4. What is the function of epithelial cells?
Answer Cover, line, and protect the body and the internal organs.
5. What is the function of connective tissue?

7. What ability does muscle tissue have?
Answer Ability to contract and shorten.
8. What is muscle tissue classified as?
Answer Voluntary(skeletal muscles) and involuntary(smooth & cardiac)
9. What is meiosis?
Answer The cell division that takes place in the gonads, i.e. the ovaries and testes.
10. What two layers compose the skin?
Answer Epidermis and dermis.
11. What is the epidermis?
Answer The outermost protective layer of dead keratinized epithelial cells.
12. What is the dermis?
Answer The underlying layer of connective tissue with blood vessels, nerve endings, and the associated
skin tissues.

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