if we inhale 100 amount of air and exhale 100 amount of air so why it is an active and passive process
Answers
Answer:
Human blood is designed to capture oxygen and safely bind it to a molecule known as hemoglobin. However, if you breathe in a high concentration of oxygen, it will overwhelm the blood, disrupting the central nervous system, damaging the lungs, heart and brain.
Explanation:
In respiratory physiology, the ventilation rate is the rate at which gas enters or leaves the lung. Ventilation is generally expressed as volume of air times a respiratory rate.
The volume of air can refer to tidal volume (the amount inhaled in an average breath) or something more specific, such as the volume of dead space in the airways. The three main types of ventilation rates used in respiratory physiology are:
Minute ventilation (VE): The amount of air entering the lungs per minute. It can be defined as
VE

Tidal Volume

Breaths Per Minute
Alveolar ventilation (VA): The amount of gas per unit of time that reaches the alveoli and becomes involved in gas exchange. It is defined as

Dead space ventilation (VD): The amount of air per unit of time that is not involved in gas exchange, such as the air that remains in the conducting zones. It is defined as
