Final answer:
Sideroblastic anemia is characterized by increased iron absorption and deposition in the body, specifically in the liver and other tissues.
Step-by-step explanation:
Sideroblastic anemia is characterized by increased iron absorption and deposition in the body, specifically in the liver and other tissues. Excessive iron is released or introduced into the body, leading to the accumulation of iron in various tissues. This may occur due to repeated blood transfusions, excessive breakdown of red blood cells, inadequate synthesis of hemoglobin, or abnormalities in iron metabolism.
In sideroblastic anemia, the excess iron is deposited in the liver as hemosiderin, a form of colloidal iron oxide in association with protein. Iron metabolism is disturbed, mainly due to decreased formation of hemoglobin and abnormalities in the serum iron concentration. Iron plays a crucial role in transporting oxygen to the tissues, cellular respiration, and the functioning of hemoglobin and other respiratory enzyme systems.
Overall, sideroblastic anemia is characterized by increased iron deposition in the liver and other tissues, leading to disruptions in iron metabolism and various symptoms associated with iron overload.
