spirometer
Inhaled air contains a greater volume of oxygen than carbon dioxide. Exhaled air is the opposite, since after the exchange of gases in the lungs the carbon dioxide in the blood is transferred into the lungs. Exhaled air contains a greater volume of carbon dioxide than oxygen. Also, there is more water vapour in exhaled air than inhaled air.
One common test to measure lung ventilation mechanics is spirometry. This test involves measuring the amount and speed of air that can be inhaled and exhaled from the lungs. It helps evaluate conditions such as asthma, chronic obstructive pulmonary disease (COPD), and restrictive lung diseases.
The amount of air that can be exhaled after the deepest inhalation is called the vital capacity. It is the maximum amount of air a person can exhale after taking the deepest breath possible. It is an important measure of lung function.
The composition of expired air in humans is usually: 17 % oxygen, 3. 5 % carbon dioxide, 79 % nitrogen, and temperature range of between 29 and 34 degrees Celsius, Moisture is usually a component of the expired air as well.
Tidal volume is defined as the amount of air inhaled or exhaled during a single breath at rest. It is an important component of lung function and is typically measured in milliliters. In healthy adults, the average tidal volume is about 500 milliliters per breath. This measure helps assess respiratory health and efficiency in gas exchange within the lungs.
exhaled water vapor will be greater than inhaled water vapor
Exhaled air, which has a slightly higher amount of carbon dioxide, is heavier than inhaled air.
Biological value
One measure of lung size is called vital capacity and it refers to the amount of air that can be inhaled and exhaled forcibly in one breath.
Nitrogen is not used by the body; oxygen is taken in and carbon dioxide and water goes out.
Inhaled air contains a greater volume of oxygen than carbon dioxide. Exhaled air is the opposite, since after the exchange of gases in the lungs the carbon dioxide in the blood is transferred into the lungs. Exhaled air contains a greater volume of carbon dioxide than oxygen. Also, there is more water vapour in exhaled air than inhaled air.
The amount of carbon dioxide exhaled is always greater than the amount inhaled because part of the oxygen inhaled is converted into carbon dioxide by metabolic processes of digestion, while any carbon dioxide inhaled remains unchanged in the body and is always exhaled again.
Approximately 16% to 17% of inhaled oxygen is exhaled during normal breathing. The exhaled air still contains a significant amount of oxygen, as our bodies only use a small portion of the oxygen we breathe in for cellular respiration.

Amount of air that is inhaled or exhaled with normal breath. NORMAL VALUE IS 500ml Vital capacity= IRV+ TV+ ERV TV = Vital capacity- (IRV+ERV) I hope, this is it!!
