Respiration
From Simple English Wikipedia, the free encyclopedia
Respiration is always confused with breathing. Respiration is not the same as breathing! During respiration, oxygen is taken into the blood stream (through the alveolus in the lungs) and carbon dioxide is taken from the blood stream (through the alveolus in the lungs). Carbon Dioxide is then exited out of the human body, whereas oxygen is taken to cells around the body.
Animals obtain carbohydrates, like sugar, by eating them. Plants make their own carbohydrates. They get carbon dioxide from the environment and their energy from the sun. Plants store the Sun's energy in carbohydrates like sugar.
