Question

What is the total thickness of diffusion membrane?

Answer 1

may be it's less than 1.5 nanometre

Answer 2

The total thickness of a diffusion membrane is approximately 0.2mm.

• Diffusion membranes are usually made of three different layers.
• These include two layers of squamous epithelium and the basement membrane lying between them.
• The combined thickness of these layers is less than one millimeter.
• The thickness should be kept minimum to facilitate efficient diffusion of the substance across the diffusion membrane.
• The diffusion membrane at alveoli, and at bowman's capsule in nephrons are a few examples.
