Final answer:
In hematopoiesis, the percentage of pluripotent stem cells that become leukocytes and erythrocytes varies. Leukocytes, involved in the immune response, make up a smaller percentage compared to erythrocytes, which carry oxygen.
Step-by-step explanation:
Hematopoiesis is the process by which the formed elements of blood, including leukocytes and erythrocytes, are produced. Pluripotent stem cells differentiate into various cell types, including leukocytes and erythrocytes. In terms of the percentage, it is difficult to provide an exact number as it depends on the specific conditions and needs of the body. However, leukocytes, which are involved in the immune response, make up a smaller percentage of the total formed elements compared to erythrocytes. Erythrocytes, also known as red blood cells, are responsible for carrying oxygen throughout the body and make up the majority of the formed elements in the blood.
