which term refers to the autonomic feedback response to changes in blood chemistry?

baroreflex

accommodation reflex

chemoreflex

flexor reflex

Explanation:

To solve this, we analyze each option:

• Baroreflex: Responds to blood pressure (stretch) changes, not blood chemistry. Eliminate.
• Accommodation reflex: Adjusts eye focus (for near/far vision), unrelated to blood chemistry. Eliminate.
• Chemoreflex: Specifically refers to autonomic feedback responding to blood chemistry changes (e.g., O₂, CO₂, pH). Matches the question.
• Flexor reflex: A spinal reflex for limb withdrawal (pain), unrelated to blood chemistry. Eliminate.
