In exhaling, the oxygen mixes with the surrounding atmosphere. On inspiration, the oxygen, along with other gasses present, enters the nose and gets warmed and moisturised while dust is filtered out. After that it leaves the nasal cavity and enters the pharynx, just behind the soft palate and the tongue, and eventually passes down the larynx into the (lungs,) bronchi and through the alveoli into the bloodstream.
The lungs are the organs where oxygen enters the body and carbon dioxide leaves it through the process of respiration. Oxygen is taken in when breathing and carbon dioxide is released when exhaling.
Actually that oxygen is used up already out of the air breath. What you breath out is carbon dioxide and that stays in the air (which cause global warming) or is used by plants and then changed back into oxygen. If so some is dissolved in water to make soft drinks
After entering the nose or mouth, oxygen travels down the windpipe (trachea) and then into the lungs. In the lungs, oxygen is exchanged for carbon dioxide in the alveoli, small air sacs where oxygen is taken up by red blood cells and transported to the rest of the body.
They are breathing pores, in which oxygen enters and carbon dioxide leaves. They help the grasshopper to breath sort of how we breath through are nose and mouth.
Oxygen is actually breathed in by animals. It is carbon dioxide which is exhaled by animals. Plants take in carbon dioxide and give off oxygen.
In the process of photosynthesis, leaves take in carbon dioxide, converting the carbon in it to plant material, and release oxygen
stoma present in leaves gives out oxygen we breathe so that we can get oxygen through stoma present in leaves
The mouth or nose inhales oxygen. Then the oxygen goes into the lungs.
Oxygen exits the plant through the stomata. Water vapors also exits through the stomata.
because it has its waxy cuticle to absorb and conserve water. it also has has its stomata which is its nose to breath. they inhale carbon dioxide and exhale oxygen
Oxygen itself will not cause sores in your nose. If you are receiving the oxygen via nasal prongs or some sort of pipe that enters the nose, the pipe or prongs can cause irritation of the skin, resulting in sores.
Leaves are a part of a plant. Plants TAKE IN carbon dioxide and GIVE OFF oxygen.THEREFORE, leaves do not give oxygen. :D Leaves are however key part of the photosynthesis process.
