Information about White Adipose Tissue
White adipose tissue (WAT) or white fat is one of the two types of adipose tissue found in mammals (compare to brown adipose tissue). In humans, white adipose tissue composes as much as 20% of the body weight in men and 25% of the body weight in women. Fat is one of four biological molecules. It is a lipid.

Brown adipose tissue (BAT) or brown fat is one of the two types of adipose tissue (the other being white adipose tissue) that is present in many newborn or hibernating mammals as well as migratory birds. Its primary purpose is to generate body heat.

Connective tissue is one of the four types of tissue in traditional classifications (the others being epithelial, muscle, and nervous tissue.) It is largely a category of exclusion rather than one with a precise definition, but all or most tissues in this category are similarly:

Areolar connective tissue (or loose connective tissue) is the most widely distributed connective tissue type in vertebrates.

Location
It can be found in the skin as well as in places that connect epithelium to other tissues...... Click the link for more information.
Dense connective tissue, also called dense fibrous tissue, has collagen fibers as its main matrix element. It is mainly composed of collagent type I. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that manufacture the fibers.

adipose tissue or fat is loose connective tissue composed of adipocytes. Its main role is to store energy in the form of fat, although it also cushions and insulates the body.

Reticular connective tissue is a type of loose irregular connective tissue and has a network of reticular fibers (fine type III collagen) that form a soft skeleton (stroma) to support the lymphoid organs (lymph nodes, red bone marrow, thymus, and spleen.

Mucous connective tissue (or mucous tissue) is a type of connective tissue found during fetal development.
It is most easily found as a component of Wharton's jelly.

Mesenchyme (also known as embryonic connective tissue) is the mass of tissue that develops mainly from the mesoderm (the middle layer of the trilaminar germ disc) of an embryo. Viscous in consistency, mesenchyme contains collagen bundles and fibroblasts.

Cartilage is a type of dense connective tissue. It is composed of collagen fibers and/or elastin fibers, and can supply smooth surfaces for the movement of articulating bones.

Bones are rigid organs that form part of the endoskeleton of vertebrates. They function to move, support, and protect the various organs of the body, produce red and white blood cells and store minerals.

extracellular matrix (ECM) is the extracellular part of animal tissue that usually provides structural support to the cells in addition to performing various other important functions. The extracellular matrix is the defining feature of connective tissue in animals.

Reticular fibers or reticulin is a histological term used to describe a type of structural fiber composed of type III collagen. Reticular fibers crosslink to form a fine meshwork (reticulum).

Elastic fibers (or yellow fibers) are bundles of proteins (elastin) found in connective tissue and produced by fibroblasts and smooth muscle cells in arteries. These fibers can stretch up to 1.5 times their length, and snap back to their original length when relaxed.
