Q

Blood functions

A

Transportation (brings nutrients O2 and hormones and takes CO2 urea and uric acid)
Regulation (of pH CO2 lactic acid electrolytes ions)
Restriction of fluid loss (enzymes clot at injury sites)
Defense (WBCs and antibodies protect against toxins and pathogens)
Stabilization (volume of blood flow in areas cools or heats body temp)
