Question

Which of the following helps in maintaining body heat?
(a)Sweat glands
(b)Connective tissue
(c)Adipose tissue
(d)Hair

Answer 1

Hint: In order to retain body heat, a specialized tissue composed of lipid-rich cells helps. The main purpose of this tissue is to store energy in the form of lipids (fat), as it constitutes around 20-25 percent of the total body weight in healthy individuals.

Complete answer:
Body temperature is mainly controlled by an area known as the hypothalamus in the brain. Through opening and closing sweat glands and contracting muscles, the hypothalamus sets the body's temperature and regulates it. By supplying a layer of insulation directly under the skin, adipose tissue controls body temperature.
Through its close connection with the sympathetic nervous system, the division of the nervous system involved in our fight-or-flight responses, the integumentary system helps control body temperature. Continuously controlling body temperature and initiating suitable motor responses is the sympathetic nervous system.
In the structural network of fibers, adipose tissue consists primarily of fat cells or adipose cells, which are specialized in synthesis and produce large fat globules. Mainly under the skin, it is found. There are two distinct types of adipose tissue in mammals: white adipose tissue and brown adipose tissue. The common type is the white adipose, which acts as an energy store during times of hunger. Brown adipose, which is primarily present in newborn animals, creates heat and actually absorbs energy.
So, the correct answer is, ‘Adipose tissue’.

Note: Adipocytes are the building blocks of adipose tissue. Two distinct types of adipose tissue comprise three types of adipocytes;
The key cells in white adipose tissue are white adipocytes. White adipose tissue stores excess calories ingested by individuals, which may result in obesity.
The important cells of the brown adipose tissue are brown adipocytes. Brown adipose tissue dissipates energy to maintain body temperature by producing heat.
Beige adipocytes, discovered in white fat tissue, have recently been discovered.
