2023年5月1日 · The lungs are a pair of primary organs of respiration, present in the thoracic cavity beside the mediastinum. They are covered by a thin double-layered serous membrane called the pleura. The respiratory system consists of two components, the conducting portion, and the respiratory portion.
Lungs | Respiratory System - Histology Guide
The lung consists of airways and structures for gas exchange. The trachea divides into a primary bronchus for each lung. The smaller intrapulmonary airways are devoid of cartilage and glands in their walls. Epithelium changes from pseudostratified columnar to simple, ciliated columnar epithelium as they decrease in diameter.

The events of human lung growth are divided into five continuous stages, based on anatomic and histological characteristics. These are the embryonic, pseudoglandular, canalicular, saccular and alveolar stages (Table 1) (Figures 1 and 2). Airway and vascular development are closely related.

2024年1月24日 · Histological appearance of normal lung tissue and its components. The respiratory system consists of several organs working together to facilitate the exchange of oxygen and carbon dioxide between the air and the bloodstream, supporting cellular respiration. The respiratory tract is divided into two sections; the upper and l ower respiratory tract.

2023年11月21日 · The human lungs are a pair of spongy organs within the thoracic cavity that facilitate gaseous exchange. They are a part of the respiratory system, which also includes the nose, nasal sinuses, mouth, pharynx, larynx, and trachea. At the level of the lungs, much-needed oxygen is absorbed into the blood, while waste gases are excreted and exhaled.
Espousing the precept that an understanding of normal anatomy is essential for the recognition and appreciation of abnormal structure, this chapter on practical lung anatomy and histology provides the reader with a base line for the evaluation of macroscopic, histologic, and ultrastructural changes imparted by disease.
