Explanation:

Our skin is the largest organ of our body, which has several functions like protecting us from the outside environment, maintaining body temperature, and helping us to feel the sensation of touch, pressure, heat, and cold. Among these functions, feeling is the most important one, which helps us to perceive the world around us. Therefore, the correct answer to the given question is option 'C', which says that our skin helps us to feel.

Functions of the skin:

There are several functions of the skin, which are as follows:

• Protection: The skin provides protection to our body from the outside environment by acting as a barrier against harmful substances, UV radiation, and microorganisms.


• Temperature regulation: The skin helps to regulate the body temperature by sweating, which cools down the body when it gets overheated.


• Sensation: The skin contains sensory receptors that help us to feel the sensation of touch, pressure, heat, and cold.


• Vitamin D synthesis: The skin helps to synthesize vitamin D when exposed to sunlight.


• Excretion: The skin excretes sweat, oil, and other waste products from the body.

The role of skin in feeling:

The skin contains sensory receptors called mechanoreceptors, thermoreceptors, and nociceptors, which help us to feel the sensation of touch, pressure, heat, and cold. These receptors are located in the dermis, a layer of the skin beneath the epidermis. When we touch something, the mechanoreceptors in the skin detect the pressure and send a signal to the brain. Similarly, when we feel heat or cold, the thermoreceptors in the skin detect the temperature and send a signal to the brain. The nociceptors are responsible for detecting pain, which alerts us to potential danger.

Conclusion:

The skin plays a crucial role in our daily lives by protecting us from the outside environment, regulating body temperature, synthesizing vitamin D, excreting waste products, and helping us to feel the sensation of touch, pressure, heat, and cold. Therefore, we should take good care of our skin by keeping it clean, moisturized, and protected from the sun to maintain its health and function.
