Skin. It is the largest organ on the human body. It creates a protective layer against heat, light, the environment, injury, and infection. It helps regulate the body’s temperature; stores water, fat and Vitamin D; prevents entry of bacteria; and acts as a sensory organ. And Dr Abhijeet Kumar Jha is the best skin specialist in Patna who gives you the best result on your skin.
There are three layers of skin:
Epidermis- This is the outer most layer that sloughs off dead skin cells and acts as a protective barrier against foreign bodies, infections, and the sun. The epidermis also contains melanocyte cells, which are responsible for skin pigmentation.
Dermis- The middle layer of skin, the dermis houses hair follicles, sebaceous (oil) glands, sweat glands, capillaries (small blood vessels), and lymph vessels. It is held together by a protein called collagen. Sweat glands are part of the body’s cooling system. The dermis also contains touch and pain receptors.
Subcutaneous- This is the deepest layer of skin, containing larger blood vessels and nerves. It is made up of a network of collagen and fat cells, and plays an important role in the manufacture of Vitamin D, protecting against injury, and conserving body heat.
