Q

Functions of Blood

A

Provides a medium for the maintenance of homeostasis in the cell’s environment Functions as a transportation system, bringing nutrients and oxygen to the cells and removing wastes and carbon dioxide from interstitial fluid around the cells Integrates various organs through hormones Provide buffers for acid-base balance Destroys foreign organisms through phagocytosis and antibody action Provide distribution of body heat & heat conservation Prevent its own loss through hemostasis (coagulation) mechanisms

Q

Calculation of Total Maximum Oxygen Carrying Capacity

A

Total blood Hb (g) = blood volume (ml of blood) X hemoglobin concentration (g Hb/ml of blood) Total oxygen carrying capacity = (total g Hb) X (1.34 ml O2/g Hb)
