The physiology of a cow's respiration system is exactly the same as a human's or any other mammal. Oxygen is taken into the lungs via expansion of the lungs by the downward force exerted by the diaphragm, oxygen is exchanged with carbon dioxide at the capillary level in the alveoli of the lungs, and carbon dioxide is released outside by exhaling, when the diaphragm exerts and upward force and the lungs contract. This process repeats throughout the cow's life, and is an involuntary movement that keeps her alive.
