Why is exercise important to healing?

• A. Decreases blood flow to tissue
• B. Stimulates circulation and increases oxygen delivery to tissues
• C. Increases scar tissue formation
• D. Delays wound healing

Answer: (B)

Regular movement and controlled exercise help healing because they boost circulation, bringing more oxygen and nutrients to the damaged tissue while helping remove waste products. Oxygen is essential for cellular energy and for building new tissue, so better delivery supports faster and more effective repair. Exercise also aids the immune response at the wound site and helps reduce edema through the muscle pump effect, which can lessen swelling and stiffness and promote tissue remodeling. That’s why the choice describing stimulation of circulation and increased oxygen delivery to tissues is the best explanation. Decreasing blood flow would hinder healing, increasing scar tissue formation isn’t an automatic or beneficial result of exercise, and delaying wound healing is simply the opposite of what appropriate exercise aims to achieve.
