Understanding Organ Systems and Cells

The video explains the complexity of organisms, starting from atoms and molecules, which form organelles. These organelles perform specific cellular processes, leading to the formation of cells, the basic units of life. Cells group into tissues, which form organs, and organs work together in organ systems. The video emphasizes the increasing complexity from atoms to a complete organism.
