Nature (biological structures)

In biological terms, "nature" refers to the diverse structures and systems within living organisms, such as cells, tissues, organs, and entire body parts. These structures are organized in ways that enable life functions like movement, growth, reproduction, and response to the environment. For example, the heart's muscular structure pumps blood, while the brain's complex network processes information. These biological structures are shaped by genetics and evolution, optimized over time to support survival and adaptation in their environments. Together, they form the intricate and functional architecture that sustains life.
