Under The Skin

The integumentary system consists of the skin, hair, nails and other structures. The skin is the largest organ in the body and protects us from outside invaders that can cause disease, such as bacteria and viruses. It also provides us with vitamin D, which is vital for our bones and teeth.

Our hair and nails provide additional protection for our bodies. Our hair protects our head from cold weather, sunlight and injury. Our nails protect our fingers and toes from injury.

Do you know what type of skin you have? There are three basic types of skin: normal skin, dry skin and oily skin. Normal skin is neither too dry nor too oily. Dry skin tends to feel tight and itchy, while oily skin may feel greasy or shiny.

The integumentary system works with other systems in the body to protect us against infection. When we cut ourselves or injure our skin, an inflammatory response begins that stops bleeding and helps the wound heal by making the area red and swollen. This reaction helps the immune cells fight off any bacteria or viruses that may be present in the wound.

Skin cancer is a disease that involves uncontrolled growth of abnormal cells on or beneath the surface of the skin. Any part of the body can develop cancer, including areas not

The integumentary system is a very important system in the body. It helps to protect the body from viruses, bacteria and fungi that can cause disease. It also assists in regulating the body’s temperature by insulating the body, sweating and shivering, and absorbing and reflecting UV rays from the sun. This system also displays important organs such as sweat glands and hair follicles.

The integumentary system consists of sweat glands, sebaceous glands (oil), nerve endings, blood vessels, lymph vessels, and hair follicles. The skin is one of the most complex organs in the body. The skin is made up of two layers: the outer layer (epidermis) and the inner layer (dermis). The epidermis is made up of dead cells that are constantly being replaced by new cells from below as they are pushed up towards the surface. These dead cells help to create a barrier between your internal organs and the external environment. They help to prevent liquids from leaving or entering your body.

The dermis contains many nerve endings that allow you to feel hot, cold, pain and pressure. It also contains tiny blood vessels that carry oxygen and nutrients to the epidermis so it can survive without its own blood supply. Sweat glands

The integumentary system is the largest organ system in your body. It is made up of the skin, hair, nails and glands. The main role of the integumentary system is to act as a barrier for your organs.

The skin

The skin consists of two layers: the epidermis and the dermis. The epidermis is the outer layer that you see. This is where all the fun stuff happens: body art, sunburns, acne, etc. In fact, most skin problems occur in this layer. The dermis is underneath and makes up only 5-10 percent of your total skin thickness. It contains blood vessels, nerves and sensory receptors as well as sweat glands and hair follicles.


Hair grows from tiny tubular structures called hair follicles. Each hair follicle contains a root which lies below the surface of the scalp and a shaft which extends to your skin’s surface. Hair has many functions, including temperature regulation and providing protection from UV rays. It also provides cushioning for your head and gives you an attractive appearance! But there are some people who have too much hair; they suffer from hypertrichosis or hirsutism. This can be treated with laser treatments, which destroy the

The integumentary system is the organ system that protects the body from various kinds of damage, such as loss of water or abrasion from outside. The system comprises the skin and its appendages (including hair, scales, feathers, hooves, and nails).

The integumentary system has a variety of functions; it may serve to waterproof, cushion, and protect the deeper tissues, excrete wastes, and regulate temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure and temperature. In most terrestrial vertebrates with significant exposure to sunlight, the integumentary system also provides for vitamin D synthesis. The skin is the largest organ of the body weighting anywhere between 5-10 pounds.

The skin has three layers:

1. Epidermis: made up of stratified squamous epithelium with an underlying basement membrane. It forms a protective barrier over the body’s surface.

2. Dermis: beneath the epidermis lies the dermis. It is made up of dense irregular connective tissue and cushions the body from stress and strain. Within it are structures including sweat glands, blood vessels (including capillaries), nerves, hair follicles and muscles (arrector pili

The integumentary system is the largest organ system in the body. It consists of skin, hair and nails. This system functions to protect, regulate body temperature and excrete waste products. The integumentary system has many more functions than just being a protective shield against environmental threats.

The integumentary system aids in the regulation of body temperature by acting as a thermostat through contracting or expanding blood vessels just below the surface of the skin. The muscles of the skin are attached to hair follicles that when stimulated by cold or hot temperatures cause them to contract or expand. When these muscles contract, hairs stand erect and trap a layer of air against the skin which then causes the skin to feel warmer. On the other hand, when these muscles expand, hair lies flat and allows for better heat loss from skin which then causes the skin to feel cooler. In this way, it is easy to see how important this system is when it comes to keeping your body temperature regulated.

This system also plays a role in eliminating waste products from the body by producing sweat. Sweat glands are responsible for secreting sweat which is composed of water and salts. This secretion cools down the body when it evaporates from your skin.

In addition to protecting your body from

Your integumentary system, or skin, is the largest organ in your body. It protects you from infection, regulates your body temperature, and even helps you get rid of waste. Learn all about this important system and its components – including your nails and hair!

One of the most noticeable aspects of your skin is its color. The cells in the deepest layer of your skin have a lot to do with this. They contain a pigment called melanin that gives your skin its unique tone. The amount of melanin in your skin determines if it will be light or dark.

The epidermis is also home to Langerhans cells which are part of your immune system. These cells help protect you from foreign invaders such as bacteria, viruses and other pathogens.

In addition to protecting you against infection, the outermost layer of your epidermis serves as a barrier against the sun’s ultraviolet radiation (UVR). When exposed to UVR, melanin absorbs the rays and protects living cells deeper in the epidermis from damage.

The integumentary system is the first line of defense against invading organisms, dehydration, and UV radiation. The skin is the largest organ of this system. It is composed of a stratified squamous epithelium (epidermis), a thinner dermis, and a subcutaneous layer. The epidermis is composed of multiple layers that are constantly undergoing mitosis to replace the top layer as it sloughs off.

The epidermis contains keratinocytes that produce the protein keratin to make the skin waterproof. Melanocytes are present in the epidermis as well, and they produce melanin which colors the skin and protects against UV radiation. Other cell types include Merkel cells that touch sensory neurons, and Langerhans cells that act as antigen-presenting cells (APCs).

The dermis contains connective tissue with collagen and elastic fibers for strength and stretchability, respectively. It also contains blood vessels, sweat glands (eccrine and apocrine) which are associated with hair follicles, sebaceous glands that produce sebum for lubrication, sensory receptors for touch, temperature, pain, pressure, and itchiness (itch receptors), hair follicles with arrector pili muscles (which cause goose bumps),
