The hemoglobin in mammalian blood is usually thought ofsimply as increasing the amount of O2 that can be carried by eachliter of blood. However, in a lecture on hemoglobin, a respiratoryphysiologist made the following statement: “The presence ofhemoglobin in the blood also makes possible the rapid uptakeof O2 by the blood as it flows through the lungs.” Explain thelecturer’s point.

Hematology

Hematology is the branch of biology. Hematology is the medical field that deals with the treatment of blood disorders and cancers, such as hemophilia, leukemia, lymphoma, and sickle-cell anemia. Hematologists and hematopathologists are medical professionals who specialize in illnesses of the blood and its components.
