The human gut contains a host of life forms with their own genes that make up our gut microbiome. Over 10 trillion microorganisms live inside human intestines, with some recent estimates putting the number as high as 39 trillion. That means people have more microbes in their large intestine than human cells throughout their body. The human gut is also home to a sophisticated network of over 100 million neurons , which many experts refer to as the body’s “second brain.”
