Final answer:
Our bodies are a vast network of systems all interrelated through connective tissue and sometimes referred to as a living organism. Several cells of one kind interconnect to form tissues, which combine to form organs, and several organs make up an organ system. Several systems functioning together form an organism.
Step-by-step explanation:
Our bodies are a vast network of systems all interrelated through connective tissue and sometimes referred to as a living organism. Several cells of one kind that interconnect with each other and perform a shared function form tissues. These tissues combine to form an organ, and several organs make up an organ system. Several systems that function together form an organism.
