AI Thread Summary
Macrophages play a crucial role in the immune system by engulfing debris, pathogens, and dead cells. Once they absorb this material, they break it down using enzymes. The processed components can either be expelled as waste or assimilated into the body's metabolic processes. This assimilation can contribute to functions such as respiration and protein synthesis, indicating a dual role in both waste management and nutrient recycling. In the case of apoptotic cells, their components can also be reused by neighboring cells rather than being completely flushed out, highlighting the body's ability to recycle cellular materials effectively.

I was wondering what happens to all the "debris" that is absorbed by macrophages? Do they process them to the waste system or is it possible that they can feed them to the needs of neighboring cells?

Or do these different chemical processes of eating nutrition vs getting rid of waste not mix?

Especially with one's own cells, if a multicellular's own cell dies through apoptosis, can its parts be re-used by the body or are they flushed flushed? Or both?

Thanks for any thoughts.

I am reading Nicholas Wade's book A Troublesome Inheritance. Please let's not make this thread a critique about the merits or demerits of the book. This thread is my attempt to understanding the evidence that Natural Selection in the human genome was recent and regional. On Page 103 of A Troublesome Inheritance, Wade writes the following: "The regional nature of selection was first made evident in a genomewide scan undertaken by Jonathan Pritchard, a population geneticist at the...
