What is the bronchopulmonary segment?

Gross anatomy Each segment has its own pulmonary arterial branch and thus, the bronchopulmonary segment is a portion of lung supplied by its own bronchus and artery. Each segment is functionally and anatomically discrete allowing a single segment to be surgically resected without affecting its neighboring segments.

What is the shape of the bronchopulmonary segment?

pyramidal
Each bronchopulmonary segment is pyramidal in shape with its apex pointing toward the center of the lung and its base toward the pleural surface (Box 1).

How are bronchopulmonary segments named?

In general, each lung has 10 segments: the upper lobes contain 3 segments, the middle lobe / lingula 2 and the lower lobes 5. Bilaterally, the upper lobes have apical, posterior and anterior segments and the lower lobes superior (apical) and 4 basal segments (anterior, medial, posterior and lateral).

Where is the bronchopulmonary located?

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.

How do you remember bronchopulmonary segments?

Mnemonics to remember the bronchopulmonary segments are: A PALM Seed Makes Another Little Palm (right lung) ASIA ALPS (left lung) Mnemonics ‘A PALM Seed Makes Another Little Palm’ right upper lobe A: apical segment P: posterior segment A: anterior segment middle lobe L: lateral segment…

How many bronchopulmonary segments are there?

There are 10 bronchopulmonary segments in the right lung (3 in superior lobe, 2 in middle lobe, 5 in inferior lobe) and 9 segments on the left (4 in upper lobe, 5 in lower lobe).

What are the features of bronchopulmonary segment?

A bronchopulmonary segment is a portion of lung supplied by a specific segmental bronchus and its vessels. These arteries branch from the pulmonary and bronchial arteries, and run together through the center of the segment. Veins and lymphatic vessels drain along the edges of the segment.

How many bronchopulmonary segments are there in lungs?

Why are bronchopulmonary segments important?

The bronchopulmonary segments are the largest functional divisions of the anatomical lobes; each receiving their own air and blood supply. This article will discuss the development and anatomy of the bronchopulmonary segments. It will also review the anatomy of the lungs, and discuss the function of the organs as well.

What is the clinical significance of bronchopulmonary segment?

Bronchopulmonary segments limit the spread of some diseases within the lungs, because infections do not readily cross the connective tissue partitions between them.

How many segments are in each lung?

There are ten segments in the right lung (upper lobe, three; middle lobe, two; lower lobe, five) and eight segments in the left lung (upper lobe, four; lower lobe, four).

Which bronchopulmonary segment is more prone to infection and why?

The apical segmental bronchus is the most superior bronchus of the posterior aspect of the bronchial tree; hence, this segment is particularly prone to aspiration of fluid when a patient lies supine.
