carries oxygen-depleted blood away from the heart, to the lungs, and
returns oxygenated blood back to the heart.
systemic circulation - ANSWERS-The part of blood circulation that

Hemoglobin - ANSWERS-(Fe) only binds to respiratory pigment in
vertebrate blood, but is common respiratory pigment in hemolymph as
well.
Tracheal Breathing - ANSWERS-Insects, and some other invertebrates,
