Question 10 • NY-Life Science: BiologyTerm 2 Hillcrest

Keisha cut her hand, which caused a lot of bleeding. Which mechanism did her body use to minimize the blood loss?

Answer
A
Blood thickened in the blood vessels near the cut.
B
Blood vessels near the cut dilated.
C
Blood stopped flowing in blood vessels near the cut.
D
Blood vessels near the cut constricted.

Explanation

When a blood vessel is injured, it constricts, or narrows, near the cut. This reduces blood flow to the area and helps minimize blood loss while clotting takes place. Therefore, the correct choice is “Blood vessels near the cut constricted.”
