odour

Odour is the sensation we experience when tiny molecules released by substances, such as food or flowers, reach receptors in our nose. These molecules are volatile compounds that evaporate into the air and travel to our olfactory system. Our brain interprets the signals from these receptors, creating the perception of a smell. Different substances produce distinct odours based on their chemical makeup, which is why each scent is unique. Odour plays a crucial role in how we perceive and evaluate our environment, influencing feelings, memories, and even behavior.
