English Vocabulary: All About the Five Senses243

The five senses are a gift that allows us to experience and interact with the world around us. They are vision, hearing, smell, taste, and touch. Each sense is unique and provides us with different information about our surroundings.

Vision

Vision is the ability to see. It is the most important sense for humans, and it allows us to perceive the world around us. The eyes are the organs of vision, and they work together to create a picture of the world that we can see. The eyes are sensitive to light, and they convert light into electrical signals that are sent to the brain. The brain then interprets these signals and creates a visual image of the world.
