Write the differences between dense  regular connective tissues,and dense irregular connective tissues. 

Explanation

Dense regular connective tissues primarily contain collagen fibres parallel bundles of tissues and a few elastic fibres. The major cell types tissues primarily contain collagen fibres in rows between many muscles and bones and withstands great tensile stress when pulling force is app elastic fibres. The major cell type is fibroblast. It attaches direction. This connective tissue is present in tendons, that attach skeletal tissue is present in tendons, that attach skeletal muscles to bones and ligaments attach one bone to another.
Dense irregular connective tissues have bundles of thick collagen fibres and fibroblasts which are arranged irregularly. The major cell type is the fibroblast. It is able to withstand tension exerted in many directions and provides structural strength. Some elastic fibres are also present. It is found in the skin as the leathery dermis and forms fibrous capsules of organs such as kidneys, bones cartilages, muscles, nerves and joints. Elastic connective tissue contains high proportion of elastic fibres. It allows recoil of tissues following stretching. It maintains the pulsatile flow of blood through the arteries and the passive recoil of lungs following inspiration. It is found in the walls of large arteries, ligaments associated with vertebral column and within the walls of the bronchial tubes.
