On the camping adventure the epidermis will protect me on my adventure by producing melanin to protect me from ultraviolent waves that can damage the skin. Also, theepidermis has stratus layers that keep bacteria out and other infectious things. Theepidermis is in generally the protective layer and acts as a barrier. The dermis controls your body temperature, when I get hot I will sweat because the dermis controls the sweat glands. When exercise, maybe go on a hike the contractions of my muscle make my blood vessels expand to allow more blood flow through my body, the blood vesselsare controlled by my dermis
The answer is red blood cells because they only give your body oxygen and can be the victims of infectious diseases, while all the other choices protect you from it
