Sentences with phrase «olfactory system»
The phrase "olfactory system" refers to the part of our body that helps us smell things. It includes our nose, where we have special cells called olfactory receptors that detect different scents. These scents then travel to our brain, which helps us recognize and understand what we are smelling. Full definition
