In most vertebrates, the stomach is located between the esophagus and the small intestine. It secretes protein-digesting enzymes called proteases and gastric acid to aid in food digestion, through smooth muscular contractions before sending partially digested food (chyme) to the small intestines.
Anatomical features. In humans, adipose tissue is located beneath the skin (subcutaneous fat), around internal organs (visceral fat), in bone marrow (yellow bone marrow), intermuscular (Muscular system) and in the breast tissue. Adipose tissue is found in specific locations, which are referred to as adipose depots.
Adipose Tissue is a loose fibrous connective tissue that is packed with many fat cells (called  adipocytes ): Adipose tissue forms a thick layer under the skin, around the kidneys and in the buttocks. More generally, it is found at the same locations throughout the body as areolar connective tissue. Adipose tissue acts as an insulating layer, helping to reduce heat loss through the skin. 2  It also has a protective function, providing mechanical protection (padding) and support around some of the major organs, e.g. kidneys. 3  Adipose tissue is also a means of energy storage.
