Verified step by step guidance1
Step 1: Begin by identifying the primary role of the digestive system in the human body. The digestive system is responsible for processing food to extract nutrients and energy necessary for survival.
Step 2: Understand the key processes involved in digestion: ingestion, mechanical and chemical breakdown of food, absorption of nutrients, and elimination of waste. These processes highlight the system's main function.
Step 3: Compare the functions of other systems mentioned in the options. For example, filtering waste from the blood is the role of the urinary system, pumping blood is the role of the cardiovascular system, and producing hormones for growth is primarily the role of the endocrine system.
Step 4: Eliminate the incorrect options based on the functions of other systems. Focus on the option that aligns with the digestive system's role in breaking down food and absorbing nutrients.
Step 5: Conclude that the correct answer is the option describing the digestive system's main function: 'To break down food and absorb nutrients.'
