naval region in the abdomen towards the posterior side.

Which of the following statements about fluid mechanics is true?

• By increasing the frontal surface area in sport, drag is increased allowing for faster movement.

• Spherical balls are the most aerodynamic shape as air can flow around the ball with minimal turbulence or drag.

• The Magnus effect states that a spinning ball will swing towards that side of the ball that is spinning in the same direction as the ball.

Which of the following statements about the respiratory system is true?

• Expiration involves contraction of the diaphragm to draw air into the lungs.

• The alveoli have semipermeable membranes allowing for external respiration through gaseous exchange.

• Expired air has no oxygen left after the body has used it all up.

• The right lobe of the lung has two lobes to accommodate the space of the heart.

Which of the following statements about the circulatory system is false?

• The atrium is superior to the ventricles.

• The pulmonary vein carries deoxygenated blood to the lungs.

• Capillaries are the only blood vessel with semipermeable membranes.

• The systemic circulatory system is pumped from the left-hand side of the heart to the brain and body.

8 Which of the following statements about the digestive system is true?

• The digestive system controls movement and balance.

• The digestive system produces hormones for growth.

Which of the following statements about the endocrine system is false?

• Hormones are always released very close to the target receptor cells so they can signal a response.

• The adrenal gland near the kidneys produces hormones that signal the flight or fight response.
