Structure of the Lungs
The lungs are conical-shaped with an apex, three surfaces, three borders, and a base.
- Apex: It is a blunt end at the top (superior end), located above the level of the first rib.
- Three surfaces: The coastal surface is towards the sternum and ribs, the medial surface is towards the sternum and the vertebrae, and the diaphragmatic surface is towards the diaphragm.
- Three borders: The anterior border is thin and sharp, and in the left lungs consists of the cardiac notch, the posterior border is smooth and round, and the inferior border is sharp separating the base of the lungs from the surface of the diaphragm.
- Base: It is the bottom (inferior end) of the lungs that is placed above the diaphragm.
Anatomy of the Human Lung
The anatomy of the human lung shows a complex network of airways and alveoli which is crucial for respiratory function and gas exchange. The human lung anatomy shows paired organs that are located in the thoracic cavity of the upper body. The lungs are the primary organ of the respiratory system.
It is the organ where the exchange of gases i.e. oxygen in and carbon dioxide out takes place. Lungs are also found in other vertebrates except fishes as they have gills to perform the exchange of gases. In this article, we will study in detail about anatomy of human lungs and its diagram.
