Final answer:
Organs like the brain or kidney are not considered separate living beings, but are part of a larger organism that functions as a whole. Humans are classified as animals, and each organ has a specialized function within the organ system.
Step-by-step explanation:
While organs like the brain or kidney are essential components of living beings, they are not considered separate living beings themselves. They are part of a larger organism, such as a human, and work together with other organs to carry out specific functions. For example, the brain is responsible for processing information and controlling body functions, while the kidney filters waste from the blood.
In the classification of living organisms, humans are classified as animals, which are multicellular organisms capable of breathing, moving, ingesting and excreting food, and reproducing sexually. Each organ within the human body has its own specialized function, but they are all interconnected within the organ systems that make up the organism as a whole.
