Question

How do the immune system and digestive system work together?​

Answer 1

I know that a major part of the immune system is located in the digestive system. Also your gut micro biome shapes the immune system.

Answer 2

The immune system works with the digestive tract to help protect you from infection by these potential invaders. Your immune system also depends upon cells to kill invading organisms, and chemicals that don't require the involvement of cells at all, but which are simply toxic to bacteria and viruses. Acid in the stomach does the same thing.
