BIOLOGY 150 UPDATED COMPREHENSIVE EXAM
QUESTIONS AND ANSWERS SURE A+
✔✔What are the functions of connective tissue? - ✔✔Physical protection, support,
binding parts of the body, storage, and transport.
✔✔What is epithelial tissue? - ✔✔Tissue that covers surfaces or lines cavities and is
glandular.
✔✔What are the characteristics of epithelial tissue? - ✔✔Cells are tightly bound, one
surface is exposed, lacks blood vessels, and regenerates quickly.
✔✔What functions does epithelial tissue serve? - ✔✔Protection, absorption, secretion,
and sensation.
✔✔What is the largest organ of the body? - ✔✔The skin.
✔✔What are the three layers of the skin? - ✔✔Epidermis, dermis, and hypodermis.
✔✔What is the outer layer of the skin called? - ✔✔Epidermis.
✔✔What type of cells primarily make up the epidermis? - ✔✔Keratinocytes.
, ✔✔What is the function of keratin in the skin? - ✔✔Provides strength and protection.
✔✔What are the layers of the epidermis? - ✔✔Stratum basale, stratum spinosum,
stratum granulosum, and stratum corneum.
✔✔What is the function of melanocytes in the skin? - ✔✔Produce melanin, which gives
skin its pigmentation.
✔✔What is the role of Langerhans cells? - ✔✔Immune system cells that detect
microbial threats.
✔✔What are the two layers of the dermis? - ✔✔Papillary and reticular layers.
✔✔What type of connective tissue is found in the papillary layer of the dermis? -
✔✔Areolar connective tissue.
✔✔What is the hypodermis also known as? - ✔✔The subcutaneous layer.
✔✔What is the primary function of adipose tissue? - ✔✔Stores fat and acts as a
protective cushion.
✔✔What are the two types of sweat glands? - ✔✔Merocrine and apocrine glands.
✔✔What is the main function of merocrine sweat glands? - ✔✔Produce perspiration to
reduce body temperature.
✔✔What is a first-degree burn? - ✔✔A burn that only damages the epidermis.
✔✔What are the effects of aging on the skin? - ✔✔Thinner epidermis, fine wrinkles,
decreased collagen, deep wrinkles, and sagging skin.
✔✔What causes skin color differences? - ✔✔Type and density of melanin, and how
long melanin persists in keratinocytes.
✔✔What is the role of sebaceous glands? - ✔✔Secrete oil to prevent skin and hair from
drying out.
✔✔What is the primary focus of BIOL 150? - ✔✔The study of human anatomy, including
organization, cellular anatomy, and the skin as an organ.
✔✔What are the learning objectives of the course? - ✔✔Identify visible tissues and
organs, connect structural characteristics to functions, and relate interactions of tissues
and organs to organ systems.
