Step 1 : Introduction to the question "3. Your acupuncturist starts talking to you about your body's meridian lines. You ask him what they are. Which of the following would be his most likely response?"
...1. They're a citrus fruit similar to an orange 2. They are energy channels linked to your body's organs and systems 3. They are a dark brown plant pigment 4. They're reed organs where a suction bellows draws in air through the reeds OK granted, if your practitioner was a sarcastic doctor he'd probably use any of the other answers but the truth is meridians are invisible lines that allow the flow of energy through your body. There are 12 main and eight 'extra' meridians. Your main acupuncture points exist on the 12 main lines and two of the 'extra' channels. In traditional Chinese medicine (TCM) these exist within a balance of 'yin' and 'yang'. Your 'yin' organs are solid, such as your liver, and the 'yin' life force is Blood. In TCM Blood is written with a capital 'B' as it is linked to but not identified as 'physical' blood. The 'yang' organs are hollows, for example, your intestines and the 'yang' force is your 'qi' which translates to vital energy.
