Sexual Reproduction Presentation

Create a presentation on vaccine preventable illnesses

Read about these illnesses on BCCDC, CDC USA,  NHS or BC Health Guide for Q 1-5. For Q 6, see resources below.  Create a powerpoint to present to the whole class.  Make sure each member of your group has a chance to present.  60 marks

1. What is the illness? What are the symptoms? Find photos of symptoms.

2. What pathogen is the cause?  How do you get it? 

3. Can the pathogen hide in your body after you get infected? How? 

4. What is the treatment?

5. What vaccine is recommended?  Most vaccines are given preexposure. Can a vaccine be given after exposure, as treatment? 

6.   Read about a recent case, outbreak or recent research. Summarize findings

Fetal Circulation

 

 Click on the picture below to play the video 
 

Today we explored fetal circulation.  First we drew our conception of how fetal circulation might occur. Next we compared fetal and baby circulation in depth in the table below.  Finally we drew a schematic diagram to compare the two and listened to a baby cry because the newborn's first breath is when the ductus arterioles and the foramen ovale closes successfully

   

The Heartbeat, the first sound you ever heard

You have some fill in notes

And their answer key to look at

click on the video below to observe a beating heart

The next video gives a simple and  clear explanation of the chambers, valves and heart sounds

Blood Pressure

 The Major Blood Vessels. DIAGRAM

OK so, during class,  we'll play doctor and find blood pressure.  Have  a look at this tutorial before you test this on each other...

Today you will find blood pressure of the person beside you (participation mark 10)

Lab on Plasma, Lymph, Formed Elements

 Here is some reading on plasma and lymph  link here 

And     NOTES on formed elements 

Here are notes on arteries and veins 

here are some of the slides 

Observe the microscope slides on blood.  For the human samples, 

1.  DRAW THE SPECIMEN. Use a petri dish to draw the circle. 

2.  Label and identify the FORMED ELEMENTS  that you can see such as RBC, WBC, platelets

3.  summarize some information on your specimen using the notes as a guide.  Write these in point form.  Conclusion:  

In a few sentences, identify some of the similarities and differences between human blood and the other mammals such as cat, and rat.  Identify how human blood is different from that of  frog and chicken.   

SPECIMENS:

1.  Artery, vein, nerve of a mammal

2.  Human blood

3. Bird blood or Chicken blood.  Label the RBC and nuclei

4.  Snake blood or  Frog blood

5. .  Human blood: sickle cell anemia 

6.  Rat blood

7.  Cat blood  

8.  Human blood Sickle Cell Anemia 

9.  Human blood: Trypanosoma. (Sleeping sickness)

10 Human blood: Plasmodium vivax (Malaria) 

45-50 All specimens are carefully drawn and labeled. Extensive notes are written beside the observations.  Your work is in colour and brilliantly done

30-44. All specimens are beautifully labeled.   Notes are written beside the observations.

PATH OF BLOOD AS A SUBWAY MAP

 

THE LONDON TUBE MAP

We will use A HUGE map of the circulatory system to represents a subway with stations.  The stations are the lungs, heart, legs, head, intestines, liver, kidneys and all the arteries and veins that connect them.  We will model the passengers entering and leaving this subway today. 

 
REVIEW THE NOTES on the path of blood

Pieces of lego two kinds to be cars on the subway

Hemoglobin car

Plasma car

These are the passengers : 

Oxygen

Carbon dioxide

HCO3 -,  H+

Waste

Nutrients 

Now everyone take a hemoglobin car and start at the lung, oxygen hops on at the lung.  Follow it to the heart aorta and lets go to legs where oxygen gets off and carbon dioxide hops on. 

Put a plasma car on and pick up carbon dioxide too.  Now travel back to heart then lungs, CO2 gets off and oxygen gets on…

Model the rest of the passengers going through the entire system.  Remember that

Oxygen and CO2 can ride on hemoglobin car and everyone but oxygen rides on the plasma car

Here is some reading on Plasma and lymph. another link here 

And     NOTES on formed elements  Have a look and make notes

Assignment 

Create a subway map of the Human Circulatory System which includes
all the major destinations.

1.  indicate arteries and veins as different lines.  Show the direction of the line using arrows. 60 marks
2.  Stations are different areas of the body (Head,  arms, Feet, Liver, Intestine...) and the Heart should be four stations ( left and right ventricle: left and right atrium).  10 marks you mention all stations and none are missing
3.  The map is neat and colourful, inked and it  looks great 60 marks
         55--60 marks - it is easy to read, colourful and inked and extraordinarily creative.
      50 marks - It's impressive!  It's neat, clean and very well done
     45 marks - it is coloured and inked and complete
   0-30 marks- good start, but you probably needed more time
