why are structures not removed by natural selection?
Vestigial structures do not harm the organism. Nature selects against only harmful traits.
How are vestigial structures not removed by natural selection?
Yes, because vestigial structures can be harmful. For example, some humans are now born without an appendix which ensures they will not be killed via appendicitis. Having a smaller expression of a vestigial structure, like having a smaller appendix, saves on the energy wasted in maintaining an unneeded structure.
Within which structures in humans are bacteria and dead cells removed from lymph?

How do disease affect natural selection?
Diseases are an agent of selection. Exposed animals that survive the disease process are the ones that live to reproduce. Individuals that succumb are removed from the gene pool. The mechanism of survival could be a more robust immune system or mutation(s) that is/are inherently immune for reasons other than immune response.
