What does the immune system protect the body against?
Rudik [331]
The immune system protects your child's body from outside invaders, such as bacteria, viruses, fungi, and toxins (chemicals produced by microbes). It is made up of different organs, cells, and proteins that work together.

Anatomy of the immune system

There are two main parts of the immune system:

The innate immune system, which you are born with.

The adaptive immune system, which you develop when your body is exposed to microbes or chemicals released by microbes.

These two immune systems work together.

The innate immune system

This is your child's rapid response system. It patrols your child’s body and is the first to respond when it finds an invader. The innate immune system is inherited and is active from the moment your child is born. When this system recognizes an invader, it goes into action immediately. The cells of this immune system surround and engulf the invader. The invader is killed inside the immune system cells. These cells are called phagocytes.

The acquired immune system

The acquired immune system, with help from the innate system, produces cells (antibodies) to protect your body from a specific invader. These antibodies are developed by cells called B lymphocytes after the body has been exposed to the invader. The antibodies stay in your child's body. It can take several days for antibodies to develop. But after the first exposure, the immune system will recognize the invader and defend against it. The acquired immune system changes throughout your child's life. Immunizations train your child's immune system to make antibodies to protect him or her from harmful diseases.

The cells of both parts of the immune system are made in various organs of the body, including:

Adenoids. Two glands located at the back of the nasal passage.

Bone marrow. The soft, spongy tissue found in bone cavities.

Lymph nodes. Small organs shaped like beans, which are located throughout the body and connect via the lymphatic vessels.

Lymphatic vessels. A network of channels throughout the body that carries lymphocytes to the lymphoid organs and bloodstream.

Peyer's patches. Lymphoid tissue in the small intestine.

Spleen. A fist-sized organ located in the abdominal cavity.

Thymus. Two lobes that join in front of the trachea behind the breastbone.

Tonsils. Two oval masses in the back of the throat.

How do antibiotics help fight infections?

Antibiotics can be used to help your child's immune system fight infections by bacteria. However, antibiotics don’t work for infections caused by viruses. Antibiotics were developed to kill or disable specific bacteria. That means that an antibiotic that works for a skin infection may not work to cure diarrhea caused by bacteria. Using antibiotics for viral infections or using the wrong antibiotic to treat a bacterial infection can help bacteria become resistant to the antibiotic so it won't work as well in the future. It is important that antibiotics are taken as prescribed and for the right amount of time. If antibiotics are stopped early, the bacteria may develop a resistance to the antibiotics and the infection may come back again.

Note: Most colds and acute bronchitis infections will not respond to antibiotics. You can help decrease the spread of more aggressive bacteria by not asking your child’s healthcare provider for antibiotics in these

6. What are proglottids? What is the scolex?
Nataliya [291]

Explanation:

Proglottids are segments in cestodes that contain bot the male and female reproductive organs. These segments go ahead to make eggs and then dettach form the worm. They are excreted and become agents of infection on the next hoist. Proglittids formed near the neck of the worm are immature while those at the tail end are literally bags of mature eggs.

The scolex is the head of the worm that is attached to the host. It is also the part that ‘sucks’ nutrients from the host. It has hooks that it uses to anchor itself in the host. In some species, rather than hooks, there are suction-cups that use suction for anchorage.
