What does the integumentary system do?

The integumentary system, made up of the skin, hair, nails, sweat glands, and oil glands, provides a protective covering for the interior of the body. It helps prevent pathogens from entering our body. The integumentary system prevents dehydration, and it helps synthesize vitamin D. It provides waterproofing for the body, and controls body temperature. It provides a way for us to recognize each other, as well. The skin acts like a breathable, waterproof barrier wall. Hair, such as eyelashes and nose hair, still provides protection and prevention of particles coming into our body.
It protects the body from various kinds of damage, such as loss of water or abrasion from outside. Skin and hair and nails provide that help in humans. In other creatures different coverings, such as scales, do the same job.

What factors affect skin color?

the differences in skin color result from differences in the amount of melanin that melanocytes produce and in the size of the pigment granules.

The three pigments that affect skin color are:

1. Melanin 2. Hemoglobin 3. Carotene

Different skin colour is simply the result of different amounts of melanin - skin pigmentation - in the skin.

For example, the absence or lack of melanin in the skin results in a person being classed as an albino.

Pigments in the skin

Skin tone in people is determined by the amount & type of melanin pigment in the skin. People with ancestors froom sunny areas have darker skin tones than those with ancestors from areas with less sunlight.

Skin color is largely regulated by the amount of melanin present in the dermis. This is determined primarily by th genotype of the organism.

Skin color is caused by the amount of melanin, or pigment, in a persons skin. This is essentially genetically decided, but some things, like sunlight, stimulate the production of melanin.

Presence of melanin pigment

Melanin is what determines your skin and hair color. The more melanin you have the darker your skin/hair will be. The less melanin you have the lighter your skin/hair will be. Melanin is passed down in your genes.

by a thing called melanin you get more melanin from the sun and less without it melanin comes from rays in the sun enhancing your pigment

The epidermis, which is the top layer of skin, has special cells called melanocytes, some 60,000 in every square inch of skin. Melanocytes produce a dark pigment called melanin. Melanin gives skin its color. Black people do not have more melanin in their system. Everyone has the same amount of melanin in them. Melanin protects the body from the damaging effects caused by the sun. When the skin is exposed to sunlight, the melanocytes produce additional melanin. This is what creates the suntan.

Some of the substances that give the skin color are melanin, blood, lipofuscin and beta carotene.

White people are not "White". Their skin is pink (which is a shade of the color Red). Their origin is in Genesis 25:25 in the Bible.

Go to IsraelUnite.org to learn more about the origins of "Blacks" and "Whites".

Melanin, keratin, and hemoglobin.

polygenic traits The melanin in their skin is produced in different amounts based on adaptation from where their ancestor's liv (e.g. if your ancestors lived in a hot, sunny place your body would make more melanin so you wouldn't get sunburned as easily) Your skin color really depends on where your ancestors came from. Because, if you are on the darker side, that means that your ancestors probably came from a hot place like Africa or Mexico or the Middle east, but if you have white skin, your ancestors probably came from Norway, Germany, Russia, or any place that's in the north. This all comes down to adapting to your environment.

Is the skin the same all over your body?

yes, your skin is the same all over your body, but it differs in thickness. It is thickest on your back, palm of your hands and bottom of your feet. Skin is made up of 3 layers, Epidermis, Dermis and hypodermis. The epidermis is made up of 5 layers (Good, Sweet Girls Like Candy) Good- Stratum germinativum, it is the basal layer, Sweet- Stratum Spinosum, Girls- Stratum granulosum, Like- stratum lucidum and candy- stratum corneum. While the dermis is made up of 2 layers, the papillary and reticular dermis. Finally, the hypodermis which consists of macrophages(defense cells), fat cells and fibroblasts, among others.

What does skin do?

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.

How many layers of skin are on the human body?

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.

What do sweat glands do?

Sweat glands, also known as sudoriferous glands, produce perspiration that helps cool your body (that's why you sweat when it's hot).. Sweat is an excretory product that helps the body get rid of wastes. Some types of sweat glands also produce pheromones. Pheromones are chemicals that are released by the body to communicate with or attract others. The human body has between 2 million and 4 million sweat glands located on the lower part of the skin.

Why is skin considered an excretory organ?

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.


Yes it remves toxins from your body to mantain homeostasis by sweating which uses the endocrine and integumentary system.

What is the deepest layer of the epidermis?

Stratum germinativum (also known as stratum basale or basal layer) is the deepest layer of the epidermis. In this layer, mitosis generates new keratinocytes.

The epidermis is composed of 5 layers. From most superficial to most deep, those are:

1) stratum corneum

2) stratum lucidum

3) stratum granulosum

4) stratum spinosum

5) stratum basale

What makes up skin?

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

What glands produce sebum?

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.

Why is skin considered an organ?

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.

Is your skin an organ?

Actually, yes it is, and that's because comprises different tissues that perform a body function. It is one of your largest and most important for many reasons, one of which is that your skin absorbs vitamin D from the sun.

Skin is made of two main parts the Epidermis and the Dermis. Under the dermis is the subcutaneous layer which is not skin but composed of fat and other tissue that holds your skin to the muscle and underlying structures.

How does skin protect you?

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.
