respiratory Definition

the movement of air or dissolved gases into and out of the lungs

a single complete act of breathing

the physical and chemical processes (such as breathing and diffusion) by which an organism supplies its cells and tissues with the oxygen needed for metabolism and relieves them of the carbon dioxide formed in energy-producing reactions

a respiratory disorder chiefly of newborn premature infants that is characterized by deficiency of the surfactant coating the inner surface of the lungs resulting in labored breathing, lung collapse, and hypoxemia

any of various permanently or intermittently colored conjugated proteins and especially hemoglobin that function in the transfer of oxygen in cellular respiration

a ratio indicating the relation of the volume of carbon dioxide given off in respiration to that of the oxygen consumed

a paramyxovirus (species Human respiratory syncytial virus of the genus Pneumovirus) that is responsible for severe respiratory diseases (such as bronchopneumonia and bronchiolitis) in children and especially in infants —abbreviation RSV

a system of organs functioning in respiration and in humans consisting especially of the nose, nasal passages, pharynx, larynx, trachea, bronchi, and lungs

a state in which one stops breathing

respiratory failure of sudden onset in adults or children that follows injury to the endothelium of the lung (as in sepsis, chest trauma, massive blood transfusion, aspiration of the gastric contents, or pneumonia) and results in the accumulation of protein-rich fluid and the collapse of alveoli leading to difficult, rapid breathing and very low levels of oxygen in the blood —abbreviation ARD—called also adult respiratory distress syndrome

acute respiratory distress syndrome
