Respiratory and Cardiovascular diseases A) This cardiovascular disease occurs when your heart muscle becomes overworked and lacks strength. Blood pools and causes the body and heart tissues to swell. What is it?

B) This respiratory disease progressively destroys the alveoli which makes gas exchange more difficult?

A. Cardiovascular disease in which the heart fails as a pump is called Heart Failure.

B. Lung disease that is characterized by the progressive destruction of the alveoli associated with difficulty in gas exchange and breathing is Pulmonary Emphysema.

Explanation:

Cardiovascular and pulmonary diseases result in difficulty in the distribution of oxygen and nutrients to the body, making normal body functions difficult for the individual.

A. Heart Failure: is the result of the loss of the heart's pumping capacity, due to the deterioration of the myocardium. Most of the time the overexertion of the myocardium to contract causes the walls of the organ to first hypertrophy, and then to distense, decreasing its ability to contract properly.

One consequence of heart failure is the inability to pump blood to tissues and the accumulation of blood that causes edema in limbs and organs.

B. Pulmonary Emphysema: this condition is due to the loss of elastin, which leads to the progressive destruction of the pulmonary alveoli, as well as parenchymal damage and possibly tissue fibrosis. The result of alveolar destruction is the formation of retained air bubbles, in addition to the loss of the ability to perform gas exchange. The main symptom is persistent respiratory distress.
