Fatty tissues, also known as adipose tissues, are specialized connective tissues that store energy in the form of fat. They play a crucial role in regulating body temperature and cushioning organs. There are two main types: white adipose tissue, which stores energy, and brown adipose tissue, which generates heat. These tissues are composed of fat cells called adipocytes, which can expand or shrink based on energy intake and expenditure. Fatty tissues also produce hormones and other substances that help regulate metabolism and overall health, making them important for maintaining a balanced body function.
