| Jul 20, 2020 at 1:16 | comment | added | practiZ | @ThePointer sinuses (sinusoids), capillaries, then veins - this is what bone marrow's microcirculation consists of. So once released into the bloodstream, mature cells follow this path to get out of bone marrow into central circulation. britannica.com/science/sinusoid | |

And I don't think veins are microcirculation either. Based on the textbook description, it seems that the author is saying that the microcirculation takes the cells back in the direction from which they came, leading out of the bone marrow; this part still needs to be addressed. | |
| Jul 16, 2020 at 0:40 | comment | added | practiZ | @ThePointer addressing your comment to the question: the developing cells are outside the sinuses, then once they mature they are released into the sinuses, meaning in the marrow microcirculation. This all happens in the marrow - inside the bone. From there, via veins that perforate the outer bone layer (compact bone), they find connection to bigger veins and systemic circulation. | |
| Jul 15, 2020 at 19:18 | comment | added | The Pointer | Yes, but you're providing a general answer to that question, rather than an answer that is within the context of my question and specifically addresses it. | |
| Jul 15, 2020 at 10:41 | comment | added | practiZ | @ThePointer your question was where the developing cells are located in respect to the bone, right? | |
| Jul 15, 2020 at 1:52 | comment | added | The Pointer | So how specifically does this clarify the point of the textbook explanation? | |
