Answer to Question 1

Propagate means to reproduce or spread, become larger. Clots that form in the veins located in the deep tissues of the legs tend to increase in size on the side of the clot closest to the center of the body (the proximal side of the clot).

Answer to Question 2

An artifact can be something that appears to exist because of the method used to examine the object, although the artifact does not actually exist (eg, nonexistent objects that appear on x-ray due to the imaging technique). An artifact can also be an object or substance that does not occur naturally but has been introduced or produced as a result of a procedure. Artifacts are generally unintended and may cause confusion.
Artificial describes something produced deliberately for the purpose of replacing or mimicking a naturally occurring substance.
An artificial substance or object actually exists and is introduced intentionally; an artifact may or may not exist and is not introduced intentionally.
