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 


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
HCO-,  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

David Hardwick Pathology Museum

 LOCATION: DHPLC PATHOLOGY MUSEUM AT VGH to learn about human pathologies

DATE: April 28 2023 


We will be going to the following location.  Please meet OUTSIDE  the building beside the starbucks
at 845AM for attendance.  Our program will be in rm 2201 and last until about 11am.  Then you will be dismissed to take the bus back to school.

This is a medical facility and there are vulnerable patients who may be immunocompromised. We will wear masks to protect our community members. 

Create a Field Study Safety plan which includes your group members, contact numbers, emergency contact, itinerary and map. Hand this in.

CIRCULATION

 Today we will introduce you to the Circulation System.


This is the slideshow

You will receive a gigantic DIAGRAM on circulation

and we will explore the  path of blood . In particular, we will replicate William Harvey's experiment

Read the Summary notes on circulation:
Circulation System
  Major Blood Vessels
  Lymphatic System

Do the review on blood vessels

RESPIRATION

 




The picture link below shows a journey through the respiratory system



Notes are here and please get the diagram notes from me. Plus detailed notes here
Control of respiration
CO2 and H+ Levels
As monitored by the carotid and aortic bodies.  If these levels increase, they send a message to the  medulla oblongata Carotid bodies send the message through VAGUS NERVE.  Aortic bodies send the message through the GLOSSOPHARYNGEAL NERVE.  Medulla oblongata stimulates the rib cage and the diaphragm to move faster.

Acidosis:  pH < 7.35         too much carbon dioxide
Alkadosis: pHB> 7.45       not enough carbon dioxide (sometimes caused by hyperventilation)

The normal blood pH is tightly regulated between 7.35 and 7.45.

Carbon monoxide:   hemoglobin has a higher affinity for CO than for O2 how would CO affect internal and external respiration?

Presentations

 

Choose one of the following assignments to do, & present to the class:

1.  Read this article and make a poster, powerpoint or cartoon to summarize the main points 

2.  Make a  powerpoint presentation of K2   Find out what foods have these vitamins and what happens during a deficiency.  What cultures have foods that contain vitamin K2. Tell us about how K2 improves bone health.  Include examples such as Natto, or Gouda or another example of food that contains K2

3.  Nixtamalization is a process where maize is soaked in an alkaline solution to help increase the bioavailability of niacin, an essential vitamin for energy reactions.  What cultures practice nixtamalization and what steps were needed to make it happen?

4.  Fecal transplants: This treatment is used for infection of C. difficile.  Describe the symptoms and the risk factors for C. difficile and how a fecal transplant is very effective for treating this disease.

5.  What are some examples of probiotic food and prebiotic food? These foods support a healthy microbiome.  Do some research and present your findings. 

6.  Vitamin D has many functions in your body including for bone health and immunity support.  What are the functions of Vitamin D in the body, what are the food sources and why is everyone deficient in D during the winter months, if you live in Canada? 

7.  Genus vaccinium includes huckleberry, bog cranberry and blueberry.  Investigate indigenous uses of these berries and identify the nutrients that come from these foods

8.  Vitamin A is from marine fish oil, which is a traditional food in populations that live up north.  Investigate the uses of vitamin A in the body and give a presentation on a case study of a population that eats cold water fish or takes fish oil, including codliver oil
