Into which system does lymph flow?

1. Digestive system

2. Nervous system

3. Respiratory system

4. Circulatory system

The correct answer is: Circulatory system

Lymph flows into the circulatory system, which is responsible for the transport of blood, nutrients, gases, and waste throughout the body. The lymphatic system is a crucial component of the circulatory system, serving to maintain fluid balance by collecting excess tissue fluid and filtering it through lymph nodes before returning it to the bloodstream. This function helps in immune response, as lymph nodes contain white blood cells that play a role in defending the body against pathogens. The digestive system does involve the movement and processing of nutrients, but it is not directly involved in the flow of lymph. The nervous system focuses on the transmission of signals for bodily functions and coordination, while the respiratory system is primarily concerned with the exchange of gases. Thus, the circulatory system is the correct answer as it provides the pathway for lymphatic fluid to return to the bloodstream, ensuring the integration of lymphatic drainage with circulatory processes.
