WebThe lower respiratory system's job is to make the process of exchanging gases between the body and the outside environment as easy as possible. Although the trachea, bronchi, and bronchioles are responsible for transporting air, the alveoli provide a huge surface area for the process of gas exchange to take place. 6.

WebGas exchange occurs only in alveoli. Alveoli are made of thin-walled parenchymal cells, typically one-cell thick, that look like tiny bubbles within the sacs. Alveoli are in direct contact with capillaries (one-cell thick) of the circulatory system. WebJun 16, 2024 · Gas exchange between the lung and blood takes place in the alveolus. From the nasal cavity, air passes through the pharynx (throat) and the larynx (voice box), as it makes its way to the trachea (Figure 9.2. 6 ). The main function of the trachea is to funnel the inhaled air to the lungs and the exhaled air back out of the body. WebJun 9, 2024 · The alveolar membrane- is where gas exchange between the blood and the atmosphere takes place. The gas molecules must diffuse across the alveolar epithelium and the capillary endothelium. ... Thus, the alveolar surface (as well as the respiratory bronchioles) have no cilia or mucus layer.
