The disease is characterized by infiltration of the connective and perivascular tissue by foamy histiocytes that stain positively for CD68, CD163, and factor XIIIa. The fibers which compose the connective tissue are also soluble proteins that form during the clotting process, much like those found in the hematopoietic tissue. Each connective tissue acts to support and hold your body together and, in some instances, transmit substances around your body. There are three main components to connective tissue: cells, ground substance, and fibers. Has mostly collagenous fibers in a regula, parallel alignment like the strands of a cable. Dense regular tissue is made out of tightly packed clumps of collagen fibers, running in parallel directions. Blood, also referred to as vascular tissue, is a type of fluid connective tissue. Connective Tissue : Connectvie tissues of animals serve the functions of binding and joining one tissue to another (i.e. It contains leukocytes cells and is made of fibers which are soluble liquid proteins that form during clotting. Blood connective tissue is comprised of three different kinds of cells: leukocytes, thrombocytes, and erythrocytes. Adipose, or fat, tissue is an example of a connective tissue that facilitates the storage, absorption and disposal of nutrient, vitamins, minerals and other substances. Lymph nodes, adenoids, the spleen, and tonsils are all examples of lymphatic tissue. This tissue can pull in one direction. Connective tissue is made up of a small fraction of cells and a majority of extracellular substance which keeps the cells separated.
