The human body has three main layers of skin: the epidermis, dermis, and hypodermis.
- Epidermis: This is the outermost layer of skin, responsible for protecting the body from the environment. It is made up of five sublayers: stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum.
- Dermis: This is the middle layer of skin, containing blood vessels, nerves, hair follicles, and sweat glands. It provides structural support and flexibility to the skin.
- Hypodermis: This is the innermost layer of skin, also known as subcutaneous fat. It acts as an insulator and helps to cushion the body.
While the skin is the largest organ of the body, it is important to note that the term "layers" can also refer to other structures within the human body, such as the layers of the heart, the layers of the eye, or the layers of the digestive system.
