potential role of human visceral pleura in pleural fluid turnover

With continuing advanced research into pleural fluid turnover, the majority of scientists hold the view that pleural fluid is derived from the microvessels in parietal pleura and drained via parietal lymphatic vessels which empty into systemic veins. The lymphatic vessels that contribute to the pulmonary lymphatic circulation originate in the subpleural connective tissue, not directly from the visceral mesothelium. Therefore, according to the current point of view, pleural effusion absorption through the visceral pleural is normally neclligible and visceral pleura,
