Answer :
The desirable characteristics for a gas exchange surface, such as the endothelial cells lining the inside of a lung have- a large surface area, a thickness under 10 micrometers.
Hence the correct option is 1 and 4.
All blood arteries are lined by a single cell layer called the endothelium, which controls how the circulation communicates with the tissues around it. The growth and development of connective tissue cells, which make up the outer layers of the blood artery wall, is orchestrated by signals from endothelial cells.
The big and tiny capillaries of the lung are lined with endothelial cells, which are an active component of the lung. They all participate in creating a barrier, but they also actively participate in both healthy and unhealthy lungs.
Endothelial cells vary in form throughout the vascular tree, but they are typically thin and somewhat elongated, measuring around 50–70 m in length, 10–30 μm wide and 0.1–10 μm thick.
The complete question is:
