The right lung is anatomically divided into three lobes: the upper lobe, the middle lobe, and the lower lobe. This structure allows for a larger surface area for gas exchange and is essential for effective respiratory function. Each lobe is separated by fissures; the horizontal fissure separates the upper and middle lobes, while the oblique fissure separates the middle and lower lobes. Understanding this anatomical structure is significant for EMTs as it helps in assessing respiratory conditions, where knowledge of lung lobes can assist in identifying the location of potential issues such as pneumonia or other pulmonary diseases.
