We breathe air that is 21 percent oxygen, and we require oxygen to live. So you might think that breathing 100 percent oxygen would be good for us -- but actually it can be harmful. So, the short answer is, pure oxygen is generally bad, and sometimes toxic. To understand why, you need to go into some detail …
Your lungs are basically a long series of tubes that branch out from your nose and mouth (from trachea to bronchi to bronchioles) and end in little thin-walled air sacs called alveoli. Think of soap bubbles on the end of a straw, and you'll understand alveoli. Surrounding each alveolus are small, thin-walled blood vessels, called pulmonary capillaries. Between the capillaries and the alveolus is a thin wall (about 0.5 microns thick) through which various gases (oxygen, carbon dioxide, and nitrogen) pass.
When you inhale, the alveoli fill with this air. Because the oxygen concentration is high in the alveoli and low in the blood entering the pulmonary capillaries, oxygen diffuses from the air into the blood. Likewise, because the concentration of carbon dioxide is higher in the blood that's entering the capillaries than it is in the alveolar air, carbon dioxide passes from the blood to the alveoli. The nitrogen concentration in the blood and the alveolar air is about the same. The gases exchange across the alveolar wall and the air inside the alveoli becomes depleted of oxygen and rich in carbon dioxide. When you exhale, you breathe out this carbon dioxide enriched, oxygen-poor air.
Yes, exhaled air contains water vapor. When we breathe out, some of the water present in our bodies is expelled as vapor along with the carbon dioxide and other gases. The amount of water vapor in exhaled air can vary depending on factors like humidity and hydration levels.
The total amount of air that can be exhaled after maximal inhalation is called the vital capacity. It is often used as a measure of lung function and can be helpful in diagnosing respiratory disorders.
Earth's atmosphere has roughly a 0.04% of CO2 (by volume), that's about the percentage we inhale.
Chargaff's rule states that the amount of adenine in DNA is equal to the amount of thymine, and the amount of cytosine is equal to the amount of guanine. This principle underlies the complementary base pairing in DNA strands.

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.
Yes, exhaled air contains water vapor. When we breathe out, some of the water present in our bodies is expelled as vapor along with the carbon dioxide and other gases. The amount of water vapor in exhaled air can vary depending on factors like humidity and hydration levels.
Exhaled air, which has a slightly higher amount of carbon dioxide, is heavier than inhaled air.
The amount of air that can be exhaled after the deepest inhalation is called the vital capacity. It represents the maximum amount of air a person can breathe in and out of their lungs during a single breath.

exhaled water vapor will be greater than inhaled water vapor
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.
Too much of it can cause you to suffocate, however we take in a good amount of it every time we take a breath. inhaled air contains about 0.5 percent of co2 but exhaled air contains 4%-5% of co2
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.
There is 97.5 percent zinc in a penny and 2.5 percent copper
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.
