The human body is unable to store most water-soluble vitamins for prolonged periods, making their regular dietary intake essential. The primary organ responsible for filtering and expelling any surplus of these vitamins is a crucial part of our urinary system, ensuring homeostasis and preventing potential toxicity from over-supplementation.

Did you know the human digestive tract is a muscular tube approximately 30 feet long? This vast network is the core of what is the system involved in the process of nutrition, working with other major systems to convert the food you eat into the energy your body needs to function.

Ostriches, like all birds, have evolved a highly efficient method for dealing with nitrogenous waste, producing uric acid instead of urea. This physiological adaptation allows them to conserve significant amounts of water, an essential trait for an animal that thrives in arid environments. But why do ostriches have uric acid, and what does this mean for their bodily functions?

As the second most abundant trace element in the human body, zinc levels are tightly regulated through a process called homeostasis. Since the body does not have a dedicated storage compartment for excess amounts, an intricate system ensures proper absorption and excretion. This mechanism explains precisely how does zinc exit the body, preventing accumulation and potential toxicity.
