Most people died from infections after surgery.

Everyone open your mouth

You just sucked in an invader.

Every second microbes are trying to kill us by attacking our cells.

Without an immune systems to protect us from the thousand of micro invaders out there, you would certainly die.

H.G. Wells wrote: War of the Worlds.
Does anyone know how the invaders were stopped? Copyright © 2010 Ryan P. Murphy

The alien invaders were too powerful to be destroyed by our weapons
The alien invaders were too powerful to be destroyed by our weapons. They were killed by infectious diseases because they did not evolve an immunity to earth’s diseases.

New Area of Focus: Your Immune System.

The Immune System is all over the place

Immune system: A system that protects the body from diseases.

The system includes…

The system includes… Special cells

The system includes… Special cells Proteins

The system includes… Special cells Proteins Antibodies

The system includes… Special cells Proteins Tissues

The system includes… Special cells Proteins Tissues Lymphoid Tissues

First Line of Defense.

Skin prevents disease from entering the body.

Where are there holes in the wall?

Answer! Where are there holes in the wall?

Mucus is another defense mechanism of the human body.
They trap and remove these invaders before the can reach their target cells. Cilia move the invaders to be disposed.

Your nose produces close to a liter of mucous a day.
Most gets swept into the esophagus by tiny hairs called cilia in your nasal cavity.

Salvia is also loaded with disease killing chemicals.

One of the biggest achievements of the immune system is it’s ability to determine friend from foe.

The Bodies 2nd Line of Defense

The body also rushes blood loaded with protecting cells to infected areas. (Swelling)

The inflammatory response: Damaged cells release chemicals.
These chemicals cause blood vessels to leak fluid into the tissues, causing swelling. This helps isolate the foreign substance from further contact with body tissues.

Anaphylaxis is a severe allergic reaction that occurs rapidly and causes a life-threatening response involving the whole body.

Anaphylaxis is a severe allergic reaction that occurs rapidly and causes a life-threatening response involving the whole body. This reaction can lead to difficulty breathing, shock, and ultimately death if untreated.

Epinephrine injection is used to treat life-threatening allergic reactions caused by insect bites, foods, medications, latex, and other causes.

Epinephrine injection is used to treat life-threatening allergic reactions caused by insect bites, foods, medications, latex, and other causes. Please see a doctor if you believe you are severely allergic to any of the above.

The body also has another defense mechanism called and interferon response.

Cells produce a substance that interferes with the ability of viruses to reproduce.

Day One. You wake up, and your entire body aches.

Please create a drawing in your journal in a step by step process on the next slide..

Video Link! Hand drawing the Immune System.
Now try and label your picture with some terms, chemical signals, and arrows as best you can. It’s a complicated system .

Don’t Freak! This was difficult, instead of stressing out, let’s record three things we can learn from our crazy diagram. Cells can give off chemical signals Cells can tell cells to die off There are many lines of defense.
