Summary Introduction
Introduction:
Lungs are respiratory organs located in the thoracic cavity. Lungs consist of lobes. Right lung consists of three lobes, whereas left lung consists of two lobes. Lobes are further divided into bronchopulmonary segments. The right and left lobes of the lungs attach to the right and left bronchus respectively. The bronchus is further divided into many bronchioles that consist of alveoli. A bunch of alveoli present on a single respiratory bronchiole is termed as a lobule.
