NEET BIOLOGY

Detailed explanation-1: -The human body is inhabited by millions of tiny living organisms, which, all together, are called the human microbiota. Bacteria are microbes found on the skin, in the nose, mouth, and especially in the gut. We acquire these bacteria during birth and the first years of life, and they live with us throughout our lives.

Detailed explanation-2: -The human body contains trillions of microorganisms-outnumbering human cells by 10 to 1. Because of their small size, however, microorganisms make up only about 1 to 3 percent of the body’s mass (in a 200-pound adult, that’s 2 to 6 pounds of bacteria), but play a vital role in human health.

Detailed explanation-3: -Your gut is home to most of the microbes in your body, but your skin, mouth, lungs, and genitalia also harbour diverse populations. And as research continues into body biomes, it should reveal answers about how these microorganisms are promoting health or even disease.

Detailed explanation-4: -LOUIS (US)-Just about every bit of the human body is covered in microbes-10, 000 species-and most are friendly, according to a new census. Microbes help the body digest food, strengthen the immune system, and ward off dangerous pathogens.
