State that carbon dioxide is excreted through the lungs
Answer
Carbon dioxide is excreted through the lungs in humans. This process occurs during respiration, where carbon dioxide, a waste product of cellular metabolism, is transported from the body’s tissues to the lungs. Here, carbon dioxide diffuses from the blood into the alveoli, the tiny air sacs in the lungs, and is subsequently expelled from the body during exhalation.During inhalation, oxygen enters the lungs and reaches the alveoli, where it passes into the bloodstream. Conversely, carbon dioxide moves from the blood into the alveoli, allowing it to be exhaled. This exchange is crucial for maintaining proper gas levels in the body and is facilitated by the respiratory system’s structure and function
