Lung Anatomy &Development

Lungs are the most important organs of the respiratory system, and they are separated into lobes. The right lung, which has three lobes, is slightly larger than the left lung, which only has two. The mediastinum is the space between the lungs. The heart, trachea, oesophagus, and several lymph nodes are all located in this location. In humans, the lung develops as a ventral outpouching of the primitive foregut into the surrounding ventral mesenchyme at 4-6 weeks of gestation. This structure is known as the laryngotracheal groove, and it is the precursor to the larynx and the trachea.
