Beverages
[Inside a single frame, liquid pouring out of a glass through mouth, the esophagus, and to the stomach is shown. However the surrounding bodies like the organs or the glass are not pictured, are only defined by the shape of the liquid, and must be imagined. Further two small parts within or near the invisible stomach with no visible connection to the rest are also wetted.] [Caption below the frame:] It freaks me out to imagine what a beverage is shaped like when I’m in the middle of drinking it.

It is frequently stated that liquids take the shape of their container. While being poured, though, what that "shape" is is open to interpretation. The comic shows the "shape" of a liquid being "poured" down someone's throat (in the process of drinking) and highlights how unsettling this may look without any visible guidance for its flow. While the flow of the beverage wets every parts downwards, it looks as if the stomach is only partially filled, because the process of drinking is still underway and the glass is still half full, and because the contents of the glass would not be enough to fill the stomach in any case.  Therefore the shape of the liquid in the stomach area would not correspond to the full shape of the stomach, and there could be additional blobs of liquid where it might have splashed and detached from the main liquid mass, such as depicted by the two little disconnected pieces to the right of the stomach area.
The title text expands on this, encouraging the reader to think of the liquid travelling through the entire human digestive tract and to consider that it will eventually dilute through the entire human body ("shaped like me"), with what doesn't leaving the body to pass through the water treatment process ("some pipes and tanks"), and that finally most particles from any ingested liquid will mix with all water on Earth ("all of Earth's oceans"). But by the time a beverage is diluted enough to take the shape of Earth's oceans, the molecules will be so dispersed that the beverage effectively becomes invisible.
Note: A barium swallow is a medical procedure that actually studies the shape of a liquid when it is being swallowed, to diagnose problems in the esophagus and other structures.
