Detailed explanation-1: -The temperature of a healthy human being is about 37 degrees Celsius while the exhaled breath temperature varies around 34 degrees Celsius. That means that a difference of about 3 degrees Celsius was found between the air temperature from alveoli and the breath exhaled temperature.
Detailed explanation-2: -The conducted studies, which are reported in the literature, are age-biased. Paredi et al. [25] showed that exhaled breath temperature (EBT) for normal participants is 34.45 °C on average, and 35.75 °C for asthmatic participants.
Detailed explanation-3: -Exhaled air usually is warmer than ambient temperature. Air in the lungs is warmed by core body heat, thereby creating a temperature difference between air entering and exiting the respiratory system.
Detailed explanation-4: -They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation).
Detailed explanation-5: -In turn, exhaled air contains: nitrogen – 78% oxygen – 17% carbon dioxide – 4%
