Airway blockage or limitation is a hallmark of the group of chronic, irreversible respiratory disorders known as a chronic obstructive pulmonary disease (COPD). It is not treatable or contagious. Reduced pulmonary airflow brought on by elevated inflammation characterises asthma and chronic obstructive pulmonary disease (COPD).
Two primary phenotypes have been established based on clinical, pathological, and radiological characteristics:
Emphysema type A and type B patients are referred to as "pink puffers" and "blue-bloaters," respectively (chronic bronchitis)
Dyspnea is the most common symptom in Type A patients, while cough and hypersecretion are mild. The main causes of the decreased diffusing capacity for carbon monoxide (DLCO) and frequently enlarged lung volumes in Type A patients include non-homogeneous ventilation and ventilation-perfusion mismatch. Type A patients also seldom have hypercapnia or recurrent heart failure.
Mucous hypersecretion is the predominant symptom of type B patients, although dyspnea is mild. While lung capacities are not expanded and carbon monoxide diffusing ability is often conserved, type B patients frequently exhibit hypercapnia, hypoxia, secondary pulmonary hypertension, and cardiovascular comorbidities.

True- an involuntary reflex is a reaction that happens when something else occurs. A involuntary reflex is something our body is “programmed” to do automatically.
Answer:
Try not to go on their social media as much and you shouldn't have to worry about it. If you still keep doing it just keep away from the fried requests and try not to message their friends.
Explanation:
Stenting is an alternative to endarterectomy for treatment of carotid artery stenosis, but long-term efficacy is uncertain.
What is Stenting?
A stent is a small tube made of wire mesh. It holds open an artery and stays there indefinitely.
If a coronary artery (a blood vessel that supplies an accumulation narrows the heart muscle. Plaque is a fatty buildup that can lessen the blood flow. if there is less blood flow Chest pain may be caused by damage to the heart muscle.If a clot develops and entirely obstructs the a portion of the heart muscle's blood flowthe heart attack happens.Stents maintain coronary artery patency.and lower the risk of having a heart attack.
A stent is deployed by collapsing it and placing it over the
the balloon catheter. It is then brought close to the obstruction.
