Connective tissues job is to either connect biological components like bones and muscles together or to hold tissues like muscles, tendons, and even organs in their right location in the body. Connective tissues are divided into three that are loose connective tissue, dense connective tissue and specialised connective tissue. Connective tissue also forms layers that separate tissues and organs. Soft tissues and organs are supported and protected by bones. and blood provide protection against toxins and tissue injury, as well as Cartilage is avascular, while dense connective tissue is poorly vascularized.

When someone starts losing weight, the size of the fat cells decreases or shrinks. Bone is a rigid connective tissue with considerable strength that resists pressure and bending stress better than cartilage, but it is less flexible, meaning it does not spring back when stressed. How do I choose between my boyfriend and my best friend? These fibres occur in bundles. As the name implies, regular elastic dense connective tissue provides elastic characteristics to the organ in which it is found, allowing it to stretch and generate a certain degree of flexion when coupled with rigid parts. It is the primary circulating fluid involved in the transportation of numerous chemicals. Collagen fiber is mostly found in dense connective tissue. Abstract The choroid of the eye is a vascularized and pigmented connective tissue lying between the retina and the sclera. Teach and inspire while you could & smile while you have teeth, Connective tissue binds various tissue together and form structural framework for the body, Areolar connective tissue serves as a support framework for epithelium.
