c. maintain a relatively constant body temperature despite external temperatures.
d. may have feathers to keep them insulated.
e. none of the above
Tissues are an assemblage of cells that perform a specific function attributed to their structure. Hence, function follows form. In higher animals, tissues are assembled to form organs, where organs form organ systems. Animal tissues are grouped into 4 general types - epithelial, connective, muscle, and nervous. Epithelial tissues are those that tissues that act as barriers in the body, forming linings or organs and cavities as well as making up the skin. The cells in epithelial tissue are densely packed due to tight junctions aiding in their protective function. Connective tissues are those that, as their name implies, connect and provide support to other tissues. Connective tissue is much less dense than epithelial tissue and is composed of proteinaceous fibers ...
Includes a detailed explanation of the 4 basic animal tissue types with examples and illustrations, including sources. Also contains a discussion regarding homeostasis, especially the control of core temperatures.
