Fat tissue, also known as adipose tissue, is a type of connective tissue that stores energy in the form of fat. It plays a crucial role in regulating body temperature and cushioning vital organs. There are two main types of fat tissue: white fat, which stores energy, and brown fat, which generates heat by burning calories. In addition to energy storage, fat tissue also produces hormones that help regulate metabolism and appetite. Maintaining a healthy balance of fat tissue is important for overall health, as excessive fat can lead to conditions like obesity and related diseases, while too little fat can affect bodily functions.
