Number of Lobes in Lungs
How many lobes are there in lungs?
As Thomas W. Shields describes on his book “General Thoracic Surgery”, the right lung ‘â€œ which is larger than the left lung ‘â€œ contains 3 lobes: upper, middle and lower. The left lung contains only 2 lobes: upper and lower. In addition to these 5 lobes, 3 accessory lobes may occur due to accessory fissures in the left lung: posterior, inferior and middle.
