Question

Describe why the animals of colder regions and fishes of cold water have a thicker layer of subcutaneous fat.

Answer 1

Hint: Body fat is a term used to describe adipose tissue. It can be found in every part of the body. It's found beneath the skin (subcutaneous fat), surrounding internal organs (visceral fat), between muscles, in bone marrow, and in breast tissue. Men are more likely to store visceral fat (fat around their internal organs), which can lead to obesity in the centre of their belly. Women, on the other hand, retain more subcutaneous fat in their buttocks and thighs. The sex hormones produced by males and females cause these disparities.

Complete answer:
The fat depositing layers situated just beneath the skin or between internal organs are known as subcutaneous layers or adipose tissues. They operate as a good insulator and prevent heat loss from the body. Cold-blooded animals and cold-water fish have a thicker layer of subcutaneous fat to keep heat in their bodies and maintain body temperature. The less heat is lost from the body, the thicker the layer of subcutaneous fat.
There are five main roles of subcutaneous fat.
It's the only way your body can save energy.
It acts as padding, protecting your muscles and bones from the impact of falls or impacts.It connects your skin and muscles by providing a pathway for nerves and blood vessels. It insulates your body and aids with temperature regulation. With its specific connective tissue, it connects the dermis to the muscles and bones.
Because fat functions as a good insulator and traps body heat under the skin, animals in colder climates and cold-water fish have extensive subcutaneous fat layers. This aids their survival in colder climates.
Adipose tissue is now widely recognised as a vital and functioning endocrine organ. Adipocytes (or fat cells) are widely known for their involvement in the storage and release of energy throughout the human body. The endocrine function of adipose tissue has just lately been discovered. Adipocytes are just one type of cell in adipose tissue, which comprises a variety of other cells that can create hormones in response to signals from the rest of the body's organs. Adipose tissue regulates glucose, cholesterol, and sex hormone metabolism through the effects of these hormones.

Note:-
Both too much and too little adipose tissue can be harmful to one's health. Obesity is more usually caused by excess adipose tissue, particularly visceral fat. Obesity causes a slew of major health issues. Obesity increases the risk of type 2 diabetes by causing the body to become insulin resistant. High blood sugar levels come from this resistance, which is harmful to one's health. Obesity also increases the risk of high blood pressure, high cholesterol, and a blood clotting tendency. All of these factors increase your chances of having a heart attack or stroke.
