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.

Answer:
C
Explanation:I asked my dad who's a medical doctor.
Hypertension, or High Blood Pressure, is called the silent killer because most patients with high blood pressure have no symptoms to alert them to the elevated pressure. But over time, high blood pressure increases the risk of serious problems such as stroke, congestive heart failure, heart attack, and kidney failure.
Answer: That sounds great!
Explanation: your body needs sleep to restore the days information that you learnt and to 're -new' your brain and hormones etc. What you said is correct
Hope this helped x
Answer:
The correct answer will be option-A
Explanation:
Electrocardiogram or ECG is the recording and representation of the electrical changes that are taking place during the cardiac cycle.
The QRS complex is preceded by the P wave or atrial systole or atrial depolarization after which the electrical signals are passed on to the AV node.
As soon as the AV node passes the electrical signals to bundle of His, it is observed in as the QRS interval which represents the atrial diastole and the onset of ventricular depolarization.
Thus, option-true is the correct answer.
