Final answer:
The liver is a good control for iron because it stores iron in the form of ferritin or hemosiderin, and it also plays a key role in iron metabolism.
Step-by-step explanation:
The tissue that is a good control for iron is the liver (Answer A). The liver plays a crucial role in the storage and metabolism of iron. The iron contained in the heme portion of hemoglobin can be stored in the liver in the form of ferritin or hemosiderin. Moreover, the liver is a central site for iron recycling and homeostasis. In cases of siderosis, which is excessive iron deposition, the liver is primarily affected due to its significant role in iron storage and metabolism. Therefore, the liver is the appropriate tissue to examine when assessing iron levels or storage in the body.
The type of tissue that is a good control for iron is the liver.
Iron is stored in the liver in the form of ferritin and hemosiderin. The liver acts as a storage site for iron and releases it when needed in the body.
Other tissues like the lung, muscle, and skin do not have a significant role in the storage and regulation of iron.
