What are the eight body systems represented by the acronym L-U-R-D-C-H-I-N?

The correct answer identifies the eight body systems represented by the acronym L-U-R-D-C-H-I-N as Locomotor, Urogenital, Respiratory, Digestive, Cardiovascular, Hormonal, Immune, and Nervous. Each of these systems plays a critical role in maintaining the overall health and function of the human body, contributing to physical activity, reproductive functions, gas exchange, nutrient processing, blood circulation, hormonal regulation, immune response, and nerve signaling.

For instance, the Locomotor system involves bones and muscles that facilitate movement, while the Respiratory system is essential for bringing oxygen into the body and expelling carbon dioxide. The Cardiovascular system ensures that blood—and thus nutrients and oxygen—are transported throughout the body. The Immune system is vital for protecting the body from pathogens.

This option effectively encapsulates the relevant systems as they relate to the study of yoga and well-being. Understanding these systems helps yoga instructors appreciate how yoga poses and practices can support and benefit these various bodily functions, promoting overall health.

In contrast, the other options either mislabel specific systems or use terms that are less commonly recognized in anatomical vocabulary. For example, the use of "Reparatory" instead of "Respiratory" or "
