"Inspired air " is the stuff around us, so
O2 is about 20% & CO2 is about .003 % ...
and why? is because of plants and chlorophyll.

Is cold air heavier than warm air?
False because warm air rises. The particles in cold air are moving more slowly and make cold air more dense than warm air.
What is heavier and absorbs more heat than air?
what is it
Which is more dense air that is 90 degrees or air that is 40 degrees?
Colder air is denser than warmer air
What diagram show the path taken by oxygen from the air inspired air passing to the blood?
Trachea bronchus bronchiole alveoli haemoglobin
Who discovered that air was more than empty space?
Who discovered that air was more than just empty space Joseph Priestly spelled Joseph Priestley to whoever was the idiot who gave the incorrectly spelled first answer
Is Pco2 is greater in the alveoli than it is in the arterial end of pulmonary capillaries?
No. Once blood reaches the alveoli it will immediately start to release CO2 to the air in our lungs and absorb O2 from the air in our lungs. This means that the PCO2 will be higher in the blood of the pulmonary artery than in the blood of the alveolus. If this were not so, then passing blood through the alveoli would be pointless.
How does expired air differ from inspired air?
Both Inspired and expired air have higher amounts of oxygen than Carbon Dioxide. Inspired air has higher amounts of oxygen than expired, while expired air has higher amounts of Carbon Dioxide than inspired air.
What is pco2 in atmosphere?
The pCO2 is the partial pressure of carbon dioxide in blood moving through the arteries of the human body. While it can be impacted by a high carbon dioxide concentration in the air being breathered, it is not a thing that is measured in connection with the atmosphere.Normal values o pCO2 in arterial blood are considered to be 35 - 45 mmHg.
What gas is more abundant in exhaled air than inhaled air?
Nitrogen is the most abundant gas in the atmosphere ( ~ 80% ) and therefore is the dominant species in both inspired as well as expired air.
Why CO2 is more in alveolar air than expired air?
Alveolar air mixes with air in the anatomic dead space on its way, which is rich in oxygen. hence % of oxygen is more in expired air. Thus though amount of CO2 does not decrease, percentage decreases as inspired air contains very less amount of CO2 (0.03%).
What is cold air more than warm air?
Cold air is more dense than warm air.
Why does expired air contain more carbon dioxide than inspired air?
I did not quite get this, but if this helps, good. ( this is from my biology book)"Carbon dioxide is made by cells as a waste product of respiration, and is released across the gaseous exchange surface"
Is lead more dense than air?
Lead is more dense than air.
Which primary bronchus for an inspired object to become lodged?
The right primary bronchus is more likely to have an inspired object become lodged in itself because it is more wide than the left primary bronchus and is also located at a steeper angle. It is more wide because the right lung is larger and needs a wider bronchus for air to fill it up.
Why does water exert more pressure than air?
Water is more dense than air is.
Why is air more buoyant than water?
Air is more buoyant than water because air is less dense than water, and everything the thing that is less dense is always more buoyant than what is more dense than it.
What does cold air have more than hot air?
Cold air is more dense than hot air. This is because gas expands when it is heated.
