Answer 1

Answer first question:

Emphysema is a disease condition of lungs in which patient experiences shortness of breath.

In emphysema alveoli are damaged leads to the reduced surface area of the lungs to accommodate oxygen.

Emphysema causes increased pressure inside the arteries that connect heart and lungs. This will cause condition called corepulmonale.

Corepulmonale is the alteration in the structure and function of the right ventricle due to pulmonary reasons mainly pulmonary hypertension. This right ventricular failure leads to corepulmonale.it is usually diagnosed as congestive heart failure.
