Anatomy Of Lungs
By-DipeshGamare
Introduction and Location
 The lungs, which is the organ for respiration is a paired cone shaped organs lying in the thoracic cavity separated from
each other by the heart and other structures in the mediastinum.
 Each lung has a base resting on the diaphragm and an apex extending superiorly to a point approximately 2.5 cm
superior to the clavicle
 It also has a medial surface and with three borders- anterior, posterior and inferior.
 The broad coastal surface of the lungs is pressed against the rib cage, while the smaller mediastinal surface faces
medially.
 The lungs receives the bronchus, blood vessels, lymphatic vessels and nerves through a slit in the mediastinal surface
called the helium, and the structures entering the helium constitutes the lungs root
 The right lung is larger and weighs more than the left lung.
 Since the heart tilts to the left, the left lung is smaller than the right and has an indentation called the cardiac impression
to accommodate the heart.
 This indentation shapes the inferior and anterior parts of the superior lobe into a thin tongue-like process called the
lingual.

Pleura
Each lung is invested by and enclosed in a serous pleural sac that consists of two
continuous membranes.
The visceral or pulmonary pleura invest the lungs,
The parietal pleura line the pulmonary cavities and adhere to the thoracic wall,
mediastinum and diaphragm.
The parietal pleura consist of four parts:
coastal pleura which lines the internal surface of the thoracic wall, mediastinal pleura
which lines the lateral aspect of the mediastinum, diaphragmatic pleura which lines
the superior surface of the diaphragm on each side of the mediastinum, cervical pleura
extends through the superior thoracic aperture into the root of the neck, forming a cup-
shaped dome over the apex of the lung.
 Pleural Cavity
 The pleural cavity is the potential space between the visceral and parietal layers of the pleural and it contains a
capillary layer of serous pleural fluid which lubricates the pleural surfaces and allows the layers to slide smoothly
over each other during respiration.
 Surface tension created by the pleural cavity provides the cohesion that keeps the lung surface in contact with the
thoracic wall
Lobes and Fissures of the Lungs
Each lung is divided into lobes by fissures.
Both lungs have oblique fissure and the right is further divided by a transverse
fissure. The oblique fissure in the left lung separates the superior and the inferior
lobe. The oblique and horizontal fissure divides the lungs into superior, middle
and inferior lobes. Thus the right lung has three lobes while the left has two.
Each lobe is supplied by a lobar bronchus. The lobes are subdivided by
bronchopulmonary segments which are supplied by the segmental bronchi.
Bronchial Tree
 All the respiratory passages from the trachea to the respiratory bronchioles are called the tracheobronchial tree.
 The trachea divides at the sternal angle into right and left primary bronchus which goes into the right and left
lungs.
 Each bronchus enters the lung at a notch called the hilum.
 Blood vessels and nerves also connect with the lungs here and together with the bronchus forms a region called
the root of the lungs.
 The right main bronchus is larger in diameter and more vertical making it directly in line with the trachea than the
left main bronchus. Thus swallowed objects that accidentally enter the lower respiratory tract are most likely to
become lodged in the right main bronchus.
 The main bronchi divide into lobar or secondary bronchi within each lung. Two lobar bronchi exist in the left lung,
and three exist in the right lung. The lobar bronchi, in turn give rise to segmental or tertiary bronchi. The tertiary
bronchi supply the bronchopulmonary segments
Bronchopulmonary Segment
 Functionally, the lung is divided into a series of bronchopulmonary segments. The bronchopulmonary
segments are the largest subdivision of a lobe.
 They are separated from adjacent segments by connective tissue septa and are also surgically resectable.
 They are 10 bronchopulmonary segments in the left lung and 8-10 in the left lung.
 The bronchi further divides, finally giving rise to the bronchioles which are less than 1mm in diameter.
 Each bronchioles divides into 50 to 80 terminal bronchioles, the final branches of respiratory
bronchioles.
 The functional unit of the lungs which is the acinus includes the respiratory bronchioles, alveolar ducts,
and sacs and the alveolar.
 Approximately 16 generations of branching occur from the trachea to the terminal bronchioles. As the
air passageways of the lungs become smaller, the structure of their walls changes.
