What are the hematopoietic organs?
Hematopoiesis is the production of all of the cellular components of blood and blood plasma. It occurs within the hematopoietic system, which includes organs and tissues such as the bone marrow, liver, and spleen.
What is the hematopoietic system composed of?
The hematopoietic system consists of the bone marrow and the cells it produces, including leukocytes, erythrocytes, and thrombocytes. The highly proliferative nature of bone marrow makes it a target for toxicants that preferentially attack rapidly dividing cells.
What is the first hematopoietic organ?
In the first trimester, hematopoiesis can be found in the spleen, but in the late first trimester and throughout most of the second trimester and well into the third trimester, the major hematopoietic organ is the liver. This extramedullary hematopoiesis (blood cell production outside the marrow) is normal.
What are the 5 hematopoietic tissues?
Hematopoietic Tissue
- Neoplasm.
- Lymphatic Tissues.
- Protein.
- Bone Marrow.
- Hematopoiesis.
- Precursor.
- Spleen.
What hematopoietic means?
: the formation of blood or of blood cells in the living body.
What is a hematopoietic cell?
An immature cell that can develop into all types of blood cells, including white blood cells, red blood cells, and platelets. Hematopoietic stem cells are found in the peripheral blood and the bone marrow. Also called blood stem cell. Enlarge. Blood cell development.
What is the function of the hematopoietic?
Hematopoietic stem cells (HSCs) are responsible for the production of mature blood cells in bone marrow; peripheral pancytopenia is a common clinical presentation resulting from several different conditions, including hematological or extra-hematological diseases (mostly cancers) affecting the marrow function, as well …
Is the liver a hematopoietic organ?
During human development, the liver and marrow both function as hematopoietic organs, but little is known about differences in the production of macrophages and neutrophils by these two organs.
What is a hematopoietic precursor?
Hematopoietic stem cells (HSCs) are multipotent precursors that have self‐renewal capacity and the ability to regenerate all the different cell types that comprise the blood‐forming system (Bonnet, 2002; McCulloch and Till, 2005).
What is the function of hematopoietic stem cell?
What is the definition of hematopoiesis quizlet?
Define: Hematopoiesis. – a continuous, regulated process of blood cell production that includes cell renewal, proliferation, differentiation, and maturation. – results in the formation, development, and specialization of all functional blood cells.

What is the hematopoietic system?
The hematopoietic system is formed by bodies responsible for haematopoiesis, or the production of the cellular elements of blood: red blood cells, white blood cells and platelets.
What is hematopoietic disorder?
Hematopathology. Hematopathology or hemopathology is the study of diseases and disorders affecting blood cells, their production, and any organs and tissues involved in hematopoiesis, such as bone marrow, the spleen, and the thymus. Diagnoses and treatment of diseases such as leukemia and lymphoma often deal with hematopathology;
