Organ Structures
This bean-shaped structure acts as a tiny filter to trap bacteria and viruses, and it often swells up when you are sick.
a lymph node
The main job of this largest organ of the body is to act as a wall to keep pathogens from entering in the first place.
What is skin
This is the general scientific term for any living thing (like a bacteria, virus, or fungus) that causes a disease.
Pathogen or germ
This sticky fluid found in your nose and throat traps dust and pathogens before they can get deeper into your body.
What is Mucus
The immune system produces these Y-shaped proteins that latch onto specific pathogens to mark them for destruction.
What are antibodies
This soft tissue is found inside the hollow center of your bones,where all blood cells are made.
What is bone marrow
These specialized cells travel through your blood vessels to hunt down and destroy invaders.
what is white blood cells
a medical shot that trains your immune system to fight a specific virus without actually making you sick.
What is vaccine
If pathogens break through your skin, this "second line" response causes the area to swell, turn red, and heat up to bring in help.
What is inflammation
The body deliberately raises its internal temperature to create this condition, which slows down the reproduction of viruses and bacteria.
What is fever
Located in the upper left side of your abdomen,
What is spleen
This organ destroys worn-out blood cells and keeps a backup supply of platelets and white blood cells ready.
What is spleen
This happens when your immune system overreacts to a harmless substance, like pollen, peanuts,
Allergic reaction
This line of defense is highly specific, meaning it creates custom weapons to target one exact type of germ.
What is the third line of defense? (Accept: "Adaptive immunity")
This process causes redness, swelling, and heat around a cut, bringing more blood and white cells to the injury site to fix it.
What is inflammatory
This small, butterfly-shaped gland sits right behind your Chest
What is thymus
The primary job of the thymus gland is to train these specific types of white blood cells so they can fight infections.
What is T cells
What number did i say multiple times in my slides
2
These tiny, hair-like structures in your respiratory tract sweep mucus and trapped germs up and out of your airways.
What are cilia
This is the specific action where a white blood cell engulfs, "eats," and digests a pathogen.
What is phagocytosis
These two rings of lymphatic tissue sit at the back of your throat
What are tonsils
vessels drains excess fluid from your body tissues, filters it, and returns it safely to your bloodstream.
Lymphatic system
This type of illness occurs when the immune system gets confused and mistakenly attacks the body's own healthy cells.
What is an autoimmune disease
Found in your stomach, this highly acidic liquid destroys most of the pathogens that manage to enter through the food you eat.
What is stomach acid
The immune system creates these specific cells after an infection so that if the same germ returns years later, you won't get sick again.
What is memory cells
