Verified step by step guidance

Step 1: Begin by understanding what constitutes a major organ system in the human body. Major organ systems are groups of organs that work together to perform specific functions essential for maintaining homeostasis and overall health.

Step 2: Review the options provided in the problem. The Digestive system, Circulatory system, and Respiratory system are all major organ systems in the human body. Each of these systems has distinct roles, such as nutrient absorption, blood circulation, and gas exchange, respectively.

Step 3: Eliminate the Photosynthetic system as it is not a system found in humans. Photosynthesis is a process specific to plants and some microorganisms, not humans.

Step 4: Confirm the correct answers by recalling the functions of the Digestive system (processing food and absorbing nutrients), Circulatory system (transporting blood and oxygen), and Respiratory system (facilitating breathing and gas exchange). These are all critical to human survival.

Step 5: Conclude that the major organ systems listed in the problem are the Digestive system, Circulatory system, and Respiratory system, while the Photosynthetic system is not relevant to human anatomy and physiology.
