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 C
Explanation
In the normal electrocardiogram, the PR interval represents
The PR interval represents the time from the onset of atrial activation to the onset of ventricular activity. During this time, the electrical impulse travels through the atria, the atrioventricular (AV) node, and the bundle of His before entering the ventricles and initiating ventricular depolarization. Option A is incorrect because the atrial depolarization is represented by the P wave. Option B is incorrect because the ventricular depolarization is represented by the QRS complex. Option D is incorrect because there is no such term as “electrical systole” of the ventricles in ECG interpretation.
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.
