Скачать или смотреть How Many Scents Can a Human Detect?

The human nose is capable of detecting a vast array of scents, with estimates ranging from 10,000 to 100,000 different odors. This impressive feat is due to the millions of olfactory receptors in the nose that can distinguish between various volatile molecules. However, compared to dogs, humans have a relatively limited sense of smell. Dogs have approximately 300 million olfactory receptors, which allows them to detect scents that are imperceptible to humans. Dogs are commonly used for tasks such as tracking, detecting explosives, and identifying diseases, demonstrating their superior olfactory capabilities. Overall, while the human nose is still a remarkable sensory organ, dogs have a much more acute sense of smell.
