Final answer:
The oblique fissure of the right lung separates the superior and middle lobes from the inferior lobe. It runs obliquely from the posterior to the anterior surface of the lung. This fissure creates distinct lobes and allows for better lung expansion.
Step-by-step explanation:
The oblique fissure of the right lung is a division of the lung that separates the superior and middle lobes from the inferior lobe. It runs obliquely from the posterior to the anterior surface of the lung, curving around the inferior border. The oblique fissure is responsible for creating the distinct lobes of the right lung and allows for greater expansion and ventilation.
