Respiration process is what through which we inhale oxygen, which is consumed by our body to perform combustion (oxidation) processes that eventually produce ATP.
The respiratory tract is important in humans because the body's cells need oxygen in order to survive. The respiratory system consists of the pulmonary arteries, pulmonary veins, lungs, trachea, bronchioles, and the alveoli. All these components work together in order to oxygenate the tissues of the body. For example, when you take a breath, your diaphragm drops and your ribcage expands outwards. This allows air to enter where the tiny capillaries surrounding the alveoli come in contact with oxygen where it dissolves into the blood.
