Ancient Egyptian mummification involved sophisticated techniques to preserve soft tissues. The structure and elasticity of arteries are largely due to the presence of elastic fibers within their walls. Effective embalming methods that preserved the protein structure of these elastic fibers would contribute significantly to the intactness of the arteries over millennia.

The structural integrity of arteries, including their elasticity, is primarily attributed to the presence of elastic fibers. Preservation of these fibers through mummification techniques helps keep the arteries intact.

Fibroblasts produce collagen and other matrix components, including the precursors of elastic fibers, but the mature elastic fiber itself provides the elasticity. Mineralized blood might refer to calcification or remnants within the vessel lumen, but it doesn’t explain the preservation of the vessel wall structure. Brown fat is a type of adipose tissue involved in thermogenesis and is not a structural component of arteries. Mummification processes often involved the removal of organs and treatment of tissues with various salts and resins to dehydrate them and inhibit microbial decay, preserving their structural components like elastic fibers.
