What two systems constitute the circulatory system?

The circulatory system is predominantly made up of two main components: the cardiovascular system and the lymphatic system. The cardiovascular system consists of the heart, blood vessels, and blood, playing a crucial role in transporting oxygen, nutrients, hormones, and waste products throughout the body. It is essential for maintaining internal homeostasis as well as supporting metabolic processes.

On the other hand, the lymphatic system complements the cardiovascular system by managing the body’s fluid levels, absorbing digestive tract fats, and supporting the immune system. It includes lymph vessels, lymph nodes, and lymph fluid, facilitating the return of excess interstitial fluid to the bloodstream and helping to filter pathogens from the body.

Together, these two systems work in concert to ensure the effective circulation of blood and lymph, essential for overall health and homeostasis. This interconnectedness is what makes the combination of the cardiovascular system and lymphatic system the correct answer to the question regarding the components of the circulatory system.
