Connective tissue :
A loosely spaced tissue mainly carrying different materials to different parts of the body as well as rendering support, making connection between organs is called connective tissue.
Blood is considered as connective tissue because of the following reasons.
1. Blood connects different organs of our body together by carrying oxygen, nutrients, hormones and other signaling molecules and removing the waste.
2. It has all the three components of connective tissue i.e., cells, fibers and matrix.
3. Similar to other connective tissues, blood is rich in fibres like collagen fibers and blood clotting fibres.
4. Blood originates from the mesodermal layer of the embryo from which all other connective tissues also originate.
