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. Three layers under the skin. Lying three layers deep under the skin, the adipose tissue is composed of a loose collection of specialized cells, called adipocytes, embedded in a mesh of collagen fibers. Its main role in the body is function as a fuel tank for the storage of lipids and triglycerides.
