The hematopoietic activity in the embryonic phase is carried out by the liver.
The hematopoietic activity in the embryonic phase is carried out by the spleen.
The hematopoietic activity in the embryonic phase is carried out by the yolk sac.
The hematopoietic activity in the embryonic phase is carried out by the bone marrow.
The red blood cells of newborns have a longer lifespan than those of adults.
Physiologic anemia occurs in newborns due to a decrease in oxygenation and an increase in erythropoietin production.
Pathologic anemia in newborns is characterized by a hemoglobin level lower than 13.5 g/dL during the first month of life.
Microcytic anemia is caused by a deficiency of vitamin B12 and folates.
Macrocystic anemia can be megaloblastic or non-megaloblastic.
