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.
Normal Respiratory Rate â Respiration-Breathing Frequency. Respiratory rate (respiration rate, breathing frequency, breathing rate, ventilation rate, pulmonary ventilation rate, and respiratory frequency) is the number of breaths that a person takes during one minute.edical textbooks suggest that the normal respiratory rate for adults at rest is only 10-12 breaths per minute. Older physiology textbooks often provide even smaller values (e.g., 8-10 breaths per minute), while more recent textbooks can give up to 15-18 breaths per minute.
