Explanation:

Analyze the question requirements

The question asks to identify the organ systems that sustain the life of an individual human. This is a key distinction in anatomy and physiology: while some systems are essential for the survival of the species, others are strictly required to keep an individual organism alive.

Evaluate each organ system

• Cardiovascular system: Transports oxygen, nutrients, and waste products. Essential for individual survival.
• Reproductive system: Responsible for producing offspring to sustain the species. An individual human can live a full life without a functioning reproductive system. Thus, it is not required to sustain the life of an individual.
• Nervous system: Regulates and coordinates body activities, including vital functions like breathing and heart rate. Essential for individual survival.
• Endocrine system: Secretes hormones that regulate metabolism, growth, and homeostasis. Essential for individual survival.
• Lymphatic system: Maintains fluid balance and houses immune cells to protect against pathogens. Essential for individual survival.
• Respiratory system: Performs gas exchange (oxygen intake and carbon dioxide removal). Essential for individual survival.

Connect to survival concepts

Using the Human Survival Needs concept, we distinguish between systems maintaining immediate homeostasis and physiological survival versus those dedicated to reproduction. All listed systems except the reproductive system are vital to maintaining the life of an individual.
