Q: How does exercise affect the circulatory system?
Solution:
Exercise increases blood flow and heart rate to meet the higher oxygen demands of the body during physical activity.
Steps: 5
Show Steps
Step 1: When you start exercising, your muscles need more oxygen to work harder.
Step 2: To supply this oxygen, your heart beats faster to pump more blood.
Step 3: The blood carries oxygen and nutrients to your muscles and removes waste products.
Step 4: As you continue to exercise, your blood vessels widen to allow more blood flow.
Step 5: This increased blood flow helps improve your overall heart health and fitness.
