Final answer:
Connective tissue is the most abundant type of primary tissue in the body and is ubiquitously found throughout, performing various supportive, protective, and storage functions, so the response to the question is (a) True.
Step-by-step explanation:
Connective tissue is indeed the most abundant primary tissue in the body and is found "everywhere," making the statement (a) True). Connective tissues serve various functions from providing support and protection to the soft parts of the body, to storing energy reserves, and facilitating motion.
Fibrous connective tissue contains large amounts of collagen fibers and can be found throughout the body, acting as a packing and binding material for most organs. It is divided into types: irregular, which handles multi-directional stress and is found in the dermis, and regular, which aligns in parallel strands found in tendons and ligaments.
Another type, loose or areolar connective tissue, includes a mix of fibroblasts, macrophages, and collagen and elastic fibers, providing a loose consistency that is tough yet flexible. This tissue type is found surrounding blood vessels and helps to keep them in place, as well as being present between most body organs.
Beyond fibrous and loose connective tissues, the body also has supportive connective tissue like cartilage and bone, and fluid tissue such as blood and lymph, all of which contain an organic matrix material that confers strength and flexibility.
