Answer 1

In Integumentary system blood vessels are found in dermis and the blood vessels contract when the body is cold.
Dermis and epidermis are layers of the skin, dermis is the thick layer of tissues and it is present under the epidermis layer.
When we feel cold, our body supplies the warm blood to the skin. When contraction of blood vessels occurs, it reduces the flow of warm blood and reduces the heat loss. When we feel hot, blood vessels dilate.
