Week 7 – Discussion Board 1

[Art Liebl]

In at least 250 words talk about the  layers of skin and function of each one initial post due by Thursday Respond to two fellow students by Monday.

The skin is the largest organ in the human body and is made up of three main layers: the epidermis, the dermis, and the hypodermis, also called the subcutaneous layer. Each layer has an important job that helps protect the body and keep it healthy. The outer layer is the epidermis. This is the part of the skin that we can see. Its main function is to protect the body from germs, bacteria, harmful chemicals, and the sun’s ultraviolet (UV) rays. The epidermis also helps prevent the body from losing too much water. New skin cells are constantly made in this layer, and older cells are pushed to the surface where they eventually fall off.The second layer is the dermis, which is thicker than the epidermis. The dermis contains blood vessels, nerves, hair follicles, sweat glands, and oil glands. This layer gives the skin its strength and flexibility because it contains collagen and elastin fibers. The blood vessels in the dermis help regulate body temperature by bringing heat closer to or farther from the surface of the skin. The sweat glands also help cool the body by producing sweat. The nerve endings allow us to feel pain, pressure, touch, and temperature.The deepest layer is the hypodermis, also known as the subcutaneous layer. This layer is mostly made of fat and connective tissue. Its main function is to store energy, provide insulation to help keep the body warm, and cushion the muscles and bones from injury. It also helps attach the skin to the muscles and other tissues underneath. Together, these three layers work as a team to protect the body, regulate body temperature, store energy, provide sensation, and help keep us healthy. Without these layers working together, the body would be much more vulnerable to injury, infection, and changes in temperature.

As already mentioned, the skin is the largest organ of the body, the role of the skin is protecting us everyday. The skin is made of different layers and each on has their own funtion. These layers are: epidermis, the dermis and the hypodermis, which is also called the subcutaneous layer.
The part of the skin that we can see, which is the outer laye, is the epidermis. Its main job is to act like the barrier between the body and the outside enviroment. It also helps the body keep water inside, so we do not lose too mucho moisture. Also it is important to know that this layer is constatly making new skin cells; the old cells move to the surface and fall off naturally.
The second layer is the dermis, this layer is under the epidermis and is thicker. This layer constains blood vassels, nerves, sweat glands, oil glands and hair follicles.
The deepest layer is the hypodermis, this one is made of fat and connective tissue, its job is to store energy, protect the body from injury, and help keelp the body warm. Also is important to know that this layer of the skin connects the skin to the muscles and tissues under it. In conclusion, we have three layer of the skin that work together that protect our body, controls temperature and helps the body´s health.

The skin is made up of three main layers; the epidermis, the dermis, and the hypodermis. Each layer has its own job and together they help keep the body healthy and functioning properly. The epidermis is the outermost layer of the skin and is the body’s first line of defense against bacteria, viruses, and any unwanted objects in the body. The epidermis is constantly making new skin cells while old, dead cells naturally shed from the surface. It also contains melanin which is the pigment that gives skin its color and helps protect it from sun damage.
The dermis is the middle layer and it is much thicker than the epidermis. It contains blood vessels, nerves, and sweat glands. The dermis provides strength and flexibility to the skin and also helps regulate body temperature by producing sweat. There are also many nerve endings in this layer allow us to feel sensations such as touch, pressure, heat, cold, and pain.
The hypodermis is the third and deepest layer of the skin which is made mostly of fat and tissue. In addition it connects the skin to the muscles and other tissues underneath, allowing the skin to move without tearing. Overall each layer of the skin has a unique function but they all work together to protect our body otherwise our bodies would be much more vulnerable to external dangers.
