Which of the following represents the correct levels of organization in the body?

• A. Cell, Organ, Organism, Tissue
• B. Cell, Tissue, Organ, Organ System
• C. Tissue, Organ, Organ System, Cell
• D. Organism, Cell, Tissue, Organ

Answer: (B)

The correct sequence of levels of organization in the body is Cell, Tissue, Organ, Organ System. At the most fundamental level, cells are the basic unit of life, where various biological processes occur. When similar cells come together, they form a tissue, which is a group of cells working together to perform a specific function. Multiple tissues then combine to create an organ, which carries out complex functions necessary for the body's operation. Finally, groups of organs collaborate to form an organ system, which serves broader physiological roles within the organism. This hierarchical structure is crucial for understanding how biological systems operate and are organized, reflecting the increasing complexity from individual cells to complete organisms.
