Connective tissue can be divided into loose and dense connective tissue. Loose connective tissue - In this type, fibers are loosely entwined with many cells embedded. Adipose, or fat tissue, is an example of loose connective tissue. The subcutaneous tissue, or innermost layer of skin, is made up of adipose tissue, as well as areolar tissue, another loose connective tissue. If we pull on our skin, we can see that it moves around quite easily because of this loose connection.
Next, there is dense connective tissue. It has thicker, denser fibers and fewer cells. The matrix is made up mostly of collagen fibers, with fibroblasts arranged in rows. This type of connective tissue forms tendons andligaments, which attach muscle to bone and bone to bone, respectively.
Blood is a type of fluid connective tissue.
