filled with fats, fat cell production begins 4 years of age and completed at 18 years of age.

In what organ does the following happen: Absorption of Vitamin B12. Produce intrinsic factor. Vitamin B12 is a normal requirement for the normal erythropoiesis

The adult total body weight in bone marrow

continuation of prenatal hematopoiesis.

In the medullary stage: The birth bone marrow have a total of body weight?

In the extramedullary hematopoiesis, this organ is not really for differentiation and maturation. -It stores intrinsic factor produced by the stomach.

In the extramedullary hematopoiesis, the spleen, liver and lymph nodes revert back to the immature RBC because of the following reasons:

Bone marrow is unable to meet the demands placed on it, as in the

Cellular components which the body can still use

functions to destroy cellular components which the body can still use (iron and globin).

Bone Marrow becomes dysfunctional in cases such as

To absorb the vitamin B12 we need these _______ from the stomach to absorb the Vitamin B12.

For normal erythropoiesis, we need what type of vitamin?

Maturation of lymphocytes and monocytes. Reservoir of blood cells which can be released from the pulp (red pulp – RBC) into the circulation on demand.

• Outside the confines of the bone marrow. • In certain abnormal circumstances, the spleen, liver, and lymph nodes revert back to producing immature blood cells (they can able to produce small amount of blood).

The extramedullary hematopoiesis mature in the?

In certain abnormal circumstances, the spleen, liver, and lymph nodes revert back to producing immature blood cells (they can able to produce small amount of blood). It means the RBC, WBC, and platelet is?

2 Types of Post-natal Hematopoiesis:

Are not contained in the peripheral blood, it migrates to the tissues where they become macrophage (mononuclear phagocyte system

Appendicular and axial skeleton/flat and irregular bones (sternum, ribs, pelvis, iliac crest of pelvis, skull, vertebrae), developing blood cells, Iliac crest of pelvis – Puncture site.

The fat cell production begins at? And ends in?

Overproliferation of a cell line

Differentiation and maturation of lymphocytes that originate in the bone marrow.

Infiltration by malignant cells

(Spleen, bone marrow, thymus, intestinal tract) Gut associated lymphatic tissue.
