D.
a heart, arteries, and veins all working together

D.

a heart, arteries, and veins all working together

The correct answer is D. A heart, arteries, and veins all working together is an example of an organ system.

The correct answer is option D. A heart, arteries, and veins all working together form an example of an organ system. The heart pumps blood, and the arteries and veins transport this blood throughout the body, ensuring that oxygen and nutrients reach the cells and waste products are removed. This coordination between different organs is what defines an organ system.

To get the answer, you would need basic knowledge of human anatomy and physiology. Understanding the functions of different organs and how they work together to perform specific tasks is essential in identifying examples of organ systems. It is helpful to study biology or anatomy textbooks, take related courses, or explore reliable online resources to gain this knowledge.
