What is an example of a function performed by organs?

Organs are specialized structures in the body that carry out specific functions essential for maintaining homeostasis and overall health. In the context provided, each of the mentioned functions—pumping blood through a vascular system, producing reproductive cells, and storing nutrients—demonstrates the various roles that different organs play.

Pumping blood is a function performed by the heart, which is a critical organ in the circulatory system. This function is vital for delivering oxygen and nutrients to tissues and removing waste products.

Producing reproductive cells is a function of the reproductive organs, such as the ovaries and testes. These organs are essential for sexual reproduction and the continuation of species.

Storing nutrients relates to organs such as the liver, which plays a significant role in metabolizing and storing carbohydrates, fats, and proteins for energy use and other bodily functions.

Since each of these functions is a fundamental role performed by specific organs, the option that states all are examples of organ functions is correct. This highlights the diverse capabilities of organs in supporting life processes.
