How many lobes does the right lung have?

The right lung is composed of three lobes: the upper lobe, middle lobe, and lower lobe. This anatomical structure is significant as it allows for efficient airflow and gas exchange within the pulmonary system. The presence of three lobes is related to the overall size and shape of the right lung, which is larger and wider than the left lung to accommodate the space taken up by the heart on the left side of the thoracic cavity. Understanding the lobular arrangement is essential for grasping concepts related to respiratory health and the distribution of diseases like pulmonary infections or tumors within the lungs.
