Red blood cells have the responsibility of transporting oxygen throughout the body. About 33% of the weight of a red blood cell is attributed to a specialized protein called hemoglobin. Because of this, red blood cells are often referred to as "bags of hemoglobin."
By diffusion from a high concentration to a lower concentration.
carbon dioxide
Carbon dioxide is a by-product of oxidative metabolism whereby sugars are broken down and their carbon molecules are transformed to C02 with the 02 coming from inhaled oxygen. Carbon dioxide leaves the body by diffusing from the tissue into the blood then leaving the body through the lungs.
carbon dioxide and water
carbonic acid, carbamino compounds and dissolved gas
carbon based molecules
Most plants have special structures on their leaves called stomates. Carbon dioxide is drawn into the leaf tissue through these pore-like structures.
They burn energy from ATP molecules and produce carbon dioxide. Then they wait for diffusion of oxygen to enter and 'recharge the ADP molecules back into ATP molecules so they can burn them again. As a simpler way to say it: In tissue respiration carbon dioxide is released and oxygen is re-absorbed. This the word equation for celluar respiration: C6H12O6 + 6O2 -------------------> 6CO2 + 6H2O + ~38 ATP

In the alveoli
Most plants have special structures on their leaves called stomates. Carbon dioxide is drawn into the leaf tissue through these pore-like structures.
Movement of carbon dioxide is driffen by osmosis from and to the tissue and bloodstream. Also active transport can be used. Amount of CO2 present is monitored by means of the pH of your blood as dissolved CO2 is acidic.
Tissue respiration in animals where an ATP molecule is used to release energy, and at the same time it produces carbon dioxide.
