It's like hair. Hair cells are dead, if they were alive, imagine how painful a haircut would be. About three layers of your skin is dead, which makes lacerations more tolerable. I'm not sure but maybe it's a natural defence. If all your skin were alive, could you imagine sunburns? And even being touch by heat would hurt. We would be very sensitive if that were the case... yes, I think it's to protect. But I am not an expert.
As the most superficial layer of skin, the epidermis is composed of dead cells. The epidermis serves as a tight waterproof barrier to protect us from foreign bodies that would cause us harm, and keeps the tissue deeper in our body from drying out. In order to form this type of barrier there can't be blood flow to the epidermis. Without blood flow, the cells cannot live.
It is an advantage because,if you get hurt in any way,newly-formed cells will not be damaged.
Nothing, epidermis cells only live a short while (about 2 weeks) and the dead ones are just waiting to be swept off. Correct me if I am wrong.
It is important because it gives us fresh skin cells. It keeps our body protected. We have new skin that will heal faster.
To protect ones body
So you can show off your new skin
Yes, any living thing is made up of cells, that includes plants and trees.
He was a botanist. He showed that plants are made up of cells
Humans are made up of tiny cells.
It is a structure in eukariyotes. So they have eukariyotic cells
The common and the most important rule for the cells is that they are "the building blocks of body".They are as important to us as a brick is important to a house.Cells made up a tissue , tissue made up organs and organs together made up a human body.
No, the epidermis is made up of mostly dead cells
Yes, it is made up of living and dead cells.
The epidermis is the top and most superficial skin layer in the body and is made of dead skins cells. You will shed these dead skin cells and they will fall., so you don't have a continuously growing layer of dead skin.
Epidermis
the stratum basale
dead cells
The epidermis is made up of dead skin cells. The cells are constantly falling off of the body, but are replaced by new cells that were earlier created in the dermis.
Epidermis
Dead skin cells break away from the epidermis and they fall off. This makes room for the newer skin cells. The dead cells fall off as you go about your daily life and they can end up in your bed and around your house.
Yes but your skin shreds everyday so you may have layers of dead skin forming on the surface of your skin. We shred quite a lot of skin cells everyday but if you're talking about actual layers of skin in which blood runs through then yes, those cells are indeed alive . :)the outer layer is made up of dead cells.noThe layer is comprised of both living and dead cells.------------------------------------------------------------------------------Actually,The skin is made up of several layers. The epidermis is a layer with distinct sublayers.The outermost layer of the epidermis, the Stratum Corneum consists of dead cells and keratin.On the outside of the skin, there will usually be bacteria and yeast, generally in a balance. Perhaps there is the occasional macrophage.yes i learn it in my books
the top layer; the epidermis
Most of the skin is composed of the dermis which is made up mostly of dense irregular connect tissue. The cells about it are dead cells called the epidermis.
