Vitamin A is primarily stored in which organ of the body?

Vitamin A is primarily stored in the liver. This organ plays a crucial role in the metabolism and storage of various nutrients, including fat-soluble vitamins like Vitamin A. In the liver, Vitamin A is stored in the form of retinol and can be mobilized into the bloodstream when needed to support various physiological functions, such as vision, immune response, and skin health. The liver's capacity for storage and release helps maintain appropriate levels of Vitamin A in the body, ensuring that it is sufficiently available when required.

Other organs mentioned, such as the kidney, spleen, and intestine, do not serve the primary function of storing Vitamin A. The kidney is more involved in the filtration and excretion of waste products, while the spleen plays a role in the immune response and the filtering of blood. The intestine is essential for the absorption of nutrients, including vitamins, but does not function as a storage site for Vitamin A. This distinction makes the liver the correct answer for the primary organ involved in the storage of Vitamin A.
