What do we call the system that enables the exchange of oxygen and carbon dioxide?

The system responsible for the exchange of oxygen and carbon dioxide is the respiratory system. This system includes structures such as the lungs, trachea, and diaphragm, which facilitate the process of breathing. During inhalation, oxygen from the air is brought into the lungs and transferred to the bloodstream, where it is then delivered to the body's tissues. Simultaneously, carbon dioxide—a waste product of metabolism—is transported from the tissues back to the lungs to be exhaled.

The respiratory system is critical for maintaining the body’s gas exchange, ensuring that oxygen is supplied to the bloodstream while carbon dioxide is removed, which is essential for cellular respiration and overall metabolic function. This foundational process has direct implications for health and homeostasis, making the respiratory system vital for life.
