The correct answer is the vascular system, as it plays a crucial role in delivering liquid nutritives, such as blood, throughout the body. The vascular system is composed of a network of blood vessels, including arteries, veins, and capillaries, which transport oxygen, nutrients, hormones, and waste products to and from cells. This continuous flow is essential for maintaining overall health and supporting cellular functions.

Other systems listed have different primary functions. The immune system is focused on defending the body against pathogens and foreign invaders, while the nervous system is responsible for coordinating bodily functions through electrical signals and communication. The endocrine system regulates bodily functions via hormones but does not directly transport liquid nutritives. Thus, the vascular system is uniquely equipped to manage the distribution of essential nutrients throughout the body.
