The right lung is a vital component of the human respiratory system, characterized by its complex and intricate anatomy. Situated within the right hemithorax of the chest, the right lung is divided into three main lobes: the upper lobe, the middle lobe, and the lower lobe. These lobes are separated by fissures, with the oblique fissure dividing the upper and lower lobes, and the horizontal fissure separating the upper and middle lobes.

Each lobe further consists of smaller functional units called bronchopulmonary segments, which are supplied by their own bronchus and blood vessels. The right lung also houses the mainstem bronchus, which branches off from the trachea and enters the lung, branching further into smaller bronchi and bronchioles, eventually leading to alveoli where gas exchange occurs.

Blood supply to the right lung is provided by the pulmonary arteries, which carry deoxygenated blood from the heart, and oxygenated blood is returned to the heart through the pulmonary veins. The intricate anatomy of the right lung plays a crucial role in ensuring efficient oxygenation of the blood and maintaining respiratory function.
