dead space
dead space is air that is inhaled by the body in breathing, but does not take part in gas exchange. Not all the air in each breath is able to be used for the exchange of oxygen and carbon dioxide. About a third of every resting breath is exhaled exactly as it came into the body. In adults, it is usually in the range of 150 mL.1 Because of dead space, taking deep breaths more slowly (e.g. ten 500 mL breaths per minute) is more effective than taking shallow breaths quickly (e.g. twenty 250 mL breaths per minute). Although the amount of gas per minute is the same (5 L/min), a large proportion of the shallow breaths is dead space, and does not allow oxygen to get into the blood.
The Urban Dictionary Tee
used it as a cum rag
Great fit and soft material. Gave as gift. Big hit!
Great conversation piece! Plus I can never find anything with my name on it. This was a great find! Will definitely order more!!!!
Got exactly what I wanted.
Exactly what I expected, thanks!
I don't visit Urban Dictionary alit so I only recently saw they offered merch. I immediately started looking up words for potential Christmas gifts. Found the ideal gift for my brother & ordered a shirt. It arrived very quickly and I love it. It's exactly as pictured on the site and being able to customize it with his name makes it perfect. I only hope he loves it as much as I do. Will definitely keep Urban Dictionary in mind when I need to find a great gift.
