Questions & Step-by-Step Solutions
How does exercise affect the circulatory system?
Steps
Concepts
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.
Circulatory System Response to Exercise
– Exercise leads to increased heart rate and blood flow to supply more oxygen to muscles.
Oxygen Demand
– During physical activity, the body's demand for oxygen rises, prompting physiological changes.
