Question

Quizplus · Accepted Answer

Blisters result from a separation of the epidermis from the dermis, which can be caused by friction, burns, or other types of injuries. The fluid that accumulates in a blister is composed of serum, plasma, or blood, depending on the cause of the injury. Therefore, option A is the correct statement. Blisters do not normally originate in the subcutaneous layer or the dermis, although some types of blisters may affect these deeper layers of the skin. Option C is also incorrect, as blisters involve an accumulation of fluid under the epidermis, so they are not confined to this layer.
