| Assertion: | Right atrium and right ventricle of heart are known as pulmonary heart. |
| Reason: | Both right atrium and ventricle pump the deoxygenated blood. |
Aging RBCs are phagocytized by macrophages in the mononuclear phagocyte system [sleen or liver] and their components are recycled, EXCEPT for the
| 1. | iron atom from the heme group, which is excreted in bile |
| 2. | globin peptide chains, which are sent to the kidneys for excretion |
| 3. | globin peptide chains, which are converted into bilirubin |
| 4. | heme group (minus the iron atom), which is converted into a green pigment called biliverdin |
