no because some people think another gas is important
Yes, oxygen is the most important gas in the air for humans as it is essential for cellular respiration, which provides cells with the energy they need to function. Without oxygen, humans would not be able to survive.

Yes, bromine gas is heavier than air. It is about 7 times denser than air, so it will tend to sink and accumulate in low-lying areas. This makes it important to handle bromine gas with caution to avoid inhalation.
no. Cows make Methane gas (poop) which is a greenhouse gas. However dirty,stinky humans are the major causes of air pollution.
carbon-monoxide
Oxygen is the only gas used by humans for respiration.
The three phases of breathing are:The Active phase which is known as (inhalation/ inspiration).Phase 2. gas exchange in the lungs also known as (Internal exchange).The Passive phase which is known as (exhalation /expiration).
Humans take oxygen from the air and absorb it into the blood through the process of respiration.
