The system in living organisms that takes up oxygen and discharges carbon dioxide in order to satisfy energy requirements. The respiratory system consists of all the organs involved in breathing. These include the nose, pharynx, larynx, trachea, bronchi and lungs. The respiratory system does two very important things: it brings oxygen into our bodies, which we need for our cells to live and function properly; and it helps us get rid of carbon dioxide, which is a waste product of cellular function.In humans the respiratory tract is the part of the anatomy involved with the process of respiration.The respiratory tract is divided into 3 segments:upper respiractory tract,Respiratory airways,Lungs.The respiratory tract is a common site for infections.
"A leukotriene antagonist (sometimes referred to as a leukast) is a drug that inhibits leukotrienes, which are fatty compounds produced by the immune system that cause inflammation in asthma and bronchitis, and constrict airways.
Leukotriene inhibitors (or modifiers), such as montelukast (trade names Singulair and Montelo-10), zafirlukast, Pranlukast and zileuton, are used to treat those diseases. They are less effective than corticosteroids and thus less preferred in the treatment of asthma"
