A cigarette is a small cylinder of finely cut tobacco leaves rolled in thin paper for smoking. The cigarette is ignited at one end causing the cigarette to smoulder and allowing smoke to be inhaled from the other end, which is held in or to the mouth; in some cases, a cigarette holder may be used, as well.
The breathing rate, or the number of times that a person breathes in and out in 1 minute, is often checked by health care professionals to determine the health of a person. The normal breathing rate is between 12 and 18 breaths per minute.
The respiratory rate which is the number of breaths a person taken in one minute is fixed at an average of around 12 every minute for adults. Any increase in temperature causes a rise in the quantity of oxygen that is liberated by the presence of hemoglobin in the blood.
