Question 1: Describe two short-term effects that physical activity has on your cardiovascular system immediately after exercise.

Answer: An increase in heart rate and faster breathing to supply more oxygen to the muscles.

Question 2: Explain how regular exercise can lead to long-term improvements in muscular strength and endurance.

Answer: Consistent exercise causes muscles to adapt by increasing muscle fiber size and efficiency, resulting in greater strength and endurance over time.

Question 3: Identify two short-term effects of physical activity on your respiratory system.

Answer: Increased breathing rate and deeper breaths to meet oxygen demands.

Question 4: Describe the long-term effect of regular aerobic exercise on lung capacity.

Answer: Enhanced lung capacity, allowing more oxygen to be taken in and used during physical activity.

Question 5: Explain how consistent exercise can improve your skeletal system in the long term.

Answer: It stimulates bone growth and increases bone density, reducing the risk of osteoporosis.

Question 6: Describe a short-term effect of vigorous exercise on your body’s temperature regulation.

Answer: Your body warms up, leading to increased sweating to cool down and regulate temperature.

Question 7: Identify two long-term effects of regular physical activity on your nervous system.

Answer: Improved coordination and quicker response times due to enhanced neural pathways.

Question 8: Sketch a diagram of the human muscular system, labeling at least five major muscle groups.

Answer: A clear sketch showing major muscle groups such as the biceps, quadriceps, hamstrings, pectorals, and abdominals, with labels for each.

Question 9: Draw a simple diagram of the human cardiovascular system, indicating the heart, arteries, and veins.

Answer: A rough diagram with a central heart, with arteries flowing away from it and veins returning to it, properly labeled.

Question 10: Explain how long-term physical activity can help prevent osteoporosis.

Answer: Weight-bearing exercises stimulate bone formation and increase bone density, reducing osteoporosis risk.

Question 11: Describe two effects that regular physical activity can have on your mental health and motivation.

Answer: It can reduce stress and anxiety, and boost confidence and motivation through improved physical fitness.
