The epidermis is the outer layer of the skin covering the exterior body surface of vertebrates. The epidermis provides waterproofing and protection, produces melanin and keratin and maintains the body's hydration levels.
The outermost surface of the skin is the epidermis.

a protective, physical barrier
The top layer of skin is called the epidermis, while the second layer is called the dermis.

The epidermis.
out layer of the skin
The answer is epidermis
There are three layers the Epidermis, Dermis and the Hypodermis. The layer of skin on the outside of your body is the Epidermis.
The outer layer of skin is the epidermis. It is the human body's largest organ.

The outermost layer of skin is called the epidermis.
That would be the epidermis.
The outer covering of the skin is the epidermis. This consists of two layers, outermost layer is called the stratum corneaum sometimes called the horny layer. Below this is the stratum germinativum.

1- Protection of the body against virulent organisms ("germs") and disease by acting as a first defense against disease-causing particles, because most can't get through unopened skin)

2- maintaining normal body temperature. (blood vessels in the skin can help to hold or release heat maintaining a constant temperature)

3- working as a sense organ (specialized nerve cells sense and relay info to the brain)

4- preventing the loss of water from the body.

5- excretion of waste by sweating. (sweat glands in the skin release waste in the sweat)

6- mechanical support of the body

7- protection of the body against dangerous UV rays

8- production of vitamin D (formed by ultraviolet light in fat molecules in your epidermis)

9- Langerhans cells working as an immune defense mechanism.

10- As an external shape, it helps humans in recognizing each other.It keeps germs out of the body,
to protect the body from foreign elements
We have skin so bacteria and germs keep out of our body and so we keep our blood, tissues and guts from spilling out of our body.
Skin is very important to the human body because it protects everything in the inside of your body. Skin protects all of your veins, blood vessels, arteries, and tissue. Skin is also a water proof covering that keeps you cool in the hot, and moderates your temperature. The three layers of the skin are the epidermis, dermis and subcutaneous layer. It's important to protect your skin from the sun; so you do not skin cancer. If you protect your skin, you will have less wrinkles and less freckles and beauty marks.

There are 7 layers in the human skin, the Epidermis has 3 layers and the Dermis has 4 layers, making the total to ∞ and beyond.

s is the outermost covering of the skin and serves as a barrier to infection. The dermis is below the epidermis. It serves as a location for the appendages of skin and buffers the body from stress and strain.

The hypodermis is not skin but subcutaneous adipose layer, and is responsible for connected muscle tissue, bone, and skin.
Three!

I'm pretty sure its 3 but it could be four

First off, let's define the word "excretory"

Excretion is the process of eliminating waste products of metabolism and other non-useful materials. It is an essential process in all forms of life. It contrasts secretion, where the substance may have specific tasks after leaving the cell

With that being said:

When you get hot, you sweat, sweat is an excretion - primarily made up of uric acid. Your skin, when you sweat is being cleansed at the same time as keeping you cool.

The sweat glands function as the excretory organs of the skin.

We sweat through our skins. The liquid that we release through the pours of our skin contains many toxins that are harmful to our body. This release of liquid is called excretion.

Your skin is made up of two layers that cover a third fatty layer. The outer layer is called the epidermis, and the second layer is called the dermis, which contains nerve endings, sweat glands, oil glands and hair follicles.

The most important cell type of the skin, in fact the one that can be actually said to form up the skin in common speak, are keratinocytes.

It should be noted that skin can be divided into epidermis, dermis, and hypodermis.

• Epidermis is made up of the aforementioned keratinocytes plus melanocytes, Langerhans cells, and the Merkels cell.
• In the dermis fibroblasts, smooth muscle cells, endothelial cells and various epithelial cellscan be found.
• Finally, in the hypodermis one can find adipose cells, distinct immune cells, nerve cells, and again fibroblasts, endothelial cells and various epithelial cells

Sebaceous Glands in the dermal layer of your skin make sebum. These glands are located at the base of hair follicles and helps keep the skin from drying out.

Thus, these glands are located in hair-bearing areas such as the face, axillae, and groin.
The gland that secretes sebum is called the "sebaceous gland" and it can be found in the skin of mammals and secretes that oily substance called sebum into the mammal's hair follicles and sometimes into the skin for lubrication.
sebaceous glands.

An organ is defined as a collection of different tissues performing the same function. The skin includes epithelial, nerve, and vascular tissue, as well as connective tissue. Hence, skin is an organ as it is made up of tissue."it is an organ, because it can die and needs air."

That is actually not the case, tissue can die and needs air as well, so there is no distinction there. Skin is an organ, and NOT a tissue because:

Tissue is a group of cells (the building blocks of all living things) that aren't necessarily the same type of cell, but work together to carry out a certain task.

An organ however has many 'tissues', you could say, in it. This allows it to create the fluids and ingredients it needs to carry out a bigger task. Such as pumping blood (heart), sorting through air (lungs) and controlling the body's functions (brain).

Hope I helped, and created a better answer to the last one! ;)

Bye there!
because it can absorb many things
Because it's a body part made of collective tissues that form together to do a job.
No, the skin is an organ itself - it is, in fact, the largest organ of the body.
It is not only an organ, it is the biggest organ in the body. It is called an organ because it has a necessary function; a body will quickly die without skin. The skin helps control temperature, fluid balance and seals much of the body from harmful microbes, among other things.

The skin protects the skin from pathogens, which are known as bacteria, viruses and such. It also keeps your whole body in place, working together with the muscles and bones. But the skin is prone to damage from the sun.

Keratin in the skin protects underlying tissues from microbes, abrasion, heat and chemicals. Lipids released by lamellar granules inhibit evaporation of water from the skin surface, thus protecting the body from dehydration. oily sebum prevents hairs from drying out and contains bactericidal chemicals that kill surface bacteria. The acidic pH of perspiration retards the growth of some microbes. Melanin provides some protection against the damage effects of UV light.

Skin is the major organ in our body.it helps the body in many ways.

• PROTECTION;it protects the body from external environment such as chemicals,physical agents such as harmful sun i.e is ultraviolet rays and biological agents such as microbes.
• IT protects the internal organs and also forms water proof layer by depositing melanin on upper layers of cells.
• upper surface of skin contains specialised phagocytic cells such as langerhans which attack foreign substances and present them to lymph system.
• it also contains hairs.
• it also kills various microbes present on skin with their special secreations and kills them by which it produces special characteristic odor for each type of person
• it protects from harmful rays coming from skin by producing a special pigment called melanin.
• it also helps in secretion of some waste materials in form of sweat.
• it protects our body by maintaining HOMEOSTASIS that is by regulating body temperature.it controls temperature by excreting sweat during increased temperature conditions and also by contraction and dilation of blood vessels producing a cooling effect.
