Depot and excretory role of a liverLet’s write!

Blood is deposited in it, and the destruction of red blood cells occurs with the formation of bilirubin from hemoglobin.

Cholesterol, bilirubin, urea, and heavy metal compounds are released into the gastrointestinal tract by the liver.

Reactive Oxygen Species (ROS) Let’s write!

Reactive Oxygen Species (ROS) is a phrase used to describe a number of reactive molecules and free radicals derived from molecular oxygen. These molecules, produced as byproducts during the mitochondrial electron transport of aerobic respiration or by oxidoreductase enzymes and metal catalyzed oxidation, have the potential to cause a number of deleterious events.

Atomic oxygen has two unpaired electrons in separate orbits in its outer electron shell. This electron structure makes oxygen susceptible to radical formation. The sequential reduction of oxygen through the addition of electrons leads to the formation of a number of ROS including: superoxide; hydrogen peroxide; hydroxyl radical; hydroxyl ion; and nitric oxide.
