This type of connective tissue is formed by a cell known as an osteocyte. Connective tissue types blend into one another, and the transition points cannot be precisely identified. Embryologically, blood has the same origin as the other connective tissue types have and blood connects the body systems together bringing the needed oxygen, nutrients, hormones and removing the wastes.Due to these reason blood is characterised as connective tissue. u0001 Cardiac muscle. They are present in lacunae and secrete the matrix. 4. Like all tissue types, it consists of cells surrounded by a compartment of fluid called the extracellular matrix (ECM). Between these collagenous bundles, there are rows called Tendon Cells characterized by their triangular or rectangular shape. The connective tissue arises from the mesoderm layer (the middle layer of an embryo). Blood is considered a connective tissue because it has a matrix. 10. The proteins of the bone matrix called oseein. When a connective tissue has a high concentration of cells or fibers, it has proportionally a less dense matrix. They are termed connective tissue because their main function is to link and support all other tissues in the body. Muscle tissue c. Adipose tissue d.
