SOLUTION DIGEST
◉Fluid outside cells; sometimes called tissue fluid, and includes
plasma . Answer: Extracellular Fluid (ECF)
◉Glands that secrete substances outward through a duct . Answer:
Exocrine Glands
◉Glands that produce sweat; found over most of the body. Found in
the dermis; sometimes hypodermis. . Answer: Eccrine Glands or
Merocrine Glands
◉Sweat glands in the pubic and underarm areas that secrete thicker
sweat, that produce odor when come in contact with bacteria on the
skin . Answer: Apocrine Glands
◉Ductless glands that empty their hormonal products directly into
the blood.
, For example: thyroid, adrenal, and pituitary glands . Answer:
Endocrine Glands
◉Exocrine glands whose secretions are made up of disintegrated
cells.
For example: oil glands of scalp and skin, and glands of eyelids .
Answer: Holocrine Glands
◉Sheets of tightly packed cells that covers body surfaces, lines body
cavities, and forms glands . Answer: Epithelial Tissue
◉- Single layer of flattened cells
- Permits rapid diffusion or transport of substances
- Secretes serous fluid
- Locations: alveoli, glomeruli, endothelium, and serosa . Answer:
Simple Squamous Epithelium
◉- Single layer of square or round cells
- Responsible for Absorption and secretion, mucus production and
movement
- Locations: liver, thyroid, mammary and salivary glands,
bronchioles, and kidney tubules . Answer: Simple Cuboidal
Epithelium
