Explanation:
The most important role of white adipocytes is energy storage. They store fat in the form of triglycerides inside their cytoplasmic lipid droplets, which helps to maintain free fatty acid levels in the blood.
For a long time, adipose tissue has been considered only as a passive fuel reservoir. Now, it is also considered to be an endocrine organ which secretes several bioactive factors (hormones, growth factors, cytokines). The most important adipose tissue hormones include leptin (satiety factor) and adiponectin. These biofactors circulate through the organism and carry information to other metabolically active organs such as liver, pancreas, muscle, and brain. These factors are of key importance in the pathophysiology of many metabolic disorders (e.g. type 2 diabetes mellitus).
Different localizations of the adipose tissue have different roles in the human body. For example, abdominal fat has a different metabolic profile than the rest of the fat in the body, and it has the biggest influence in inducing insulin resistance. Parietal fat has an important role in thermoregulation, while visceral fat provides the cushion-like support for internal organs, protecting them from mechanical injuries. During reduced caloric intake, the amount of parietal adipose tissue decreases, while the visceral fat remains undiminished.
In contrast to white, brown adipose tissue transforms chemical energy into heat. That way it prevents obesity, other metabolic disorders, and hypothermia.
Adipose tissues are found beneath the skin, around kidney and in buttocks. Some of the locations of adipose tissue are-
Between the bone joints.
Beneath the skin.
Around the kidneys.
Around heart.
The Functions of adipose tissue-
The thick layer of adipose tissues helps to reduce heat loss through skin.
It provides mechanical protection.
It provides support to major organs like kidneys.
It serves a source of energy storage
