The Short Answer
It's usually not noticeable unless you sniff harshly, but one nostril is usually more open and free-flowing than the other. The nostril that's closed usually swaps back and forth after several hours throughout the day. When a nostril is more closed, it's swollen, because the blood vessels inside the nose are swollen. During that time, your immune system attacks all the nasty stuff that came into your nose. It's harder to breathe when that happens. But your other nostril is wide open and maximum air comes in. This combination of having one closed nostril and one open nostril is a super efficient way for your body to both clean the nasties and breathe full air at the same time. If it was all just 1 nostril, then every few hours you would have difficulty breathing. Air breathed through the nostrils are combined in the back and flow into both longs. One nostril does not lead into one lung.
