Cartilage is the third type of connective tissue. Many of us are familiar with this flexible tissue that makes up our nose and ears. Cartilage is strong due to the collagen fibers within its matrix, and it is resilient due to a gel matrix. Cartilage is also found in the body as a cushion within the skeletal system.or example, red and white blood cells are found in blood, which is a fluid connective tissue. Adipocytes are fat cells found in adipose tissue, or fat. And fibroblasts are cells found in large quantities in many different types of connective tissues.
