Cells are the building blocks of the body. Each cell performs specific tasks like respiration, protein synthesis or nutrient transport. Similar cells form tissues, which group into organs like the heart or lungs. These organs work together in systems to keep the body functioning. Thus, cells coordinate to perform all life activities like breathing, digestion, movement and reproduction.
