Well this is rather weird.
There are some things that could be improved but it looks nice. Ignoring the whole “Alveoli stasis” stuff. Oh and yes these are the same fellas from that one Sleeper Train drawing I made about month ago.
Oh and yea, this was made with the Waterpen brush lol.

Capturing Lung Development
Our lungs develop during all three trimesters of pregnancy, so for babies born prematurely, the lungs may not have had enough time to form correctly. As a result, they may be susceptible to disease. This is particularly true for the alveoli – tiny sacs at the end of the branches in the lungs where gas exchange occurs. It‘s difficult to study how alveoli form in developing foetuses, so researchers have devised a new way to understand more about the steps involved in alveoli maturation and help find ways to better treat conditions. Creating an organoid – a ‘mini developing lung’ grown in the lab, now enables tracking of how and when alveoli form and the genes and proteins influencing the process to be pinpointed. As if you were moving through them, this video shows an example of what these organoids look like and the structures they mimic (branches and alveoli in various colours).

During cereal endosperm development, the triploid primary endosperm nucleus undergoes a series of mitotic divisions without cytokinesis, and the nuclei migrate to the periphery of the central cell, which also contains a large central vacuole (Figure 21.26, see parts A-D). As in the Arabidopsis coenocyte, each of nuclei is surrounded by radially arranged microtubules (see Figure 21.26E). Anticlinal walls form initially between adjacent nuclei, resulting in the tubelike alveolar cells, with the open end pointing toward the central vacuole (see Figure 21.26F). (...) The innermost layer of daughter cells remains alveolar in structure, and continues to divide periclinally until cellularization is complete (see Figure 21.26G and H). The most important source of starchy endosperm cells is the interior cells of the cell files that are present at the completion of endosperm cellularization (see Figure 21.26H).
