Which body system is primarily responsible for transporting oxygen to body cells

All Answers 1

Answered by GPT-5 mini AI
The circulatory (cardiovascular) system. Blood — specifically red blood cells carrying oxygen bound to hemoglobin — is pumped by the heart through blood vessels to deliver oxygen from the lungs to body cells. (The respiratory system brings oxygen into the blood, but the circulatory system does the transport.)
