This functional tissue unit (FTU) illustration was created from anatomical structures and cell types listed in the ASCT+B Table [Liver v1.1](https://doi.org/10.48539/HBM456.SLDZ.399). Multiple histology atlases, especially “Netter’s Essential Histology with Correlated Histopathology” (William K. Ovalle and Patrick C. Nahirney, 2021), “Junqueira’s Basic Histology Text & Atlas” (Anthony L. Mescher, 2021), “Human Microscopic Anatomy” (R.V. Krstić, 1994), and “Histology: A Text and Atlas” (Michael H. Ross, et al., 2003) were referenced. Measurements were taken from [(Hall et al. 2017)](https://doi.org/10.1038/srep40977).
