The skin consists of two layers and a closely associated layer. View this animation (http://openstaxcollege.org/l/layers) to learn more about layers of the skin. What are the basic functions of each of these layers?
To write:
The different layers composing the skin.
Introduction:
The skin is composed of the three main layers, namely the epidermis, the dermis, and the hypodermis. The epidermis is the outermost layer while the dermis is present just below the epidermis. The hypodermis is the deepest layer of the skin.
Explanation of Solution
The epidermis, which is the outermost layer of the skin, functions as a waterproof barrier. It protects the tissue lying beneath it from infection, chemicals, dehydration and any kind of mechanical stress.
The dermis is present just beneath the epidermis. It is composed of tough connective tissue and include different types of the glands and the cells. The blood vessels in this layer provide nourishment to the tissues.
The hypodermis layer is made up of the connective tissue and fat. It functions by attaching the dermis to the muscles and the bones. Moreover, this layer stores fat as an energy reserve.
The skin is made up of three layers, namely the epidermis, the dermis and the hypodermis. The epidermis act as the protective layer. The dermis contains the blood vessels, and the hypodermis contains the fat.

- Species Interactions Explain how predators, prey and scavengers interact. Explain whether predators and scavengers are necessary or beneficial for an ecosystem.arrow_forwardmagine that you are conducting research on fruit type and seed dispersal. You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different. (Editor’s note: Providing this information in your discussion will help readers to consider the significance of the research).arrow_forwardWhat is the difference between Uniporters, Symporters and Antiporters?
