Final answer:
The question misinterprets the Hand-Yangming channel as related to planetary channels, when it is actually a concept from Chinese medicine referring to a meridian within the human body. It does not correlate with geological features like those on Mars, which contradicts the idea of visible 'canals' once theorized by Percival Lowell.
Step-by-step explanation:
The question pertaining to the Hand-Yangming channel seems to be centered around the concept of traditional Chinese medicine rather than astronomy or planetary science. The confusion arises from the use of the term 'channel,' which in the context of Chinese medicine refers to meridians or pathways within the body through which Qi (energy) flows. The Hand-Yangming channel, also known as the Large Intestine meridian, follows a specific pathway on the body and not through environmental or geological constructs such as 'runoff channels' or 'outflow channels' as might be confused with the channels observed or hypothesized on planets like Mars. The 'canals' mentioned appear to refer to the now-debunked theory that Mars had visible man-made canals, a theory propounded by Percival Lowell in the late 19th and early 20th centuries.
As there is a misunderstanding in the question, is not directly applicable here. However, for clarity purposes, the Hand-Yangming channel does not pass through any geographical features, as it is a concept that belongs to the human body's meridian system in traditional Chinese medicine, not related to physical geography or planetary channels.
