Human skin

find other alternatives, humans also have different body function then animals, and experiments can lead to animal extinction. First of all, there are many alternative that cosmetic companies can use. One of them is the Bovine Corneal Opacity and Permeability. This alternative uses cornea tissues in place of live rabbits. Also, Human cells and tissue culture have helped advance the studies in human disease. Epidermis is a human cell culture that has replaced animals in skin irritation test.…

people with a darker tone of skin, such as those of African American, Hispanic, and Asian descent. Also, it runs in families and is more common among the ages ten to twenty. Keloids are formed from the excessive healing of a wound. According to aafp.org, “After a skin injury, your cells try to repair the damage by forming a scar. This scar holds the wound together. In some people, the scar keeps forming long after the wound heals.” This can form from everyday skin injuries, such as piercings,…

Section A The skin is the largest organ of the human body. It's main function is to protect the internal organs, muscles, nerves, and blood vessels (Cancer Council Victoria, 2016). The skin is made up of three main layers - the epidermis, the dermis and the fat layer. The layer of fat insulates the body and keeps in warm from changing outside temperatures. The next layer is the dermis, which contains fat, collagen and elastin fibres which provide strength and flexibility to the skin. Blood…

It is composed of several hollow, interlocked keratin segments. Muscles in the tail contract causing the segments to vibrate against each other making the rattle which is then amplified because the segments are hollow. Every time a snake sheds its skin, a new rattle segment is added to its…

of the proteins that are found in skin and that regulate epidermal homeostasis. In order to discuss about the function of this protein, the role of skin should be overviewed first. Skin is the largest organ and has an important role in keeping the homeostasis of an organism. It consists of three layers: epidermis, dermis and subcutis. All these layers act together to maintain the integrity of a tissue and sustain the proper functioning of an organ. However, skin is a dynamic organ that…

A Brief Summary on Psoriasis Our skin is the largest organ of our body; it’s the entire human body outer cover and gives the body form and shape. It’s also separates the external parts of the body from the internal parts. Our skin protects our body against the light, heat, germs, cold temperatures, and injury. It’s protecting the body from chemical and mechanical substances. The skin is also the body immune system surveillance. The body produces tan of cells every day to replenish the dead…

organ system which protects the body from all external processes while still being able to be surrounded by the climate change on a day to day basis. The integumentary systems most important organ is the skin, which protects the body from external damage. Not only does the system consist of skin as its main organ but also has accessory organs as well, such as hair, nails, and exocrine glands. The hairs on our bodies gives the body insulation otherwise known as heat. The nails on our fingers and…

SUMMARY Natural skin care is the care of the skin by applying naturally-adopted ingredients mixed with naturally occurring carrier. Agents, preservatives, surface-active agents, humectant and emulsifiers. The classic interpretation of natural skin care is established on using botanically procured ingredients currently existing in nature or is cultivated by nature, without the use of fabricated chemicals, and assembled in such a way to preserve the integrity of the ingredients. Skin care has…

The Integumentary System Objective: Identify the skin structures on a model and name the layers of the skin. Also observe the degree of burns on a model. Materials: One skin structure 3-dimensional model One degrees of burn model Procedure: The model was observed for identification of the skin layers and its related structures. The second model was observed for the degrees of burn. Results: The layers of the human skin and the degrees of burn. Observation: The main purpose of…

Another alternative is using artificial human skin, such as “the commercially available products EpiDerm and ThinCert, is made from sheets of human skin cells grown in test tubes or plastic wells and can produce more useful results than testing chemicals on animal skin” (procon.org). Major arguments are the following: Is it ethical? Is it beneficial to scientist? Are there better alternatives? After…
