What is the structure and function of the skin?
Have you ever wondered what is our body’s largest organ?
Could it be heart? What about your lungs ? or your brain?
No, they are not nearly the body’s largest organ?
You can see your body’s largest organ right now?
What are we talking about?
The skin of course!!
The skin is the largest organ of the body, accounting for about 15% of the total adult body weight.
It performs many vital functions, including protection against external physical, chemical, and biological ****ailants, as well as prevention of excess water loss from the body and a role in thermoregulation.
The skin is continuous, with the mucous membranes lining the body’s surface.
The integumentary system is formed by the skin and its derivative structures.
The skin has basically three layers - Epidermis, dermis and hypodermis.
The epidermis is the outermost layer of skin which provides a waterproof barrier and creates our skin tone.
The epidermis consists of a specific group of cells known as keratinocytes which function to synthesize, keratin which is a long thread-like protein with a protective role.
The dermis is beneath the epidermis and it contains tough connective tissue, hair follicles, and sweat glands.
The dermis is fundamentally made up of the fibrillar a structural protein is known as collagen.
The dermis lies on subcutaneous tissue or panniculus, which contain small lobe of fat cells known as lipocyte.
The deeper subcutaneous tissue or hypodermis is made of fat and connective tissue.
The color of the skin is created by special cells called melanocytes, which produce the pigment melanin.
Melanocytes are located in the epidermis.
