Which tissue type includes adipose and areolar as examples?

• A. Loose tissue
• B. Solid tissue
• C. Fluid tissue
• D. Epithelial tissue

Answer: (A)

Adipose tissue and areolar tissue are both types of loose connective tissue. This category has a relatively open arrangement of fibers and plenty of ground substance, making it flexible and well-suited to cushion, support, and nourish other tissues. Areolar tissue is the classic example, with a loose network of collagen and elastic fibers and various cells that keep the tissue hydrated and connected to surrounding structures. Adipose tissue specializes in storing fat within adipocytes, which also helps cushion and insulate organs. This distinguishes them from dense connective tissue, which has tightly packed fibers; fluid tissue like blood and lymph, which have a liquid matrix; and epithelial tissue, which forms linings and coverings rather than a connective tissue framework.
