1. Show a video showing how different parts of the Immune system work together to help our bodies protect and fight germs.

2. Lead a class discussion for students to consider how our immune system can be weakened by various factors.

3. Guide students as they read about and analyze data representations that show how our immune system activity is affected during winter versus summer.

4. Writing guide questions for the germology game show to connect learning about the immune system to the unit driving question.

Use the discussion in Step 1 to test students’ understanding of how different parts of the immune system work together to help our bodies protect and fight germs. To build on this key idea, have students write a summary statement on the topic they discussed in Step 1.

The handout can be used for students’ ability to identify cause and effect relationships between certain activities and their effects on our immune system as well as to analyze graphs.

Specific Vs. Non Specific Immunity

Use students’ questions and evidence-based responses to assess their developing understanding of how the immune system is negatively affected by activities and other factors in winter versus summer, which can help Why germs make us sick in winter.

To help students develop evidence-based quiz questions for a germ game show, have students survey community members about what they know and don’t know about germs and why they think people are more likely to be sick in the winter. They get sick.

When showing the video in Step 1, turn on closed captioning to support students’ literacy development and understanding of the content.

This activity builds on what students have previously learned about the immune system, focusing on how specific everyday activities support our immune system, and how people’s engagement in these activities varies seasonally. happens The four activities are eating lots of fruits and vegetables, exercise, sleep, and exposure to sunlight (which provides vitamin D). Students learn about seasonal trends through these activities by analyzing data representations, which is an authentic scientific process that students should begin developing skills during elementary school.

Additionally, systems thinking is an important exercise for students to make sense of complex phenomena. The cause and effect pathways in this activity are a basic way for students to begin to engage in systems thinking about how specific activities affect the immune system’s ability to fight germs.

Function Of Antibodies (immunoglobulins) • Microbe Online

Every day, you encounter things that can make you sick. From bacteria to viruses to fungi, the world around you is full of pathogens. Pathogens are organisms (usually microorganisms) that can cause disease. But despite all these ailments, you may be in good health.

This is thanks to your immune system, a series of defense mechanisms in your body that work 24/7 to keep you healthy. The immune system includes specialized cells, proteins, such as enzymes, and antibodies. It also includes parts of your body you might not think of as part of your immune system – like your skin!

Imagine that you cut your finger and infect the bacterial wound. Let’s take a look at the battle your body will wage to keep you healthy.

Your immune system has three levels of defense. If a pathogen passes through one level, it invades the next level.

Lymphatic Vessels: Anatomy, Function, And Treatment

The first line of defense is your innate immune system. One level of this system consists of physical barriers such as your skin and the mucosal lining of your airways. Mucous and mucosal linings produced by tears, sweat, saliva, and skin are also part of this physical barrier. These quick and simple responses can eliminate some pathogens before they have a chance to reach your tissue or blood.

For example, your skin is a physical barrier that prevents pathogens from entering the body. But if you cut the skin on your finger, bacteria will have a way to enter your body. At that point, the next level of your innate immune system will respond.

Do you know? There is a difference between an infection and a disease. An infection occurs when a microorganism invades and multiplies in your body. An infection occurs when an infection damages your cells and causes symptoms of the disease. What is the body’s second line of defense against pathogens?

The second level of the innate immune system consists of cells and proteins that attack invaders. Intrinsic defenses are nonspecific. In other words, no matter what disease your body is fighting, the same response occurs and the same cells and proteins are at work.

The Lymphatic System 2: Structure And Function Of The Lymphoid Organs

Cells called phagocytes live in your tissues and bloodstream. Macrophages and neutrophils are two types of phagocytes. Phagocytes recognize when something enters your body that doesn’t belong there and jump to work. They destroy invaders using a process called phagocytosis.

First, a macrophage recognizes and binds the invader. It then envelops it and breaks it down with the help of lysosomes. This destroys the attacker. Macrophages also sound the alarm by producing proteins called cytokines to recruit other types of white blood cells to help. These other types of white blood cells are called neutrophils, eosinophils, and basophils.

Neutrophils make up 40-70% of white blood cells (WBC). Their Main Function is to engulf and destroy invading bacteria and fungi (phagocytose). Eosinophils make up only 5% or less of WBCs. They contain toxins that can kill pathogens too large to cover it. They also release protein substances that are involved in causing inflammation.

Often, this line of defense is sufficient to resolve the infection. At the very least, it can limit the spread of infection. For example, bacteria that may enter through a cut on your finger may no longer reproduce in your body.

Macrophages: What Are They, Different Types, Function, And More

But there are some conditions that the natural immune system cannot handle. For example, there may be too many bacteria, or the bacteria may overgrow. This is when your adaptive immune response kicks in.

The third layer of your immune system consists of cells designed to get rid of specific microorganisms that have invaded your tissue.

Specialized cells called dendritic cells are the point of communication between innate and adaptive immunity. Remember macrophages? When they sound that alarm, dendritic cells are part of the crew that responds. They travel to the site of infection, where they phagocytose and break down small parts of the pathogen. They take these parts to your lymph nodes, where adaptive immunity begins.

The main cells and organs that make up the adaptive and innate parts of the immune system

Autoimmune Disease: Types, Symptoms, And More

The adaptive immune response involves two main types of specialized white blood cells called lymphocytes – B cells and T cells. B cells are found in the blood. Their main Function is to mature into cells that produce antibodies to fight antigens (foreign invaders) that enter the body. To do this, they work with T cells.

In the lymph nodes, dendritic cells search for T cells. Your body makes millions of different T cells. Each type of T cell can recognize different types of pathogens. This means that your body can withstand almost any invader, even if it has never seen it before!

In the lymph nodes, the T cells are fully mature, but they have never encountered the disease they have to fight. These cells are essentially dormant. The function of dendritic cells is to awaken and deliver them to pathogens.

Normally, T cells can eradicate a bacterial infection just days after they have been activated. At this point, your body can stop fighting, and you will start to feel better.

Do you know? The 2018 Nobel Prize in Physiology or Medicine was awarded for discoveries about how the immune system is regulated. These discoveries lead the way to immunotherapy drugs to treat skin cancer!

As you can see, your immune system is a complex system that works around the clock to keep you healthy. So the next time you feel down, just remember: there are billions of cells in your body, and all of them care about you!
