Question

Inject blue dye into bloodstream and what happens?

A) Immediate heart rate increase
B) Blood turns blue
C) Dye spreads throughout the circulatory system
D) No effect on circulation

Answer 1

Injecting blue dye into the bloodstream results in the dye spreading throughout the circulatory system for medical tracing purposes without causing an immediate heart rate increase or changing the color of the blood.

Step-by-step explanation:

When you inject blue dye into the bloodstream, what happens is that the dye spreads throughout the circulatory system (C). The blue dye would not immediately increase heart rate, change the color of the blood throughout the body, or have no effect on circulation; instead, it would disperse via the blood to the various parts of the body where the circulatory system reaches. This is part of a process called dye tracing, which is often used in medical diagnostics to visualize blood flow and detect abnormalities.
