define vital capacity and a normal amount

the maximal expiration following maximal inspiration, a normal amount is 1.5 L

what do chemoreceptors do and where are they located

they monitor co2, o2 and ph. its in the medulla

where are peripheral chemoreceptors

aortic arch and carotid sinus

what is ventilation and whats is measured by

breathing in and out and is measured by a spirogram

what factors might account for the difference/similarity bw genders

sex, size/height, age, cardiovascular shape

what is the average breaths per min

12-20 or 15 on average

what is tidal volume (TV) and the average amount for each gender

the amount of air taken in or expelled out of lungs during each quiet breathe. for men and women: 500 ml

what is inspiratory reserve volume (IRV) and the average amount for each gender

the amount of air taken into lungs during a forced inspiration following a quiet inspiration; irv is a measure of lung compliance. an average for men is 3100 ml and for women its 1900

what is expiratory reserve volume (ERV) and the average amount for each gender

the amount of air expelled from lungs during a forced exipration following a quiet expiration; erv is a measure of lung and chest elasticity. the average male is 1200 ml and women is 700ml

what is residual volume and the average amount for each gender

the amount of air left in lungs following a forced expiration. average male is 1200 ml and women 1100ml

what is inspiratory capacity, the formula and the average amount for each gender

the total ability to inspire. tv + irv. men is 3600ml and 2400ml

what is functional residual capacity, the formula and the average amount for each gender

the amount of air typically left in lungs after you expire quietly. erv + rv. men is 2400ml and women is 1800ml

what is vital capacity, the formula and the average amount for each gender

the maximum amount of air that can be forcefully expired after a forced inspiration. tv + irv + erv. men is 4800ml and 3100ml

what is total lung capacity, the formula and the average amount for each gender

the maximum amount of air the lungs can hold. tv + irv +erv + rv. men is 6000ml and women is 4200ml
