Smell (Olfaction)

Olfaction, or sense of smell, is the process by which your brain detects and identifies airborne molecules. When you smell something, tiny particles from that object enter your nose and reach specialized sensory cells called olfactory receptors located in the nasal cavity. These receptors send electrical signals to your brain, which interprets them as specific odors. Smell is closely linked to taste and memory, playing a key role in enjoying food and detecting hazards like smoke or spoiled food. It is a complex and vital sense that helps you understand and navigate your environment.
