Figure 2From: An integrated physiology model to study regional lung damage effects and the physiologic responseSheep lung model. The sheep lung structure is modeled as an asymmetric bifurcating tree based on morphological measurements. The right lung contains 4 lobes, while the left lung contains 2 lobes. The pulmonary arteries track the airways to the capillary bed, where the blood is oxygenated and returns to the systemic circulation via pulmonary veins.Back to article page
