Answer: Iris Diaphragm is a device that controls the amount of light that exits the condenser of a microscope. There by controlling the illumination of the specimen and, more relevantly, the degree of contrast between specimen and background.
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.

The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs. The blood here passes through capillaries adjacent to alveoli and becomes oxygenated as part of the process of respiration.
