Understanding kidney function

An overview of the kidneys

The kidneys are vital organs that play a crucial role in maintaining overall health and well-being. They are responsible for filtering waste products, excess fluids, and toxins from the bloodstream, while also regulating the levels of key substances such as electrolytes and hormones.
