The spleen is the largest collection of lymphoid tissue in the body. It is normally palpable in preterm infants, in 30% of normal, full-term neonates , and in 5% to 10% of infants and toddlers. A spleen easily palpable below the costal margin in any child over the age of three to four years should be considered abnormal until proven otherwise.
Absorption of dietary iron in iron salt form (as in most supplements) varies somewhat according to the body's need for iron, and is usually between 10% and 20% of iron intake. Absorption of iron from animal products, and some plant products, is in the form of heme iron, and is more efficient, allowing absorption of from 15% to 35% of intake.
The iron from the red blood cells is either released by the red pulp macrophages or stored in the erythrocyte itself in the form of ferritin. Also, the erythrocyte can store larger amounts of iron in the form of hemosiderin (an insoluble complex of partially degraded ferritin), and large deposits of this can be seen in the red pulp macrophages.
Iron helps to strengthen the body's resistance to infections and diseases by facilitating the growth and health of immune cells. So, it is vital for the proper functioning of the immune system.
Storage of iron. In the liver, Kupffer cells store excess iron from catabolism of heme from the breakdown of red blood cells. In bone marrow and spleen, iron is stored in MPS cells mostly as ferritin; in iron overload states, most of the iron is stored as hemosiderin. Clearance of heparin via heparinases.

Hemosiderin or haemosiderin is an iron-storage complex that is composed of partially digested ferritin and lysosomes. The breakdown of heme gives rise to biliverdin and iron. [1] [2] The body then traps the released iron and stores it as hemosiderin in tissues. [3] Hemosiderin is also generated from the abnormal metabolic pathway of ferritin. [3]
According to Kukushkin, the memories stored in non-brain cells in other parts of the body are memories strictly related to the roles that those specific cells play in human health. Thus, he detailed:
