Red Blood Cell
The only true cell among the formed elements of blood is the white blood cell (leukocyte). Red blood cells (erythrocytes) and platelets (thrombocytes) are not considered true cells because they lack a nucleus and other organelles.
Thrombocytes are the smallest formed elements in the blood. In my Medical Terminology book, it says "The smallet formed elements found in blood are platelets. Although they are sometimes called thrombocytes, they are not true cells, as the term erroneously suggests, but merely fragments of cells."
The most primitive blood cell is called a hematopoietic stem cell. These cells have the ability to develop into various types of blood cells, including red blood cells, white blood cells, and platelets.
Immature cell types released into the blood circulation are called "blast cells." These are undifferentiated cells that have the potential to develop into various types of mature blood cells, such as red blood cells, white blood cells, or platelets. The presence of blast cells in the blood may indicate abnormal cell development, as seen in conditions like leukemia.
Red Blood Cell
blood cell count, hemoglobin, and hematocrit
Angioblast
Iam not sure but it is plasma
Iron

The primary mineral found in the blood is iron. It is the element at the center of the hemoglobin molecule - in the red blood cell.
Platelets, or thrombocytes, are the smallest formed element in the blood. Made of cell fragments, platelets are part of the blood clotting process. Non-formed clotting factors also are critical to blood clotting.thrombocytes
Platelets or thrombocytes are a component of blood tissues involved in the formation of blood clots. Platelets are not cells, but are cell fragments.
Pleuripotent stem cell
A basic cell that has the potential to develop into many different kinds of cells is called a stem cell. Stem cells can be found in the umbilical cord blood right after birth.
People (and most animals) develop from gametes: special cells that each contain half the genetic material needed to produce a new being.In the female, this is called the egg cell; in the male, this is called the sperm cell.
