6 True/False questions
evaporation → heat is lost from a warm object to the cooler air currounding the warm object.
cutaneous membrane → It lies under the skin and is called the hypodermis. Composted of loose connective and adipose tissue. Helps to insulate the body from extreme terperatures and anchors skin to the underlying structures. A few areas have no subcutaneous layer, so the skin anchors directly to the bone.
stratum corneum → the surface area of epidermis. Composed of 30 layers of dead, flattened keratinized cells.
dermis → outer layer of the skin
stratum germinativum → the surface area of epidermis. Composed of 30 layers of dead, flattened keratinized cells.
thermoregulation → occurs when liquid becomes a gas. ie. rub liquid alcohol on the skin. It evaporates and cools the skin.
