Final answer:
The dermis is a layer of the skin that performs various functions, including cushioning subcutaneous tissues, regulating body temperature, sensing the environment, and excreting wastes.
Step-by-step explanation:
The dermis is a layer of the skin that consists of connective tissues and structures such as glands and hair follicles. It plays several important roles in the body:
- Cushioning subcutaneous tissues: The dense connective tissues of the dermis provide cushioning for the underlying tissues.
- Regulating body temperature: The dermis helps regulate body temperature through sweating and vasodilation or vasoconstriction.
- Sensing the environment: The dermis contains tactile sensory receptors that enable the sense of touch.
- Excreting wastes: Sweat excreted by sweat glands in the dermis contains excess water, electrolytes, and metabolic wastes.
