What is the material that is used for respiration and is taken in from the air?
Carbon dioxide is made in our bodies as cells do their jobs. The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out.
What is it called when air is taken into the lungs?
Respiration is the term for the exchange of oxygen from the environment for carbon dioxide from the body’s cells. The process of taking air into the lungs is called inhalation or inspiration, and the process of breathing it out is called exhalation or expiration.
What from the air is needed for respiration?
Glucose and oxygen react together in cells to produce carbon dioxide and water and releases energy. The reaction is called aerobic respiration because oxygen from the air is needed for it to work.
What is the gas taken in during respiration?
One gas (oxygen) is exchanged for another (carbon dioxide). This exchange of gases takes places both in the lungs (external respiration) and in the cells (internal respiration).
Which gas exhaled in breathing?
Inhaled and exhaled air
| Gas | % in inhaled air | % in exhaled air |
|---|---|---|
| Oxygen | 21 | 16 |
| Carbon dioxide | 0.04 | 4 |
| Nitrogen | 79 | 79 |

How is food used in the process of respiration?
The food material, taken in during the process of nutrition, is used by cells and then they provide energy for various life processes. Some organisms use oxygen to break-down glucose completely into carbon dioxide and water, such processes normally take place in cytoplasm.
How does the body store oxygen during respiration?
Remember, during the breathing cycle, when we take air in and let it out, the lungs always store a residual volume of air so that there is sufficient time for the oxygen to be absorbed and for the carbon dioxide to be released. In human bodies, the respiratory pigment is haemoglobin; and the haemoglobin has a high affinity for oxygen.
What makes up the surface of the respiratory system?
A respiratory surface is covered with thin, moist epithelial cells that allow oxygen and carbon dioxide to exchange. Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist. Amphibians use their skin as a respiratory surface.
What kind of carbon dioxide is produced during respiration?
Carbon dioxide and Ethyl alcohol are produced during anaerobic respiration. Also, refer to Respiration and its Types. Stay tuned with BYJU’S to learn more about Respiration in Plants and other related topics @ BYJU’S Biology.
