Respiration is the process that carries oxygen to the cells and removes carbon dioxide from them. Blood carries the oxygen to the cells.
The Respiratory system carries oxygen and carbon dioxide
Hemoglobin
Red blood cells in blood carry oxygen throughout the body. The actual chemical substance in red blood cells that carries oxygen is hemoglobin. Hemoglobin also carries carbon-dioxide when passed through capillarys, the part where the carbon dioxide is exchanged with the oxygen. capillaries are a cell thick for the lower blood presure.
plasma has a little
