involves an abnormally enlarged gas exchange system and the destruction of alveolar walls
The Correct Answer is {"dropdown-group-1":"B"}
Emphysema is a lung disease that involves damage to the alveoli (tiny air sacs in the lungs), causing them to become stretched out and lose their elasticity. This leads to an abnormally enlarged gas exchange system and the destruction of alveolar walls
Transudative effusion: An effusion is an abnormal buildup of fluid in a body cavity, such as the pleural cavity around the lungs. Transudative effusions occur when fluid leaks out of blood vessels due to changes in pressure or protein levels, rather than from inflammation or injury.
Exudate effusion: This type of effusion occurs when fluid leaks out of blood vessels due to inflammation or injury. The fluid contains high levels of protein and cellular debris, and may be caused by conditions such as pneumonia, cancer, or autoimmune disorders.
D. Abscess: An abscess is a localized collection of pus, usually caused by a bacterial infection. It can occur in various parts of the body, including the lungs.
An abscess in the lung can cause symptoms such as coughing, chest pain, and fever.

Correct Answer is A
Explanation
A pulmonary embolism (PE) occurs when a blood clot, typically originating from the deep veins of the legs or pelvis, travels through the bloodstream and lodges in one of the pulmonary arteries in the lungs.
Deep venous thrombosis (DVT) is the most common source of pulmonary emboli. DVT occurs when a blood clot forms in the deep veins of the legs, pelvis, or arms, and can develop due to prolonged immobility, surgery, trauma, cancer, pregnancy, hormone therapy, or genetic factors.
Endocarditis, valvular heart disease, and left heart failure are not typical sources of pulmonary emboli. Endocarditis is an infection of the heart valves and lining, which can lead to valve damage and heart failure, but does not usually cause blood clots. Valvular heart disease, which includes conditions such as aortic stenosis and mitral regurgitation, can cause blood flow disturbances and increase the risk of thrombosis, but does not directly cause blood clots. Left heart failure, which occurs when the left ventricle of the heart is unable to pump effectively, can cause fluid buildup in the lungs, but does not typically cause blood clots to form.
Correct Answer is C
Explanation
When the left ventricle is unable to pump blood effectively, blood backs up into the lungs, leading to pulmonary congestion and edema. This can cause symptoms such as shortness of breath, coughing, and wheezing. Decreased venous pressure and hyperoxygenation are not typically associated with left ventricular failure. Bradycardia may occur in some cases, but it is not a defining feature of left ventricular failure.
