Integumentary System (skin)

There are 46 chromosomes in a human skin cell.

The dermis is the layer of skin that contains only living cells. The epidermis contains both living and dead cells.

Garlic affects your body odor. When you sweat it will smell pretty bad.

Sudoriferous glands are also known as sweat glands.

It mite be hereditary i have the same problem but on my finger go to the doctors they will help but its not a big of a deal.

Skin constantly needs to renew itself to maintain its protective barrier against environmental threats, such as pathogens and UV radiation. This renewal process helps to replace dead or damaged cells, ensuring optimal functionality and appearance. Additionally, as we age, skin regeneration slows down, making regular renewal essential for skin health and resilience. Overall, continuous renewal supports healing and adaptation to external factors.

Thick skin found on the palms of the hands and the soles of the feet have no sebaceous glands. The glands are found with hair follicles.

true! Sebaceous glands, that produce this waxy oily secretion called SEBUM which lubricates the hair shaft and inhibits bactirial growth withing the surrounding area.

The stratum lucidum, which is present in the thick skin of the palms and soles, is absent in thin skin

You have the immune system to protect you from the infectious diseases. You have two types of immunity. Cell mediated and humeral type.

The skin tissue is the main controller of our body temperature, it also protects our cells from undergoing osmosis when we swim and it also protects our innards from infections and collisions.

The skin gathers information about the environment. To understand how the skin does this, place your fingertips on the skin of your arm and press down firmly. Then lightly pinch yourself. You have just tested some of the nerves in your skin. The nerves in skin provide information about such things as pressure, pain & temperature. Pain messages are important because they warn you something in your surroundings may have injured you.

The skin is made up of skin cells and glanes. Glanes are little holes every where on your body that make you sweat. So the skin cells are made from genes. When your dad has Sex with your mom he puts his penis in her and goes in and out her hard in the VAJ

Skin has Melanin which is brown-colored pigment, which protects the skin from the harmful UV rays that come from the sun. When the UV rays hit the skin the skin turns darker in order to protect or shield it. Tanning or darkening of the skin is in reaction to the harmful UV given off by the sun. Consider how in warm or tropical locations such Africa, Asia, and South America people have darker pigmented skin. It is in order to protect and shield it from damage. In other words, the sun is harmful to the skin---dark or fair. When your skin tans it is in order to protect it from even more damage.

The Digestive System extracts nutrients that are carried into the bloodstream and sent to the other systems. the integumentary system is one of the systems. The integumentary system synthesizes vitamin D in the presence of UV radiation; vitamin D helps the digestive system absorb calcium.

No, skin protects us from all things sun, dirt, etc. especially infections! Viruses and bacteria would be able to infect us much more easily because they would have direct access to our tissues.

Keratin plays a crucial role in the epidermis, which is the outermost layer of the skin. The epidermis serves as a protective barrier, preventing the loss of moisture and protecting the body from external elements, such as microorganisms, chemicals, and physical trauma. Keratin is a fibrous protein that contributes to the structural integrity and protective functions of the epidermis in the following ways:

1. **Formation of the Epidermal Barrier:** Keratinocytes, the primary cells of the epidermis, produce and accumulate keratin as they move from the deeper layers of the epidermis to the surface. As keratinocytes mature and fill with keratin, they become flattened and tightly packed, forming a tough and resilient barrier.

2. **Waterproofing:** Keratin is hydrophobic, meaning it repels water. The accumulation of keratin in the outer layers of the epidermis helps to create a waterproof barrier, preventing excessive water loss from the body and minimizing the absorption of water from the external environment.

3. **Protection from External Threats:** The tough, keratin-rich outer layer of the epidermis acts as a shield against harmful microorganisms, UV radiation, chemicals, and mechanical injuries. It helps to reduce the risk of infections, irritations, and damage to the underlying layers of the skin.

4. **Resistance to Wear and Tear:** Keratin is highly resistant to mechanical stress and abrasion. It provides strength and durability to the skin, allowing it to withstand everyday wear and tear.

5. **Hair and Nail Structure:** Apart from the epidermis, keratin is also a major component of hair and nails. In hair, keratin provides strength and elasticity, while in nails, it contributes to their hardness and protective function.

In summary, keratin is essential for maintaining the integrity and protective properties of the epidermis. It helps create a strong, waterproof barrier that shields the body from external threats and maintains proper hydration and homeostasis. Additionally, keratin is a key structural component of hair and nails, contributing to their strength and resilience.
