When examining the microbiome of the human intestine, you would expect to find how many bacterial species present?
a. one
b. three
c. hundreds
d. thousands

Verified step by step guidance

1. Understand that the human intestine is a complex environment that supports a diverse microbiome.
2. Recognize that the microbiome consists of a wide variety of bacterial species, each playing different roles in digestion, immunity, and overall health.
3. Consider the scale of diversity typically found in microbiomes, especially in environments like the human gut.
4. Recall that scientific studies have shown that the human gut microbiome is composed of a large number of bacterial species.
5. Conclude that the number of bacterial species in the human intestine is likely to be in the range of hundreds to thousands, based on scientific research.

Key Concepts

Human Microbiome

The human microbiome refers to the diverse community of microorganisms, including bacteria, fungi, and viruses, that inhabit various parts of the body, particularly the gut. This complex ecosystem plays a crucial role in digestion, metabolism, and immune function, and its composition can vary significantly between individuals.

Bacterial Diversity

Bacterial diversity in the human intestine is characterized by the presence of a vast number of different bacterial species. Research indicates that the gut microbiome can contain hundreds to thousands of distinct bacterial species, which contribute to the overall health and functionality of the digestive system.

Microbiome Functionality

The functionality of the microbiome is essential for maintaining human health, as it aids in nutrient absorption, synthesizes vitamins, and protects against pathogens. A diverse microbiome is generally associated with better health outcomes, while a less diverse microbiome can lead to various health issues, including gastrointestinal disorders.
