Which two body systems are involved when lungs supply oxygen carried by blood to the body's cells?

• A. Integumentary and Muscular
• B. Respiratory and Circulatory
• C. Lymphatic and Immune
• D. Nervous and Endocrine

Answer: (B)

Lungs are essential components of the respiratory system, responsible for facilitating gas exchange—specifically, taking in oxygen and expelling carbon dioxide. When the lungs supply oxygen, this oxygen enters the bloodstream, which is the primary function of the circulatory system. The circulatory system comprises the heart, blood vessels, and blood. It transports the oxygen that has been absorbed into the bloodstream from the lungs and delivers it to the body's cells, where it is utilized for various metabolic processes. This interaction between the respiratory system, which supplies oxygen, and the circulatory system, which carries it, is fundamental to maintaining cellular function and overall homeostasis in the body. Thus, these two systems work together seamlessly to ensure that all body cells receive the oxygen they need to produce energy efficiently.
