Final answer:
Hemochromatosis (option a) refers to an iron overload with injury to the tissues, often caused by genetic factors leading to excessive iron absorption and storage in the body.
Step-by-step explanation:
The term for an iron overload with injury to the involved tissues is a. Hemochromatosis. Hemochromatosis is a condition characterized by excessive iron accumulation in the body, particularly in organs such as the liver, pancreas, and heart, which can ultimately lead to tissue damage.
This overload may occur due to genetic factors that affect iron metabolism, causing the body to absorb too much iron from foods. It is also referred to as hereditary hemochromatosis when it is caused by a genetic disorder, leading to progressive iron accumulation over time.
When the body's capacity to store iron in the form of ferritin and hemosiderin is exceeded, excess iron can deposit in tissues, causing damage and a variety of health issues, including liver damage, bronze diabetes, and joint pain.
