The six-sided, very cool and highly complex structure below ↓ is a section of the hepatic lobule (at the microscopic level). It represents a building block of the liver that includes (at all the edges) blood and bile collecting vessels called portal triads: a portal artery (red), portal vein (blue) and bile duct (green).
I isolate and detail a lobule of the liver into the Portrait of Carolyn because I want to know where Kupffer cells hang out. They’re the smallest and brightest orange (in my ↑ study) circular forms in the sinusoids (blue central lines). Kupffer cells work to remove debris (bacteria and their product) and worn out blood cells from blood before returning it back to the heart.
And speaking of bacteria, this portrait study is the first to include microbes (archaea, bacteria, fungi, protists and viruses).
The study of these invisible-to-the-eye life forms include a language I might never grasp. Take the word Firmicutes (firmus, strong and cutis, skin), a playful word that basically means a division or category of bacteria. Firmacutes, like the Streptococcus below, are labeled gram-positive. This sounds like a good thing, doesn’t it? (I have an urge here to remind you that I am an artist not a scientist.)
If I had to rate the status of the relationship between human and microbes, I say…It’s complicated!
I continue to learn about microbes and the human microbiome. I’ve become curious about cancer causing pathogens. I look for more info on viruses in particular.
While Carolyn’s diagnosis of breast cancer is the impetus for the drawing, it’s not necessarily the focal point. A whole biological system/environment is the focus of the study.
Good time to mention the composition also includes intestinal epithelium cells ↓ that form the lining of the small and large intestines. The lining absorbs beneficial matter into the body as well as restricting harmful substances.
Over Spring Break, Carolyn and I drive to San Diego to pick up her artwork from an exhibition. Would I like to visit a tourist site? She asks while describing a stone house with a tower. Off of Interstate 8 we pull into Desert View Tower.
It feels good to move around, we hike an area of rocks and eventually make our way to the building. We climb a spiral staircase leading to a tower where we experience the view of wide open landscape. There’s a bronze bell up there too, which I photograph for no particular reason, except that I like bronze bells ( I own 2 of them).
Back in the studio I recall a conversation:
I’ve meant to tell you something. I think you’ll like this! Carolyn says. She tells me about a brass bell she’d rang at the cancer center that marked the end of her radiation treatment (and maybe the beginning of something new). It’s a tradition that all patients celebrate, she explains. I’d never heard of it. Was Brian with you? She nods and says Yes!
The work continues…connecting the parts.
