Oxygen helps liberate biochemical Electricity from meals by acting given that the electron acceptor for your reaction that metabolizes adenosine triphosphate , ATP, one of the human body's main chemical Electricity sources. Metabolic processes that call for oxygen are termed aerobic . By natural means transpiring oxygen is in the shape of molecular oxygen, O2. Atmospheric oxygen is attained by your body during the lungs in tiny air sacs here referred to as alveoli. Inside the alveoli, purple blood cells (rbc's) in slim blood vessels take in oxygen and have it to cells all over the body. Respiration , inhaling and exhaling of air, is subconsciously controlled through the brain in response to fluctuations in carbon dioxide ranges.
