The technique that releases nutrients and carbon dioxide and purifies the system is ________.

• A. Tapotement
• B. Effleurage
• C. Petrissage
• D. Friction

Answer: (A)

Tapotement involves quick, rhythmic percussion on the body—tapping, hacking, cupping, or clapping. This lively contact jolts tissues, boosting local blood flow and stimulating the lymphatic system. When circulation and lymph movement ramp up, nutrients are delivered more efficiently to cells and metabolic wastes, including carbon dioxide, are cleared away more effectively. That enhanced exchange gives a sense of purification or cleansing of the system. Other techniques have different primary effects: effleurage is gentle gliding that mainly aids venous return and relaxation; petrissage kneads and lifts tissue to release adhesions and improve local circulation; friction heats and rubs deeper layers to break down knots. But tapotement best fits the idea of a broad, stimulating effect that promotes cleansing through increased circulation and waste removal.
