Blockage of Pulmonary Blood Flow by a Traveling Clot or Similar

Question

Blockage of pulmonary blood flow by a traveling clot or similar obstruction is
A) emphysema.
B) COPD.
C) anoxia.
D) pulmonary embolism.
E) pneumothorax.

Accepted Answer

A traveling clot or similar obstruction that blocks pulmonary blood flow is known as pulmonary embolism. Emphysema and COPD are chronic lung diseases that are not related to blockage of pulmonary blood flow. Anoxia is a condition where there is insufficient oxygen supply to tissues, but it is not specific to the pulmonary system. Pneumothorax is characterized by the accumulation of air in the pleural cavity, causing lung collapse, and is also not related to blockage of pulmonary blood flow.
