Plants take in what and release oxygen gas? How do animals obtain oxygen? How do plants get rid of water from cellular respiration? How does carbon dioxide get into a plant cell? I I am a little confused as to how plants release O2 and CO2. I know one is photosynthesis and the other...
practicing Tai Chi or dancing. Sometimes I can see kids playing badminton, hide-and-seek or flying a kite there. I think parks really play a very important role in cities, because trees in parks
They produce oxygen and absorb carbon dioxide(二氧化碳), a gas that animals,including humans, produce naturally as they breathe. But because carbon dioxide also comes from cars andfactories, there is too much of it in the atmosphere, which is contributing to global warming. If everyoneplanted ...

Your lungs, for example, breathe in oxygen and exhale carbon dioxide (one of your body's waste products). The lungs transfer oxygen to the blood, which is carried to the heart for distribution throughout the rest of the body. The blood carries waste carbon dioxide back to the lungs, ...
The alveoli are the only place in the body where oxygen exchange for carbon dioxide occurs – a vital life-sustaining process. When a large amount of foreign material clogs these tiny air sacs, it causes difficulty breathing and significant inflammation or infection, leading to pneumonia....
Humans and animals need oxygen to exist. Without it, most living things will die. But where does oxygen come from? Trees. Trees can take in much carbon dioxide (二氧化碳) which may be bad for our environment and produce oxygen for us to breathe. All people know that trees are important ...
Yawning helps to draw in more oxygen or remove a buildup of carbon dioxide. This theory helps explain why we yawn in groups. Larger groups produce more carbon dioxide, which means our bodies would act to draw in more oxygen and get rid of the excess CO2. However, if our bodies make us...
Plants breathe in carbon dioxide (CO ) and breathe out oxygen (O ) which we humans need to live. They can also add 2 2 moisture to the air if its too dry, making it more comfortable for us to breathe. ___ Scientists have discovered that plants have the ability to take in harmful ...
