What are two examples of loose tissue?

• A. Tendons and ligaments
• B. Adipose (fat) and areolar (subcu tissue)
• C. Bone and cartilage
• D. Haematopoietic tissue and lymph

Answer: (B)

Loose connective tissue is defined by a loose, open arrangement of fibers and a relatively abundant ground substance, which allows flexibility, movement of fluids, and space for immune cells. Two classic examples are adipose tissue, which stores fat and provides insulation and cushioning for organs, and areolar tissue, a loose network under the skin and mucous membranes that supports vessels and nerves and acts as a filler between tissues. These tissues have cells scattered within a loose matrix, giving them a soft, pliable character.

Tendons and ligaments, by contrast, are dense connective tissue with tightly packed collagen fibers designed for strength and resistance to tension. Bone and cartilage are rigid, specialized supportive tissues, not loose. Haematopoietic tissue and lymph are specialized tissues involved in blood cell formation and immune function, rather than loose connective tissue.
