Which of the following is NOT a function of the cardiovascular system?

• A. maintains homeostasis
• B. regulates pH levels
• C. stores nutrients
• D. transports oxygenated blood from lungs to rest of body

Answer: (C)

The cardiovascular system is all about circulation—moving blood to keep tissues nourished, wastes removed, and the body's internal environment stable. It helps maintain homeostasis by delivering oxygen and nutrients to cells and by carrying carbon dioxide and other wastes away for elimination. It also supports pH balance by transporting gases and buffers through the blood, influencing acid-base status as the lungs and kidneys work with the circulatory system. However, storing nutrients is not a function of the cardiovascular system. Nutrients are stored in tissues like the liver, muscle, and adipose tissue, while the blood primarily serves as the transport medium. Transporting oxygenated blood from the lungs to the rest of the body is indeed a key function, as the heart pumps oxygen-rich blood to tissues throughout the body.
