Meat from any animal is composed of muscular fibres, but it necessarily contains those structures which were intimately associated with them, such as connective tissues, blood vessels, nerves, and lymphatic vessels, and more or less adipose tissue. Meat which is very fat contains comparatively little water, as well as less nitrogenous matter than lean meat.
