Question

(3.3.b) bleeding: quiz
how does the body initially respond to severe bleeding?
the body attempts to maintain an oxygen - rich blood flow to the vital organs.
the body attempts to maintain an oxygen - rich blood flow to the neck and head.
blood flow to the extremities is increased to provide energy for the body to cope with the emergency.
blood pressure decreases in order to conserve all remaining blood within the body.

Explanation:

When the body experiences severe bleeding, it prioritizes the vital organs (such as the heart, brain, and lungs) to ensure their proper function and survival. It redirects blood flow to maintain an oxygen - rich supply to these organs. The body does not specifically target just the neck and head, nor does it increase blood flow to extremities during severe bleeding as that would waste blood. Also, blood pressure initially increases (not decreases) as the body tries to compensate for blood loss to maintain perfusion to vital organs.

Answer:

The body attempts to maintain an oxygen - rich blood flow to the vital organs.
