Cartilage is a connective tissue whose cells, called chondrocytes, secrete a very specialized matrix. The basophilia of the matrix is due to the GAGs in its ground substance, specifically hyaluronic acid, chondroitin sulfate and keratan sulfate.onnective tissue is the most diverse of the four tissue types with a wide variety of functions. It ranges in consistency from the gel-like softness of areolar connective tissue to the hardness of bone. Blood is also a connective tissue.
Chest radiographs most often show well defined linear and nodular densities which are characteristic of lung tissue disease. Each nodule represents mutiple coalescent granulomas since an individual granuloma is microscopic.his is why transbronchial biopsy has such a high diagnostic yield and is the favored means of obtaining tissue for diagnosis. The involvement of the lung parenchyma by sarcoidosis can have very different appearances ranging from reticulonodular lung tissue densities to multiple masses and miliary lesions.
