The right lung is one of the two lungs in the human body, located in the thoracic cavity. It is larger and broader than the left lung, consisting of three lobes: the upper, middle, and lower lobes. The right lung is responsible for taking in oxygen and expelling carbon dioxide, playing a crucial role in the respiratory system. The right lung is separated from the left lung by the mediastinum, which contains the heart and other vital structures. It is also connected to the trachea, which branches into the bronchi, allowing air to flow in and out. Proper functioning of the right lung is essential for overall health and well-being.
