Physiology of lung water. There is a physiological net outward fluid filtration from microvessels to the interstitium governed by the Starling’s law, which is strictly controlled by the lymphatic drainage system (P alv alveolar pressure, P H hydrostatic pressure, P onc oncotic pressure, K filtration coefficient of the alveolocapillary barrier, Kσ reflection coefficient of the alveolocapillary barrier)
