Ultraviolet (UV) radiation is known to damage skin. UVA wavelengths are able to reach the dermis, whereas UVB wavelengths are only able to penetrate the epidermis. Excessive exposure can cause enough damage to stimulate acute inflammation (sunburn). Histamine secretion initiates the inflammation. Select the TWO that are likely to be true: O vitamin D activation will decline blood flow to the affected area will increase O UVB activates Pascinian corpuscles O UVB activates mast cells O UVA activates mast cells blood flow to the affected area will decrease
