What is a group of organs sharing a general function called?

A group of organs that share a common general function is referred to as a system. In the context of human anatomy and physiology, systems consist of various organs working together to perform complex functions that are crucial for maintaining the body's overall health and homeostasis. An example would be the cardiovascular system, which includes the heart, blood vessels, and blood, all cooperating to circulate oxygen and nutrients throughout the body.

The other choices represent different biological levels of organization. A cell is the basic unit of life; tissues are groups of similar cells that perform a specific function; and an organism refers to a complete living body that encompasses multiple systems, including various organs and tissues. This structurally hierarchical classification helps in understanding how biological systems interact and function efficiently.
