- ANSWER: Epidermis and dermis.
What is the epidermis?
- ANSWER: The outermost protective layer of dead keratinized epithelial cells.

What does the protein pigment melanin protect against?
- ANSWER: Radiation from the Sun
What is the dermis composed of?
- ANSWER: Fibrous connective tissue with nerve endings, blood vessels, sensory nerve
endings, hair follicles, and glands.
What are the 2 types of sweat glands?
- ANSWER: ecrine & apocrine
What do ecrine sweat glands produce?
- ANSWER: Sweat. Regulate body temperature.
What do apocrine sweat glands produce?
- ANSWER: Secretions contain bits of cytoplasm from cells, attracting bacteria that
produces body odor.
What do sebaceous glands secrete?
- ANSWER: They secrete sebum through the hair follicles, which lubricates the skin and
prevents drying.
