Question

Quizplus · Accepted Answer

The most significant contribution to keeping these individuals alive is likely the oxygen and carbon dioxide carrying capacity of the transfused blood. This is because both Hirohito and Zhou Enlai were likely experiencing respiratory distress or failure, which would impair their ability to efficiently exchange oxygen and carbon dioxide in their lungs. By providing fresh blood with healthy hemoglobin molecules, the transfusions could help ensure adequate oxygenation of their tissues and removal of carbon dioxide, which is essential for cellular metabolism and survival. While the other functions listed (supplement of hormone levels, provision of organic nutrients, provision of albumin and fibrinogen, provision of immune antibodies) may also be important in maintaining overall health and organ function, they are less likely to be the primary factor in keeping these individuals alive during their critical periods.
