Abstract

The red corpuscles, likewise, take part in maintaining neutrality. Although there are no authentic reports of movement of basic ions into or out of the red cells, numerous investigators have shown that there is a migration of acid ions from the plasma into the erythrocytes under conditions of increased acidity such as occurs with higher concentrations of carbon dioxid. The wandering acid ion thus leaves the molecular equivalent of base free in the plasma to combine with the invading acid. There are, therefore, the phosphate and protein systems, which belong strictly to the plasma, and the corpuscle-carbonate system, which may be said to be lent to the fluid portion of the blood.
