What controls the circulation of blood and lymph through the body?

  1. Circulatory system

  2. Respiratory system

  3. Digestive system

  4. Muscular system

The correct answer is: Circulatory system

The circulatory system is responsible for the circulation of blood and lymph through the body. The respiratory system is involved in exchanging gases, such as oxygen and carbon dioxide, but it does not control the circulation of blood and lymph. The digestive system is responsible for breaking down food and absorbing nutrients, but it does not control the circulation of blood and lymph. The muscular system plays a role in moving blood and lymph throughout the body, but it does not have overall control. The circulatory system, specifically the heart, is responsible for pumping blood and lymph throughout the body, making it the correct answer.
