Connective tissue, also known as connective tissue, are those types of tissues with great diversity that share a particular filling function, inhabiting the spaces between organs and other tissues, but also supporting the body, founding the material support of the body. These tissues comprise a heterogeneous group of organic tissues that are related in their origin starting from the embryonic mesenchyme derived from the mesoderm. Morphologically, the connective tissue is characterized by having the presence of different types of separated cells due to the large amount of intercellular material synthesized by these, another particularity of this tissue is the richness they have in intercellular material.
Among the main functions of connective tissue are filling, support, transport, storage, repair and defense; This makes up the immune defense system against the strange proteins found in bacteria, tumor cells, viruses, among others.
Among the types of connective tissues can be mentioned:
Adipose tissue: in this tissue the cells called adipocytes predominate, specialized in the storage of lipids, that is, the adipocyte-initiating lipoblasts that develop large amounts of collagen, however, adult adipocytes secrete little amount of collagen and lose the ability to divide. They are found below the dermis, cordoning off certain internal organs such as the kidney and the inner part of the center of the long bones; the function of this tissue is to protect and hold internal organs and other body structures in place.
Cartilage tissue: this type of tissue lacks blood vessels and is elastic, it is formed primarily by disseminated cells called chondrocytes and the extracellular matrix that contains a lot of collagen fiber, is gelatinous but with a consistency greater than that of connective tissue. We can find three types of cartilaginous tissues such as hyaline, fibrous and elastic.
Bone tissue: this tissue constitutes a variety of connective tissue that has great rigidity, with great resistance to traction and compression; It is formed by three types of cells that are: osteoblasts, osteocytes and osteoclasts, which are groups of cells whose job is to destroy the bone to remodel it.
Hematopoietic tissue: it is that tissue to which the production of blood cells corresponds, this is located in the spleen, in the lymph nodes, in the thymus and mainly in the red bone marrow. There are two types of hematopoietic tissue: lymphoid and myeloid.
Blood tissue: it is constituted by a liquid intercellular substance, located inside the blood vessels, it also helps to maintain the balance of the internal environment; The main functions of these tissues is to transport nutrients and oxygen from the digestive system and lungs to the rest of the cells in the body.
Connective tissue: the matrix of this type of tissue has a gelatinous consistency with characteristic cells such as fibroblasts, we can also find lymphocytes, macrophages and mast cells. These can be classified according to their types and density of fibers, into: loose connective tissue, elastic connective tissue, fibrous connective tissue, reticular connective tissue.
