Hyposplenism is used to describe reduced ('hypo-') splenic functioning, but not as severely affected as with asplenism. Functional asplenia occurs when splenic tissue is present but does not work well (e.g. sickle-cell disease, polysplenia) – such patients are managed as if asplenic – while in anatomic asplenia, the spleen itself is absent.
The spleen is an important immunological organ that acts as a filter for red blood cells, triggers phagocytosis of invaders, and mounts an immunological response when necessary. [2] Lack of a spleen, called asplenia, can occur by autosplenectomy or the surgical counterpart, splenectomy. Asplenia can increase susceptibility to infection. [3]
Spleen produces all types of blood cells during fetal life; Production of opsonins, properdin, and tuftsin. Release of neutrophils following myocardial infarction. [19] Creation of red blood cells. While the bone marrow is the primary site of hematopoiesis in the adult, the spleen has important hematopoietic functions up until the fifth month ...
The spleen typically acts as a filter for blood, and targets pathogens and other damaged cells within circulation. Removing blood contaminants promotes entire-body homeostasis. The following facts about the spleen's role in normal body functioning are crucial to understanding the implications of HS on the overall health of the individual:
The human body has 78 organs and each one performs a variety of important functions. While it's possible to live without organs like the appendix, gallbladder, or spleen, several of our organs are ...
The spleen is an important organ in regard to immunological function due to its ability to efficiently destroy encapsulated bacteria. Therefore, removal of the spleen runs the risk of overwhelming post-splenectomy infection , a medical emergency and rapidly fatal disease caused by the inability of the body's immune system to properly fight ...
The spleen's marginal zone contains multiple subtypes of macrophages and dendritic cells interlaced with the MZ B cells; it is not fully formed until 2 to 3 weeks after birth in rodents and 1 to 2 years in humans. [6]
