Intrinsic changes in the bronchioles and small bronchi are responsible and they respond to vasoconstrictor inhalants, aminophylline (250mg rw) deep anasthesia or finally to hydrocortisone (100mg IVI repeated if need be) or an infusion of ACTH (60 units in 500cc Darrow's solution). Bronchospasm...
The human respiratory system allows us to breath by air traveling down the oesophagus to the trachea which branches into the Bronchi then branches further into the smaller Bronchioles that End in the surfaces of the Lungs in Alveoli that Diffuse through thin membrane into the Circulatory System. ...
When we breathe, which organs of the respiratory system split into smaller air channels?The bronchial tubes split into smaller air channels called bronchioles as they move through your lungs. The bronchioles terminate in little balloon-like air sacs known as alveoli. There are 600 million alveoli ...

But, the evaluation of AHR is not popular in pediatric clinic. In areas without this means, how can we do next? Asthma is an inflammatory airway disorder that involves also the small airways (defined as the peripheral membra- nous bronchioles <2 mm in diameter) (3). Two decades ago, ...
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming ...
human respiratory systemThe main structures of the human respiratory system include the airways (trachea, bronchi, and bronchioles) and lungs. The diaphragm, a muscular structure that separates the chest and abdominal cavities in humans and mammals, is the main muscle of respiration, aiding in inhal...
asthmaDuring normal breathing, inhaled air travels through two main channels (primary bronchi) that branch within each lung into smaller, narrower passages (bronchioles) and finally into the tiny, terminal bronchial tubes. During an asthma attack, smooth muscles that surround the airways spasm; this...
Background and Objectives: We studied whether the extent of exertional oxygen desaturation and emphysema could cause greater mortality in COPD and asthma independent of airflow obstruction. Materials and Methods: We performed a 5-year longitudinal observ
Ventilation is a medical term that refers to the exchange of gases in the alveoli, which are tiny sacs in the lungs where oxygen and carbon dioxide are exchanged. When someone draws air into the lungs, it enters through the bronchi into the bronchioles and then into the alveoli, where gas...
