Inside the lungs, the bronchus forms lobar bronchus for the supply in the lobes. It has its branches to the left and right bronchus, starting from the trachea.

Bronchial Tree: The bunch of passages supplying air to the alveoli is called the bronchial tree.

The inferior border separates the base of mediastinal and costal surfaces. The posterior junction of mediastinal and costal surfaces makes the posterior border. The convergence is present in the mediastinal and costal surfaces from the anterior border.

Borders (three): The lungs' anterior, inferior, and posterior edges are called the borders.

The coastal surface separates the ribs and intercostal muscles. The diaphragmatic surface makes the base of the lungs.

The hilum of the lung is there on the mediastinal surface. These surfaces correspond to one particular thoracic area. Surfaces (three): Lung has three surfaces, namely, costal, mediastinal, and diaphragmatic.An oblique fissure separates the lobes of the left lung. The lobes of the right lung are divided by fissures, namely oblique and horizontal fissures. The right lung has three lobes (superior, middle, and inferior), while the left has two (superior and inferior). Lobes (two or three): The fissures on the lungs separate them into lobes.

Base: The base is the inferior surface of the lung resting on the diaphragm.It is there on the floor of the neck, above the level of the first rib. Apex: There is a blunt end at the superior part of the lung, which is called the Apex.In this part, it will give you a detailed introduction of lung structure. How does the lung look like, or what is the structure of lung.
