Alveoli | Lung | Respiratory System - Histology Guide
Alveoli (white background) Macrophage (tan) - darker because of ingested dust and carbon from the air and complexed iron (hemosiderin) from leaked red blood cells. Collagen/Elastic Fibers (orange) – abundant within interalveolar septa; Type I cells contain abundant caveolae that protect against mechanical stress and facilitate membrane repair.

Alveoli (lung, SEM) | Respiratory System - Histology Guide
Alveoli are cup-shaped structures that open into alveolar sacs. The diameter of an alveolus is between 200 and 500 µm. Alveoli - extremely attenuated, simple squamous epithelium covering a fine mesh of capillaries; Alveolar Pores - adjacent alveoli are …

Respiratory: The Histology Guide - University of Leeds
Can you identify the thin type I pneumocytes, macrophages and capillaries? This diagram shows a diagram of an alveolar sac, showing how the organisation of the alveoli, and the network of blood capillaries that surround the alveoli (in red). The epithelium of …

2023年8月28日 · Alveoli represent the major sites of gas exchange. Their presence increases the surface area of the lung to maximize gas exchange, much like villi and microvilli increase the absorptive surface area of the digestive tract. For alveoli to carry out their function efficiently, they must be both a dynamic and stable system.
Alveoli 6 - Digital Histology
The components of the alveoli and the interalveolar septa are illustrated in this image. 1000x
Alveoli 2 - Digital Histology
This electron micrograph shows many of the components of the interalveolar septum illustrated in the cartoon. The attenuation of type I cell cytoplasm and the protrusion of the capillaries are most evident. Surfactant is not preserved during fixation of lung tissue, and no septal cells nor macrophages are present in this image. 4000x
Terminal Bronchiole, Respiratory Bronchiole, Alveolar Duct
The left side of the picture shows a portion of an alveoli duct with “doors only” arrangements of alveoli. “Looking backward”, the bronchiole is a terminal bronchiole because it immediately precceds a respiratory bronchiole.
Histology, Lung - StatPearls - NCBI Bookshelf
2023年5月1日 · Alveoli: The alveoli are the specialized air-sacs (outpouching) of 200 µm diameter. These are the structural and functional unit of the respiratory system. These are the primary site of exchange of oxygen and carbon dioxide. There are 300 million alveoli in the lungs, and these give approximately 140m surface area for the exchange of gases.
