The Neck: A Vital and Complex Structure
The neck serves as a crucial conduit for many essential functions in the body, handling the transportation of air to the lungs, food to the stomach, and blood to the brain. This region is packed with vital structures, including the esophagus, trachea, and various crucial glands. Approximately 3,000 gallons of fluid and air flow through our neck daily, making it remarkable in terms of both volume and efficiency. However, this complex anatomy also creates vulnerabilities, as the arrangement of these structures makes the neck susceptible to injuries and ailments.
