Learn about the different types of diseases and their modes of transmission. Understand why blood in urine is a sign of kidney disease and the importance of vaccination in maintaining immunity. Explore the functions of the immune system and the body's defense mechanisms against pathogens.

5/5 Daily Catalyst Pg. 67 Immune System 1. I have West Nile Virus. I got the virus from a mosquito. Is this an example of a communicable or non-communicable disease and WHY? 2. Taking daily multi-vitamins to improve bone health is an example of (cause, symptom, treatment, or prevention)? 3. Describe why seeing blood in your urine is a sign of kidney disease/damage?

5/5 Objective Today, we will compare the functions of the basic components of the human immune system and determine the relationship between vaccination and immunity.
Lesson Starter Some diseases are communicable and can be transferred directly or indirectly from host to host. Other diseases are non-communicable. Which disease listed in the table is non-communicable? A) shingles B) impetigo C) hemophilia D) ringworm
Immune System Turn and Talk with your classmates: On Thursday, we talked about the fact that patients do not usually die of HIV/AIDS. They can die of something as small as a common cold. Explain why this is true. HIV/AIDS (virus) attacks the immune system’s white blood cells and the body cannot fight off invaders, like the common cold.
This unit is about maintaining homeostasis in the human body! Homeostasis:
You want to be like this on the inside… Even if the outside world is like this…
One of the main ways to disturb homeostasis is disease! Did you know: Researchers from the Wright Patterson Medical Center in Dayton, Ohio, asked people standing in line at a grocery store checkout and at a high school concession stand to trade a $1 bill from their pocket for a new one. Then the doctors analyzed 68 of those old, worn bills. 87% of these bills contained harmful bacteria that could cause illness! Ewwwww
Essential questions: • What does my body do when a pathogen invades my body? • Why am I not always sick if I come in contact with pathogens often?
Function of the immune system: The army of the body! • Key Point #1: Function- • Fight off infection by keeping pathogens OUTSIDE the body and killing pathogens if they invade the body
Pathogens-review! • 1. • 2. • 3. • Pathogens cause disease! BACTERIA VIRUSES FUNGI
Key Point #1: Fight off infection by keeping pathogens OUTSIDE the body • The skin • Mucous membranes • Stomach acid Key point #2: 1st LINE OF DEFENSE
WAIT!!! What if the pathogen gets past your first line of defense and breaks into your body???
Key Point #1: Fight off infection by keeping pathogens OUTSIDE the body and killing pathogens if they invade the body EVER WELLING EDNESS EAT • Key Point #3: • 2ndsecond line of defense • Inflammatory response • F________ • S____________ • R________ • H________
If the body’s first and second lines of defense don’t work then the immune system must identify and kill the pathogen.
Key point #4: • 3rd line of defense • White blood cells • B Cells • T Cells • “Army”
Pathogen Pathogen Pathogen Key Point #5: Every pathogen has a unique fingerprint called an antigen.
Step 1- Investigate the problem Antibody binding to antigen Step 1: • B-cells bring antibodies that bind to the antigen • Antibodies are flags
Step 2- Call for back-up! Step 2: Antibodies signal white blood cells to fight the pathogen
Step 3- Arrest the criminal! Step 3: T cells break down the pathogens and destroy them
Step 4- Put them in the system • Step 4: Memory b-cells memorizes the pathogen • Antibodies will be immediately released
Vaccines Vaccines DO get your body to produce the antibodies for the pathogen so if you do get sick, you can fight it off easily! Key Point #6: Vaccines contain weakened or dead versions of the pathogens. Your body releases antibodies in case it sees the pathogen again.
Propose an explanation for we see measles steadily decline after 1965. Stop and Jot
For Class Points… C, the SKIN!!! 1. Which of the following is a part of your body’s first line of defense against pathogens? White blood cells Red blood cells Skin Nervous system
B, a disease causing agent! • 2. A pathogen is… A) Pathway for white blood cells to follow to attack diseases B) A disease causing agent such as a virus or bacterial infection C) The best medicine for bacterial infections D) A cell that matches up to an antigen
A, stomach 3. Which of the following is not part of your body’s immune system: Stomach White blood cells Skin antibodies
B, WHITE BLOOD CELLS 4. What part of your immune system can be compared to a SWAT team because it surrounds and destroys pathogens? a) Skin b) White blood cells c) antigens d) antibodies
C, form after a pathogen has been fought off 5. Memory B-cells… a) Help your body remember the part of your body that was last infected b) Show your body how to fight all infections with the help of your brain c) Form after the pathogen has been fought off to help form antibodies in the future d) Remember the type of white blood cell that needs to be used to fight a certain disease
By the end of today you will be able to answer the questions: • Why am I not always sick if I come in contact with bacteria that often? • What does my body do when I do get sick?
Work Time Directions: Using your notes, work with your partner to complete the immune system assignment. When you are finished, begin reviewing for the exit ticket and working on test corrections. Time: 15 minutes Noise: 1 (with partner)
Exit ticket #15 Name: __________ Period: 2 Date: 4/29 Score: _____/4 1. Who is the “army” of the immune system? 2. While you were building a real life model of DNA, you cut your arm. The cut on your arm starts to swell and turns red. What line of defense has been activated? 3. Why will the doctors check your white blood cell count if you are sick? 4. Describe how vaccines work.
