Body surface

Body Surface is the external covering of the human body, also known as the skin. It is the largest organ of the integumentary system, and its primary function is to act as a barrier against the external environment.

Structure

The body surface is composed of two main layers: the epidermis and the dermis. The epidermis is the outermost layer, which provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.

Functions

The body surface has several key functions. It protects the body from external threats such as pathogens and harmful substances. It also helps regulate body temperature through sweat and hair, and allows the sensation of touch, heat, and cold.

Health and Disease

Various diseases and conditions can affect the body surface, including dermatitis, psoriasis, and skin cancer. These conditions can cause symptoms such as redness, itching, and pain. Treatment options vary depending on the specific condition and may include topical medications, systemic treatments, and surgical interventions.
