Adipose tissue, commonly known as body fat, is a type of connective tissue that stores energy in the form of fat. It plays a crucial role in regulating metabolism, providing insulation, and protecting vital organs. There are two main types of adipose tissue: white adipose tissue, which stores energy, and brown adipose tissue, which generates heat by burning calories. This tissue is composed of adipocytes, or fat cells, which can expand or shrink based on energy intake and expenditure. Hormones and enzymes regulate the formation and breakdown of fat, influencing overall body weight and health. Excess adipose tissue can lead to health issues, including obesity and related diseases.
