vital

 [vi´tal]
pertaining to life; necessary to life.
vital capacity (VC) the greatest volume of gas that, following maximum inhalation, can be expelled during a complete, slow, forced exhalation; equal to inspiratory capacity plus expiratory reserve volume.



Forced vital capacity (FVC) is the greatest volume of air that can be expelled when a person performs a rapid, forced exhalation, which usually takes about five seconds. The greatest volume of air a person can exhale during one, two, three, or more seconds of forced exhalation is called the forced expiratory volume (FEV). A subscript is added to the abbreviation FEV to indicate the phase during which the particular amount or volume of air is exhaled. A volume exhaled during the first second is designated FEV1.0, a volume exhaled during the first two seconds is designated FEV2.0, and so on. The rate at which a specified volume of air is exhaled during a forced exhalation is called forced expiratory flow (FEF). The rate at which air is exhaled from a forced expiratory volume of 200 mL to one of 1200 mL is designated FEF200–1200 (formerly called maximal expiratory flow, MEF); the rate from 25 to 75 per cent of the forced vital capacity is designated FEF25–75% (formerly called maximal midexpiratory flow, MMF).

Laboratory values for vital capacity, forced vital capacity, forced expiratory volume, and forced expiratory flow are usually reported both as absolute values and as statistically derived predicted values based on the age, sex, and height of a patient. The statistical value is reported as a percentage. See also pulmonary function tests.

Q. I was shocked to note that genes play a vital role in building muscles Is this possible? I am , 20 years old. I am always dreaming to build muscle like my favorite hero who maintains 8 abs. Anybody can dream but to live that dream is a difficult task. Out of curiosity, I had discussed my desire to build muscles with my friends. But I was shocked to note that genes play a vital role in building muscles. My family doesn’t have a history of muscles and this fact has put me in to a difficult situation. Is this possible…If so, how can I live my dream? If the family doesn’t have a history of muscle growth, then what happens to the generation which follows them? I need a positive feedback to my query……

A. there's a genetic potential for fitness, like there is a genetic connection and potential for inelegance. but no matter how smart are your parents- if you won't study you won't live that potential, and some one who doesn't have that genetic ability and will study- will be better. the same thing with physical fitness.
