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

The function of the cardiovascular system primarily revolves around the circulation of blood throughout the body, which is crucial for delivering oxygen and nutrients to cells and facilitating the removal of waste products such as carbon dioxide. Additionally, the cardiovascular system plays a role in maintaining homeostasis and assisting in thermoregulation.

Regulating skin moisture falls outside the responsibilities of the cardiovascular system. Skin moisture primarily involves the integumentary system, where sweat glands play a key role in hydration and temperature regulation. The cardiovascular system does not directly influence skin moisture levels; rather, it may indirectly affect skin condition through blood flow and nutrient supply.

Thus, understanding the specific functions of the cardiovascular system highlights why options related to oxygen delivery, carbon dioxide removal, and nutrient distribution are accurate, whereas regulating skin moisture is not a function associated with this system.
