What are the 4 formed elements?
Formed Elements
- Erythrocytes (red blood cells) Erythrocytes, or red blood cells, are the most numerous of the formed elements.
- Leukocytes (white blood cells) Leukocytes, or white blood cells, are generally larger than erythrocytes, but they are fewer in number.
- Thrombocytes (platelets)
What are the formed elements and what are their functions?
Formed Elements consist of Erythrocytes (red blood cells that function in oxygen transport), Leukocytes (white blood cells that function in immunity), and Platelets (cell fragments that function in blood clotting). Approximately 8% of an adults body weight is made up of blood.

Why are formed elements called so?
The nonfluid portion of blood consists of various types of formed elements, so called because they are all formed from the same stem cells found in bone marrow.

- Not enough red blood cells produced.
- Too many red blood cells destroyed.
Where are formed elements produced?
red bone marrow
The production of formed elements, or blood cells, is called hemopoiesis. Before birth, hemopoiesis occurs primarily in the liver and spleen, but some cells develop in the thymus, lymph nodes, and red bone marrow.

Also there are forms for taxes; filling one in is a duty to have determined how much tax one owes, and/or the form is a request for a refund.
Where do all formed elements begin their development?
All formed elements arise from stem cells of the red bone marrow. Recall that stem cells undergo mitosis plus cytokinesis (cellular division) to give rise to new daughter cells: One of these remains a stem cell and the other differentiates into one of any number of diverse cell types.
Which formed element contains hemoglobin?
erythrocytes
The most abundant formed elements in blood, erythrocytes are red, biconcave disks packed with an oxygen-carrying compound called hemoglobin.
What are the properties of each element?
Each element has its own unique properties. Each contains a different number of protons and neutrons, giving it its own atomic number and mass number. The atomic number of an element is equal to the number of protons that element contains. The mass number is the number of protons plus the number of neutrons of that element.
