Explanation:
The process of gas exchange in the lungs occurs through the thin walls of the alveoli and the pulmonary capillaries. The exchange of gases (oxygen and carbon dioxide) takes place across the respiratory membrane which separates the air in the alveoli from the blood in the pulmonary capillaries.
The respiratory membrane is composed of three layers:
1. Type I alveolar cells: These cells make up the walls of the alveoli and are extremely thin, allowing for easy diffusion of gases.
2. Endothelial cells: These cells make up the walls of the pulmonary capillaries.
3. The basement membrane: This layer separates the two cell types and provides structural support.
The correct answer to the given question is option B - squamous epithelium endothelium of blood vessel. This means that the respiratory membrane is composed of type I alveolar cells and endothelial cells.
The squamous epithelium refers to the type I alveolar cells, which are extremely thin and allow for easy diffusion of gases. The endothelium refers to the layer of cells that make up the walls of the pulmonary capillaries.
The respiratory membrane is designed in such a way that it allows for the rapid exchange of gases between the air in the alveoli and the blood in the pulmonary capillaries. This is essential for the delivery of oxygen to the body's tissues and the removal of carbon dioxide, which is a waste product of cellular respiration.
In conclusion, the air-blood barrier in the lungs is composed of squamous epithelial cells (type I alveolar cells) and endothelial cells (of the pulmonary capillaries), which form the respiratory membrane.
