Why lungs are divided into lobes?
The fissures are formed in early prenatal development by invaginations of the visceral pleura that divide the lobar bronchi, and section the lungs into lobes that helps in their expansion. The right lung is divided into three lobes by a horizontal fissure, and an oblique fissure.
Does the left lung have 2 lobes?
The left lung consists of two lobes: the left upper lobe (LUL) and the left lower lobe (LLL). The right lobe is divided by an oblique and horizontal fissure, where the horizontal fissure divides the upper and middle lobe, and the oblique fissure divides the middle and lower lobes.
Why is left lung smaller than right?
The left lung is a little smaller than the right lung because it shares space in the left side of the chest with the heart.
How many lobes are in both lungs combined?
The lung consists of five lobes. The left lung has a superior and inferior lobe, while the right lung has superior, middle, and inferior lobes. Thin walls of tissue called fissures separate the different lobes.
