Organs consist of two tissues. One deals with the function of the organ, and the other, the stroma, comprises the rest of the tissues, such as blood vessels and nerves. This stroma varies depending on the organ. For instance, the spleen is made up almost wholly of connective tissue. The bulk of the spleen consists of lymphocytes and other blood cells, while the stroma tissue is the supporting connective tissue. The main part of the brain consists of nerve cells and glia, while the stroma is the connective tissue and blood vessels.
