The specific heat of blood is ______kcal/kg/*C.

The specific heat of blood is approximately 0.9 kcal/kg/*C. This value suggests that blood requires about 0.9 kilocalories to raise the temperature of one kilogram of blood by one degree Celsius. Understanding specific heat is crucial in the field of perfusion, as it helps in calculating heat transfer, particularly during procedures requiring temperature management such as cardiopulmonary bypass.

The specific heat of blood is relatively higher compared to many other bodily fluids or tissues, indicating its ability to absorb and retain heat efficiently. This property is essential for maintaining the body’s core temperature and ensuring proper metabolic functions during surgical procedures.

The other values presented do not align with the recognized specific heat for blood, highlighting the importance of accurate knowledge in perfusion practice.
