Asthma can affect people of every one of ages and races. It is estimated to modify about 10% of children and 6% of adults, moreover the incidence is increasing around the terraqueous globe.

The origin of asthma

The song we breathe, to reach the lungs, passes end a tube that begins in the faux, called the trachea. At its base, the trachea is divided into two smaller conduits, the two bronchi, each discharging a lung. Bronchi, in proclivity, are subdivided into segments with progressively smaller size. The smallest of them, the millions existing at the ends of this "tree", are called bronchioles. Each bronchiole ends in a pygmean purse, called alveoli. And it is precisely to this place, in the alveoli that gas truck occurs, the blood absorbs oxygen and removes carbon sub-oxide in the air that now move the opposite way - the alveoli, through the bronchi and the trachea, into the nose and orifice, and thence out of the body.

In a bout of asthma, this machinery malfunctions due to narrowing of the bronchi caused by muscle contraction of the walls of channels - a miracle known as bronchospasm - and also by the increase in the production of secretion (sputum) from the lungs.

In the bronchial walls of asthmatics are cells that, subordinate to stimulation of different agents, can mainspring inflammation and consequent bronchospasm. Perpetuated while the inflammation becomes more sensitive bronchi, worsening the distemper course.

Cause

The asthma attacks can be triggered by several factors. The contented or caregiver should observe what usually trigger the pinch, to improve the effectiveness of prophylactic measures.
