Types of Adipose Tissue. Adipose tissue can be classified by morphology into white, brown, or beige subsets. In addition, white adipose tissue (WAT) can be broadly classified by location, largely defined as subcutaneous (located under the skin) and visceral/omental (located intra-abdominally, adjacent to internal organs).Adipose tissue is
