Explanation

All cells of connective tissue except blood secrete fibres. Fibroblasts are the main cells of connective tissue, which secrete various types of fibres. There are three types of fibres secreted by connective tissue cells and each type of formed by proteins. These are collagen fibres (made up of collagen protein). elastic fibres (formed of elastin) and reticular fibres (made up of reticulin). All provide strength, elasticity and flexibility to the connective tissue.
