Blood Vessels Smooth Musculature on the right
Need for solidification of the vascular wall (arteries and veins).

During vessel wall necrosis, the smooth muscle layer simultaneously thickens, preventing vessel perforation.
In the cl-phase, vessel wall necrosis is repaired (athero- or arteriosclerosis). The reinforced vascular smooth muscle remains thickened.
locally increased peristalsis
Simultaneous smooth muscle thickening during Intima vascular necrosis is a useful germ layer-spanning combination.
