A cosmetologist is explaining the benefits of massage to a client. Which body system is most directly affected by massage techniques that aim to improve blood flow and oxygen delivery to tissues?
- ANervous system
- BMuscular system
- CSkeletal system
- DCirculatory system
Show answer & explanationAnswer & explanation
Correct answer: D. Circulatory system
Massage techniques that improve blood flow and oxygen delivery directly target the circulatory system. This system is responsible for transporting blood, which carries oxygen and nutrients, throughout the body.
Why the other options are wrong
- A. The nervous system controls sensation and muscle contraction, but improved blood flow is a direct function of the circulatory system.
- B. While muscles are often the target of massage, the *effect* of improved blood flow and oxygen delivery is a function of the circulatory system.
- C. The skeletal system provides structure and support and is not directly involved in blood flow or oxygen transport.
Circulatory System Function
The circulatory system, composed of the heart, blood vessels, and blood, is responsible for transporting substances throughout the body.
- Transports oxygen from lungs to tissues.
- Delivers nutrients from the digestive system to cells.
- Removes metabolic waste products.
- Distributes hormones and regulates body temperature.
Memory trick: Circulatory system is the 'body's highway' for blood.
