Anterior cervical soft tissue procedures affect the patient\u2019s ability to respond to an upper respiratory tract infection through their effect on which system?

• A. Lymphatic drainage
• B. Circulatory flow to the lungs
• C. Oxygen transport
• D. Nasal mucosa

Answer: (A)

Lymphatic drainage is the system most involved. The lymphatic network of the head and neck clears interstitial fluid and transports immune cells and antigens from mucosal surfaces to regional lymph nodes where the immune response is activated. When anterior cervical soft tissues are involved, lymphatic flow can be altered, diminishing efficient drainage and immune cell trafficking from the upper airway. This can weaken the body’s ability to respond to an upper respiratory tract infection. Circulatory flow to the lungs and oxygen transport relate to blood flow and gas exchange, not the specific immune clearance pathway. Nasal mucosa is part of the barrier and local defense, but mounting a systemic immune response to aURI relies more on lymphatic drainage and lymph node activation.
