Which of the following is a function of the liver highlighted by the mnemonic PUSH DoG?

• A. Storage
• B. Oxygen delivery
• C. Digestion
• D. Blood volume regulation

Answer: (A)

The function of the liver that aligns with the mnemonic PUSH DoG is storage. The liver plays a crucial role in storing various substances that are essential for the body’s functioning. It stores glycogen, which can be converted to glucose to help regulate blood sugar levels. Additionally, it holds vitamins and minerals, such as vitamins A, D, E, K, and B12, as well as iron and copper, which are vital for numerous metabolic processes. This storage function is vital for maintaining the body's energy levels and ensuring that essential nutrients are available when needed.

Oxygen delivery is primarily the role of the cardiovascular system, not the liver. Digestion, while related to the liver's function in producing bile for fat emulsification, is not a direct function the liver performs by itself. Blood volume regulation is more closely related to the kidneys’ role in fluid balance. Therefore, storage is the most accurate representation of a key hepatic function in relation to the mnemonic provided.
