The skin acts as a barrier against germs and also controls body temperature?

The answer is: True.

The skin is the largest organ of the human body, covering a surface area of approximately 2 square meters (22 square feet). It is made up of three layers: the epidermis, dermis, and hypodermis. The epidermis is the outermost layer and is responsible for protecting the body from the environment. The dermis is the middle layer and is responsible for providing strength and elasticity to the skin. The hypodermis is the innermost layer and is responsible for insulating the body and storing fat.

The skin has a number of important functions, including:

* Protection: The skin acts as a barrier against germs, chemicals, and UV radiation.

* Temperature regulation: The skin helps to regulate body temperature by sweating and shivering.

* Sensation: The skin contains nerve endings that allow us to feel sensations such as touch, pain, heat, and cold.

* Excretion: The skin helps to excrete waste products through sweat.

* Absorption: The skin can absorb certain substances, such as oxygen and vitamin D.
