Question

which cells produce fluid or lubrication for the lungs? fat cells glandular cells mesothelial cells endothelial cells

Explanation:

• Fat cells: Store fat, not related to lung lubrication.
• Glandular cells: Secrete substances like hormones or enzymes, not lung - specific lubrication.
• Mesothelial cells: Line body cavities (including the pleural cavity around the lungs) and produce serous fluid for lubrication.
• Endothelial cells: Line blood vessels, not involved in lung lubrication.

Mesothelial cells
