Answer:
d. The dermis releases oils that cover the skin, and the hypodermis releases heat from capillaries.
Explanation:
The skin, the largest organ of the human body, has an essential protective function against pathogens, such as bacteria. This organ is composed of three layers of tissue: the<em> epidermis, dermis </em>and<em> hypodermis.</em>
The dermal layer or dermis has a variety of characteristics that help achieve this purpose, for example:
- <u>The presence of oil or sebaceous glands</u>: These glands produce sebum to protect the skin from pathogens and pollutants.
- The presence of sweat glands.
- The presence of hair follicles.
- The presence of blood vessels.
The hypodermis is characterized by being the deepest layer of the skin but it also protects us from infections.
- It is composed of fatty tissue, which provides an insulating layer to protect us from extreme weather.
- This fat also protect us from severe injuries due to its thickness.
- The<u> blood vessels located in the hypodermis cause the capillaries to expand and release more heat. </u>
