Final answer:
Areolar tissue, also known as loose connective tissue, is a type of connective tissue that fills spaces between muscle fibers, surrounds blood and lymph vessels, and supports abdominal organs. It is found beneath most epithelial tissues and forms the connective tissue component of epithelial membranes.
Step-by-step explanation:
Areolar tissue, also known as loose connective tissue, is a type of connective tissue that shows little specialization. It contains all the cell types and fibers found in connective tissue, and is distributed in a random, web-like fashion. Areolar tissue fills the spaces between muscle fibers, surrounds blood and lymph vessels, and supports organs in the abdominal cavity. It is also found beneath most epithelial tissues and forms the connective tissue component of epithelial membranes. Areolar tissue is tough yet flexible, and comprises membranes.
