(b) the flow of blood increases manifold

(c) the flow of blood is obstructed

(d) the pressure of blood increases manifold

Answer 1

(c) the flow of blood is obstructed

The presence of air bubble in blood, known as air embolism, occludes blood vessels. The flow of blood is obstructed causing strokes, heart attacks, pulmonary complications. An arterial air embolism is far more dangerous than a venous embolism since it prevents oxygenated blood from reaching the target organ and cause ischemia.
