65% of our bodies is made up of oxygen.
Oxygen is essential for producing energy in our cells through the process of respiration. Our bodies take in oxygen from the air we breathe and transport it to cells via the bloodstream. This oxygen is used by cells to fuel metabolic processes that keep our bodies functioning properly.
Oxygen travels through our bodies from inhailingair which is Oxygen
Hemoglobin is the compound in red blood cells that carries oxygen throughout the body. It binds to oxygen in the lungs and transports it to tissues and organs where it is needed for energy production.
Because organisms bodies take in either oxygen of carbon d. into their bodies and through photosynthesis the make sugar and carbon d./oxygen
They depend on the constant waterflow of the ocean through their bodies to obtain food and oxygen and remove wastes.
Aquatic organisms need oxygen to survive
fat and oxygen
Animals need to breathe to get oxygen. Oxygen burns the food within their bodies and releases energy for various activities.
Bodies don't produce oxygen. we breathe it in.
We dont, we breath nitrogen and oxygen...but only the oxygen gets used by our bodies.
Oxygen is essential for our bodies because it is needed for the process of cellular respiration, which produces energy for our cells. Without oxygen, our cells would not be able to function properly and we would not be able to survive.
