However, if you breathe in a high concentration of oxygen, it will overwhelm the blood, disrupting the central nervous system, damaging the lungs, heart and brain. How much oxygen do we inhale and exhale? The average human being inhales and exhales a total of 11,000 liters of air per ...
Divers could also experience pulmonary edema, where fluid collects in the lungs’ air sacs, or decompression sickness, when the oversaturated gasses in the body form bubbles in the blood on a diver’s ascent, says Lindholm, who studies these problems. Divers could also blackout when they reach...
As the blood goes through the lungs, some of the alcohol moves across the membranes of the lung's air sacs (alveoli) into the air, because alcohol will evaporate from a solution — that is, it is volatile. The concentration of the alcohol in the alveolar air is related to the ...

While most lung cells are resistant to becoming cancerous by Myc, neuroendocrine cells, are very sensitive to the oncogenic effects of Myc. Conversely, epithelial cells, which line the air sacs of the lungs and are the precursors to lung adenocarcinomas, grow excessively in response to mutated ...

The human sense of smell is the first of the senses to develop after birth. This sense is at its peak when we are in our late teens, and from there, it lessens with age. During the spring and summer in many areas, there is more moisture in the air, which enhances the sense of sm...
When you take in air, your diaphragm -- a muscle in your chest that helps you breathe -- moves downward. This drops the pressure in the tubes and sacs in your lungs and draws air into them. If you have a condition like sleep apnea, there may be times (like while you’re sleeping)...

constricting blood vessels; it also stimulates the production of dopamine, a neurotransmitter that controls the brain's pleasure center. Inhaling nicotine gives the most immediate effects, and that's not a coincidence; it's because your lungs are lined with millions of tiny air sacs called ...
