Science Facts Thursday: Skin

This week we take a look at the largest organ in the human body. No, not the brain, but skin! would you believe it?!
We are covered head to toe in skin, it protects our other vital organs, and helps keep everything in.

We have two main layers of skin, the epidermis and dermis.  The epidermis is what we see on the outside. Under the dermis is a layer of fat cells called the subcutaneous layer, this layer of fat helps to keep us warm.

Sloth here is demonstrating one way how our body keeps warm, by shivering. Our muscles jerk to produce heat.

Melanin also absorbs the sun's harmful ultraviolet rays, which is why people with fair skin burn more easily than people with darker skin tones. This doesn't mean those with a darker complexion won't burn, so always make sure you apply a suitable suncream.

Here is a super summer song, apply suncream before listening.
