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.
Why there is less oxygen in expired that in inspired air?
During inhalation of air, oxygen is taken up by the body for use in cellular respiration. During exhalation, the body releases carbon dioxide as a waste product, lowering the overall oxygen content in the exhaled air. Additionally, the body only extracts a portion of the oxygen in each breath, so the air exhaled contains less oxygen than the air inhaled.
Water content of expired air is less than inspired air?
Yes, the expired air has a lower water content compared to inspired air due to moisture being extracted from the air during gas exchange in the lungs. This process helps to humidify the inspired air and prevent the respiratory system from becoming too dry.
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%).
Why percentage of nitrogen in inspired and expired air different?
Nitrogen is an inert gas; that is it is not metobolised or produced by the body. In that case, the molar quantity inhaled must equal the molar quantity exhaled over a period of time. We can write this as VI x FI = VE x FE (where VI and VE are the inspired and expired volumes breathed over that time period, and FI and FE are the concentrations of N2 in the inspired and expired gas respectively). However, the terms VI and VE are not equal because we generally consume more oxygen than we produce CO2 (i.e. our respiratory quotient is not 1), so we exhale a smidgin less gas than we inhale. So if VI does not equal VE, it follows that FI cannot equal FE.
An oxygen deficient atmosphere has an oxygen concentration less than?
An oxygen deficient atmosphere has an oxygen concentration less than the normal level of around 21%.
How does density of helium compare to density of oxygen and nitrogen?
Helium is lighter (less dense) than oxygen & nitrogen.
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"
Do lipids contain less oxygen than carbohydrates?
Yes Lipids contain less oxygen because the ratio of hydrogen to oxygen for carbohydrates is 2:1 while for lipids it varies but let's say its for Lauric acid (CH3C10H20COOH) the ratio is 12 hydrogen for 1 oxygen. So lipids do contain less oxygen than carbohydrates
How much is an expired tag ticket in Michigan?
$100.00 for less than 3 days $120.00 for over 3 days
Can you still use tapioca granules after it is expired?
Probably, as long as they look fresh and are less than 6 months out of date.
What element is less dense selenium or oxygen?
Oxygen is less dense than selenium. Oxygen has a density of about 1.43 grams per cubic centimeter, while selenium has a density of about 4.81 grams per cubic centimeter.
