What tissue is important in conserving body heat?
A. The dense connective tissue in the dermis.
B. The areolar tissue of the papillary layer.
C. The stratified epithelium in the epidermis.
D. The adipose tissue in the subcutaneous layer.
Answer (2)
The adipose tissue in the subcutaneous layer is crucial for conserving body heat as it provides insulation and energy storage. This layer of fat helps maintain body temperature, especially in cold environments. Therefore, the correct answer is option D.

The tissue important in conserving body heat is (D) the adipose tissue in the subcutaneous layer.
Adipose tissue is a type of connective tissue that stores fat. It is located in the subcutaneous layer, which is just beneath the skin. This tissue acts as an insulating layer that helps to conserve body heat by reducing heat loss through the skin. Fat cells, also known as adipocytes, contain stored energy and can produce heat when the body needs to maintain its internal temperature.
Here’s why adipose tissue is specifically important for conserving body heat:
Insulation : Adipose tissue acts as a natural insulator. The fat stored within the cells serves to trap heat and maintain body temperature.
Energy Reserve : Fat stored in adipose tissue can be converted into energy, which is crucial in temperature regulation. When the body recognizes a drop in temperature, it can metabolize these fat stores to generate heat.
Protection : Besides heat conservation, adipose tissue also cushions and protects vital organs and structures in the body.
In contrast, the other tissue options perform different functions:
Dense connective tissue in the dermis (A) : It provides structural support but is not specialized in conserving heat.
Areolar tissue of the papillary layer (B) : Acts as a binding tissue but does not significantly aid in insulating the body.
Stratified epithelium in the epidermis (C) : Offers a protective barrier to external factors but does not specialize in heat conservation.
