skin
Skin is the body's largest organ and serves as a protective barrier between internal organs and the external environment. It regulates temperature, prevents water loss, and helps protect against infections. Skin is made up of three main layers: the epidermis (outer layer), dermis (middle layer), and hypodermis (innermost layer). The skin also contains hair follicles, sweat glands, and sensory receptors that allow us to feel touch, pain, and temperature. Additionally, it plays a role in the production of vitamin D when exposed to sunlight. Proper skin care is essential for maintaining its health and functionality.

Skin is the body's largest organ, serving as a protective barrier between the internal organs and the external environment. It has several layers, including the epidermis (outer layer), dermis (middle layer with blood vessels and nerves), and subcutaneous tissue (inner layer for insulation and cushioning). Skin regulates temperature, prevents water loss, and provides sensory information through touch, heat, and pain. It also plays a role in producing vitamin D when exposed to sunlight. Maintaining healthy skin is important for overall well-being, as it reflects our health and can provide insights into underlying medical conditions.
