Most of the adult body's bone marrow is in the pelvic bones, breast bone, and the bones of the spine. Blood donors report feeling a sense of great satisfaction after making their blood donation. Hemoglobin, the main oxygen-carrying molecule in red blood cells, carries both oxygen and carbon dioxide. In almost all vertebrates, including humans, hemoglobin is contained exclusively within the red cells (erythrocytes). In many invertebrates, these oxygen-carrying proteins are freely soluble in the blood; in vertebrates they are contained in specialized red blood cells, allowing for a higher concentration of respiratory pigments without increasing viscosity or damaging blood filtering organs like the kidneys. Under normal conditions in adult humans at rest, hemoglobin in blood leaving the lungs is about 9899% saturated with oxygen, achieving an oxygen delivery between 950 and 1150 ml/min[26] to the body.
