DISEASES OF THE RESPIRATORY SYSTEM

Anatomy: The organs comprising the respiratory system are: Nose, throat, wind-pipe (trachea) and lungs. The nose is the passage carrying pure air from outside to lungs via the wind-pipes and carrying impure air from lungs to outside. The lung air-passage (nostrils and wind-pipe) is designed not only to carry air in and out but also to warm it during its passage. The Wind-pipe begins at the back of the tongue, where it is called Pharynx; the portion of it that we see in front of the neck is called Larynx in its upper part, and Trachea in its lower part. When it enters the lungs, it is called Bronchus and the minute ramifications of the Bronchus inside each lung are called Bronchioles. The lungs are like a pair of bellows, being made up of air-cells. The air that we inhale (inspire) parts with its oxygen to the blood, brought to it from right side of the heart thereby purifying it. As soon as it is done, the lungs contract and expel the air, laden this time with carbonic acid gas, imparted to it (air) by the blood brought from the heart. This expelled air (expiration) is deficient in oxygen but is full of carbonic acid and is therefore poisonous to any one who cares to inhale it.

General Remark: It has been said that cold is responsible for half the ills, which flesh is heir to. Cold directly produces very few diseases; but by lowering the vitality of tissues it indirectly produces many of them. Diseases caused by germs are especially helped forward by exposure to cold—such as, catarrh, influenza, pneumonia, dysentery, sore-throat, nasal ulcer, jaundice, diarrhoea, tonsillitis, whooping cough, pleurisy, etc.
