Lungs – Collage Anatomy
This image takes you from the person (1) to the alveolus (8,9)- a continuum of structure – each element an individual unit, which in concert work for the harmony of health. Image 2 is a post mortem specimen showing trachea and proximal bronchi entering the lung. The chest X-ray showing the lungs in black within the thoracic cavity (3) is followed by a diagram of the same structure(4), secondary lobule(5), acinus (6), connective support tissues (7), and then the alveoli (8.9).

This artistic rendition of the heart and lungs uses the shape of fruit and vegetables to create an image of the chest. The lungs are made of grapes, the pulmonary arteries are made of carrots, the ribs are made of banana peel and the heat is made of a red pepper.

CELLS OF THE ALVEOLI
There are two types of cells lining the alveoli: Type I alveolar cells (pneumocytes) are squamous cells. They enable gas exchange. Type 2 alveolar cells ,are cuboidal in shape and they secrete surfactant.

Alveolus Cells and Capillaries of the Lung
“Alveolus Cells and Capillaries of the Lung” shows an alveolus with single cell lining and associated arteriole, capillary and venous circulation. The cool fresh air flows into the alveolus, and oxygen flows into the blue blooded arteriole converting into a red blooded venule. A breeze of carbon dioxide flows through the single celled alveolus and into the airways for expiration

The Acinus,
The Duct, and the Artery
The pulmonary arteriole (pa) accompanies the lobular bronchiole (lb). The arteriole transports deoxygenated blood and the bronchiole carries oxygen from the trachea to the alveoli.
They part ways at the alveoli

Multiple Acini

The Acinus,
The Duct, and the Artery
The pulmonary arteriole accompanies the airway as it carries oxygen from the trachea to the alveoli. They part ways at the alveoli where the pulmonary venule then takes the oxygenated blood from capillary network around the alveoli back to the left atrium.
The intimate relationship of the airways and the pulmonary artery and their close approximation in size, is helpful in radiology, firstly to identify theese structures and secondly to define disease such as heart failure and bronchiectasis.
The acinus as shown in this image is defined as a unit of lung consisting of a single first order respiratory bronchiole that subtending a cluster of alveoli reminiscent of a bunch of grapes or berries (acinus in Latin means berry) . The lobular bronchiole (lb) branches into the terminal bronchiole (tb), which then branches into the first order respiratory bronchiole (rb). Subsequent branching after the respiratory bronchiole, includes in order, the alveolar duct (ad), alveolar sac (as), and then finally the berry like alveoli.

The Ductal System of the Acinus
The diagram shows the ductal system of the acinus, starting with the tick walled terminal bronchiole (tb) that is the last duct of the conducting system of the airways. The respiratory bronchiole (rb) enters the secondary lobule and is the first duct to have diffusion capability. There can be 3 orders of rb’s, and they branch into alveolar ducts, which branch in turn to alveolar sacs until they reach the alveoli, which is the final destination.

The Secondary Lobule

This image is a panoramic view of the lung showing in this case almost rectangular secondary lobules surrounded by interlobular septa (cream borders) The distal bronchioles (teal) and pulmonary arteriole (royal blue are shown in the centre of a lobule in the right lower corner. The branches of these two structures are shown in the secondary lobule with the acinar airways shown in teal and the presumed course artistically inferred in royal blue. Within the interlobular septa (light pink) remnants of the pulmonary venules (red – inferred) and lymphatics (yellow inferred) course going in the opposite direction to the arteriole and the airways.

SEGMENTS OF THE LUNGS
The secondary lobules, connect, and unite, linked through the airways, blood vessels, lymphatics and nerves, to form segments in the lungs
There are ten bronchopulmonary segments in the right lung: three in the upper lobe, two in the middle lobe, and five in the lower lobe. Some of the segments may fuse in the left lung to form usually eight to nine segments (four to five in the upper lobe and four to five in the lower lobe.

LOBES OF THE LUNGS

This collage reflects the range of the respiratory system from the macroscopic and anatomic to the microscopic – a continuum of structure. Image 2 is a post-mortem specimen taken from the front and slightly above. It shows the trachea and bronchi supplying the two lungs above, with the aortic arch and cardiac structures in the middle and below. Note how pink the lungs are in this specimen from an unfortunate baby with congenital heart disease. Image 3, the chest X-ray, shows the lucent lungs within the thoracic cavity while image 4 is a diagram of the trilobed right lung and the bilobed left lung. Two respiratory units of the lung are shown in the next image each called a pulmonary lobule (5). The lobule consists of a central bronchiole (light blue) and pulmonary arteriole (dark blue), surrounded by the air filled acinus (teal) with its peripheral venules. (red) The acinus is magnified in the next image (6), showing first the tubular terminal bronchiole branching into the respiratory bronchioles, alveolar sacs, and finally the grape like alveoli. The organization of the connective tissues of the lung is shown in image 7. Finally we get down to the grapes or alveoli of the lung with surrounding vessels (8), and a single alveolus is seen in 9. It seems a long way for the air to travel but the system can deliver the air to and from the outside in a single breath, and exchange the gases at the capillary level even more rapidly. It is a remarkable system.
