Blood and Its Role in Sports

What is the primary function of red blood cells?

• To clot blood

• To fight infection

• To transport oxygen

• To regulate temperature

Which blood component helps seal a wound after a sports injury?

• Plasma

• Red blood cells

• White blood cells

• Platelets

Why are white blood cells important for athletes?

• They increase oxygen delivery

• They remove lactic acid

• They fight disease and infection

• They build muscle tissue

What role does plasma play in blood circulation?

• It increases blood pressure

• It transports other blood components

• It prevents infection

• It breaks down glucose

Which of the following sporting scenarios best illustrates the role of red blood cells?

• A rugby player with a head wound

• A runner needing oxygen during a marathon

• A boxer with a swollen eye

• A footballer recovering from flu

If an athlete has a low platelet count, what is the likely risk?

• Reduced oxygen uptake

• Slower heart rate

• Poor wound healing and excessive bleeding

• Increased risk of muscle fatigue

Which scenario best shows the role of white blood cells?

• A long-distance swimmer using oxygen efficiently

• A tennis player recovering from illness and returning to training

• A cyclist using carbohydrates for energy

• A gymnast improving flexibility

Why is plasma important in transporting red and white blood cells?

• It removes carbon dioxide

• It keeps blood flowing around the body

• It increases bone density

• It improves flexibility

During a football match, a player cuts their knee. Which blood component acts quickly to prevent blood loss?

• Plasma

• White blood cells

• Platelets

• Red blood cells

A marathon runner benefits from a high red blood cell count because:

• It helps prevent injury

• It improves oxygen delivery to working muscles

• It reduces body temperature

• It increases muscle size
