Once inhaled air enters the lungs, oxygen is absorbed through the alveoli in the lungs and enters the blood stream. The oxygenated blood travels through the pulmonary vein to enter the left atrium -> left ventricle of the heart, which is the pumping chamber.
The heart then pumps this oxygenated blood via aorta (the majory artery) to all the different muscles and organs in the body. As the oxygenated blood approaches its target destination, oxygen diffuses out of the artery, through the capillaries, and into the oxygen deficient area. The muscle/ organ/ whatever now has oxygen to utilize!
At the same time, HCO3-, a molecule that essentially exists for carbon dioxide to be liquid soluble, diffuses through the capillary into the vein. The deoxygenated blood is then forced back into the right atrium-> right ventricle-> pulmonary artery back into the lungs to be oxygenated once more.
The path is simple, but understand that the process of diffusion is a matter of both chemical equilibria (remember, movement is high solute-> low solute) and osmotic balance.
Cellular respiration occurs in the mitochondria
Respiration
Ventilation is a process humans rely on to maintain high oxygen and low carbon dioxide concentrations at the gas exchange surface. The process that ventilates lungs is breathing. Humans ventilate the lung by negative pressure breathing
Aerobic respiration occurs in the mitochondria of body cells. Anaerobic respiration (glcolysis) occurs in the intracellular cytosol.
Glycolysis occurs in the cytoplasm during the first stage of respiration.
Respiration occurs in the cells.
Breathing is the simple answer. Respiration is also an answer but respiration includes oxygen going into the bloff and throughout the body and Carbon Dioxide going back to the lungs and being exhaled.

trachea
pulmonary ventilation
respiration is the process of yainhaling oxygen to the body and provide the cells.
Breathe, airing, panting, oxygenating, ventilation, and inhalation are synonyms for respiration. Cellular respiration is when a cell exchanges O2 and CO2.
first of all, its ventilation and it means breathing. but don't get mixed up with respiration and breathing they are different!
Anaerobic respiration occurs in some bacteria and fungi as well as yeasts.
