What Are the Key Histological Structures Involved in Breathing?
The primary histological structures involved in breathing include the respiratory epithelium, alveoli, and the capillaries surrounding the alveoli. The respiratory epithelium is lined with ciliated cells and goblet cells that help filter and humidify the air. The alveoli are tiny sacs where gas exchange occurs, surrounded by a network of capillaries that transport oxygen and carbon dioxide to and from the bloodstream.
