Explanation:
The primary functions of the skin in the human body are manifold, but the key roles can be distilled into five main categories. These include acting as a protective covering, operating as a sensory organ, serving as a temperature regulator, functioning as part of the excretory system, and allowing absorption.
As a protective covering, the skin defends the body against physical damage, bacterial invasion, and other harmful environmental factors. As a sensory organ, it provides us with the vital ability to feel and respond to touch, heat, cold, pressure, and pain. Its role as a temperature regulator ensures we maintain a steady, safe body temperature, adjusting to both internal and external conditions by sweating or goosebumps. In its function as an excretory system component, it helps to remove waste materials like urea and salt through sweat. Additionally, it allows the absorption of certain substances, such as topical medications.
