Skin
The skin is the outer covering of mammals and some other animals. It has many important jobs. First, it helps protect the body by stopping pathogens such as bacteria and parasites from getting inside. Second, it helps control the body's temperature. It does this by allowing evaporation from the skin and by making changes to help the body stay at the right temperature. The skin is a physical barrier. In some animals it is very strong, while in humans it is less protective. The skin and hair of mammals also have several uses. Besides temperature regulation and protection, some hair is used to send signals to other animals.
Most animals have extra protection on their skin. Mammals have hair or fur. Birds have feathers. Most fish and reptiles, such as snakes and lizards, have scales.[1]
The skin is the largest organ in the human body. Without skin, people would easily get infections and diseases. As part of the immune system, the skin can also help show signs of some diseases.[2] Keeping the skin clean is important for good health. All mammals clean and care for their hair and skin. Skin care is an important part of staying healthy.
Humans can have different skin colours, such as black people and white people. These differences happen because of how their genes have adapted to different environments and climates over many generations. Humans can also have different skin types. The main skin types are oily, dry, combination, and sensitive.
A simple way to understand your skin type is to wash your face with a gentle cleanser and leave it without any skin care products for about one hour. If your skin feels tight and dry, you may have dry skin. If your forehead, nose, and chin (called the T-zone) become oily while the rest of your face stays fairly dry, you may have combination skin. If your face becomes red, irritated, itchy, or flaky, you may have sensitive skin.[3]
The skin also helps protect the body by blocking harmful bacteria and viruses. It helps reduce the harmful effects of UV rays from the Sun. The skin also helps control body temperature.
Animal skins can be made into leather. Leather is used to make many things, including shoes, bags, and balls.
