lymph vessels
nobody seems to care much about these guys, yet your arm would swell up without them — there’s just enough net fluid leak from capillaries to cause problems in the absence of another set of pipes to return that transudate to the circulatory system

fossilized compact bone
the yellow spheres are mineral deposits — not cells — that collected over the course of fossilization

acute megakaryoblastic leukemia
this subset of acute leukemia affects the megakaryoblastic lineage, which explains the multinucleation and cytoplasmic processes of these cancerous cells — in a non-pathological situation, however, pieces of mature megakaryocytes pinch off to form platelets
cancerous megakaryoblasts are also related to the pokemon, Gastly
I’d advise against catching this one though

ovarian blood river
actually it’s an endothelium-lined lumen of a blood vessel
but it looks like a river

turns out your brain is lined by gumballs…er…ependymal cells
ependyma is one of the four types of neuroglia in the central nervous system, constituting an epithelium-like layer that lines the ventricles and central canal of the spinal cord
it also produces cerebrospinal fluid (CSF)
note that in the fetus (here), ependymal cells are not ciliated

clusters of serous cells (acini) of the exocrine pancreas
the exocrine portion of the pancreas secretes digestive enzymes (tryptase, amylase, lipase, etc) while the endocrine portion produces insulin, glucagon, and other hormones that regulate metabolism

liver lobule
each roughly hexagonal lobule consists of a central vein with radiating sinusoids and hepatocytes, the cells responsible for detoxifying blood that percolates through the system

esophageal epithelium with some local bacteria
like skin, the esophagus is lined by stratified squamous epithelium
unlike skin, the esophagus is not keratinized because let’s face it — that’d be weird
