• Glucose

• Water

Which process is sometimes referred to as the exchange of gases within the body?

• Internal respiration

• External respiration

• Pulmonary ventilation

• Diffusion

Why do the cardiovascular and respiratory systems increase their work rates during exercise?

• To meet the increased oxygen demand of muscles

• To decrease body temperature

• To slow down metabolism

• To reduce energy consumption

What is the main waste product removed by the respiratory system during exercise?

• Carbon dioxide

• Lactic acid

• Glucose

• Oxygen

Which of the following best summarizes the changes in the cardiovascular and respiratory systems during exercise?

• Both systems increase their work rates to meet the increased oxygen demand

• Both systems slow down to conserve energy

• Only the cardiovascular system is affected

• Only the respiratory system is affected

What physiological process increases to meet higher oxygen demands during exercise?

• Digestion

• Ventilation

• Sweating

• Bone growth

What does the term "finite capacity" refer to in the context of exercise physiology?

• The maximum heart rate

• The maximum amount of oxygen the lungs can exchange

• The minimum energy required for exercise

• The total muscle mass

What does EPOC stand for in exercise physiology?

• Excess Post-exercise Oxygen Consumption

• Exercise Performance Oxygen Capacity

• Endurance Performance Oxygen Consumption

• Elevated Pulse Oxygen Capacity

Which of the following best describes the relationship between oxygen demand and supply at the onset of exercise?
