Mr Siphо Dlаmini, а 28-yeаr-оld prоfessional rugby player, sustains a serious abdominal injury during a match and undergoes emergency abdominal surgery. Before the injury, he had no known cardiovascular or respiratory disease and regularly participated in intensive training. Following surgery, he is admitted to the intensive care unit, where he is sedated and receives controlled invasive mechanical ventilation. The multidisciplinary team assesses his breathing while he is sitting upright. As his condition improves and he receives medical clearance, his rehabilitation progresses from sitting and walking to supervised exercise on a stationary bicycle. The physiotherapist reduces the workload and encourages slower, deeper breaths. Later in his rehabilitation, he tolerates progressively higher workloads as he prepares to return to professional sport. The team considers Mr Dlamini's ventilation-perfusion relationships during his upright (sitting) assessments and exercise. Explain how increased pulmonary perfusion and improved regional V/Q matching during exercise support oxygen uptake and carbon dioxide removal. [BLANK-1]
