Do our intestines contain germs?
Yes, our intestines contain germs. Germs aren't all bad—in fact, some are helpful. For example, the common bacterium E. coli can be found in our intestines, and it helps us digest green vegetables and beans (also making gases). These same bacteria also make vitamin K, which causes blood to clot

Bacteria are single-celled organisms that have the ability to feed themselves and to reproduce. They are found everywhere, including the air, water, and soil. They divide and multiply very quickly, which means that one cell can become 1 million cells in just a few hours. Viruses are microorganisms tRead more
Bacteria are single-celled organisms that have the ability to feed themselves and to reproduce. They are found everywhere, including the air, water, and soil. They divide and multiply very quickly, which means that one cell can become 1 million cells in just a few hours. Viruses are microorganisms that are smaller than bacteria, but they cannot grow or reproduce without the help of a separate living cell. Once a virus gets inside your body, it attaches itself to a healthy cell and uses the cell’s nucleus to reproduce itself.

The immune system protects the human body against germs, which are microorganisms that cause sickness and disease. There are four major types of germs— harmful bacteria (pathogens), viruses, fungi, and protozoa. This defense system begins with the skin, which stops germs from getting into your bloodRead more
The immune system protects the human body against germs, which are microorganisms that cause sickness and disease. There are four major types of germs— harmful bacteria (pathogens), viruses, fungi, and protozoa. This defense system begins with the skin, which stops germs from getting into your blood or tissues. If germs get into your body, for example through your nose or mouth, white blood cells called phagocytes and lymphocytes attack them. Phagocytes scout out and destroy invaders, and long-living lymphocytes remember the invaders and release chemicals called antibodies to make the body resistant, or immune, to them. White blood cells live in the bloodstream, lymphatic system, and spleen.
The lymphatic system (or lymph system, for short) is a far-reaching network that extends throughout your entire body. A clear liquid called lymph runs throughout the system, washing the body’s cells with nutrients and water and detecting and removing pathogens. Lymph is filtered through the lymph nodes and then passes into the body’s bloodstream.

Your skin is a wonderful protective barrier that prevents many of the disease-causing germs that you run into each day from entering your body. Only when you have an opening in your skin—like a cut or a scrape—are germs likely to enter there. Most germs enter through your mouth and nose, making theiRead more
Your skin is a wonderful protective barrier that prevents many of the disease-causing germs that you run into each day from entering your body. Only when you have an opening in your skin—like a cut or a scrape—are germs likely to enter there. Most germs enter through your mouth and nose, making their way farther into your body through your respiratory or digestive tracts. But even then, certain chemicals in body tissues and fluids keep many harmful germs from causing problems. When an infection does begin—with the germs multiplying inside your body—your immune systemleaps into action to get rid of the foreign organisms. Your white blood cells produce special substances called antibodies that attack and destroy the invaders, helping you to recover.
See lessWhy do I get sick?
When you get sick, part or all of your body is not working as it should. The cause of sickness can come from inside your body or from the outside world. Diseases that start on the inside are usually inherited in the genes that you receive from your parents, which make up the master plan that determiRead more
When you get sick, part or all of your body is not working as it should. The cause of sickness can come from inside your body or from the outside world. Diseases that start on the inside are usually inherited in the genes that you receive from your parents, which make up the master plan that determines how your body will grow and run. Abnormal development or functioning of different body systems is the cause of many chronic diseases.
Things in the outside world can cause sickness too. Poisons in the environment can cause illnesses in people. Not eating the right foods, with their important nutrients, can also cause diseases. But the most common cause of sickness from the outside world is infectious agents. These agents are usually microscopic organisms (living things so small that they can only be seen with the help of microscopes) such as bacteria and viruses, commonly referred to as germs. Bacteria and viruses and other microscopic organisms live in the air, water, and soil that make up our world. They are on the things and people we touch and in the food we eat. Many of them are beneficial: bacteria are needed to make cheese, some bacteria help vegetables grow, and some bacteria clean the environment and enrich the soil by feeding on dead plants and animals. But there are other microscopic organisms that invade the bodies of plants and animals—and people—and cause diseases.
