Because humans cannot utilize carbon dioxide as plants do, so they are dumped out as waste via exhalation.
Carbon dioxide
Carbon Dioxide :)
Carbon dioxide is a waste product of cells produced during cellular respiration as cells break down nutrients to create energy. It is then transported in the blood to the lungs where it is exhaled from the body.
No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
Carbon dioxide is probably the most important.
Carbon dioxide is the waste product that is picked up from cells by blood. It is transported to the lungs where it is expelled from the body during exhalation.
Carbon dioxide is removed from cells by a process known as diffusion.
Yes, oxygen and carbon dioxide are exchanged in the human body through the process of respiration. When we inhale, we take in oxygen from the air which is used by our cells for energy production. Carbon dioxide, a waste product of this process, is then expelled from the body when we exhale.
Carbon dioxide
Cells produce waste chemicals such as carbon dioxide, which is a byproduct of cellular respiration. This waste chemical is expelled from cells into the bloodstream and ultimately eliminated from the body through the lungs during exhalation.
Carbon dioxide is an example of waste from a cell.
Carbon dioxide is a waste product to humans and animals. Trees "breath" carbon dioxide and oxygen is their waste product (during daytime). Animals and humans breath oxygen and breath out carbon dioxide. When our cells circulate, they go through the pulmonary artery to the lungs and collect oxygen. They then go back through the heart and out into the rest of our body. Cells bring oxygen to the parts of our body that need it. Their waste is carbon dioxide which is exhaled.
