Among the four major blood types, the average age of blood type B is 77 years old, ranking second. Which one is the first?
Blood is a tissue that circulates in the heart and blood vessels , accounting for 1/13 of the body weight. It is mainly composed of plasma and blood cells. It has functions such as regulating body temperature, regulating osmotic pressure, regulating acid-base balance, transportation, and defense.
Blood group is divided into ABO blood group system and Rh blood group system. Each blood group system is determined by genetic factors and has immune characteristics. The most common blood group is the ABO blood group (divided into a, B, AB and O), followed by the Rh blood group system (mainly divided into Rh positive and Rh negative).
