Respiratory System




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?

What's on the test?

ON THE DAY OF THE TEST, HAND IN:
You must make a BIG ILLUSTRATED SUMMARY OF THE TOPICS WE COVERED.  THIS WILL BE OUT OF 10 MARKS.  IT MUST BE IN INK, IN COLOUR, AND INCLUDE ALL MAJOR VOCAB.

There will be a multiple choice test this friday May 3  based on the following.  Note that Fetal circulation will be excluded since it was not mentioned in class.

1.  your heart dissection.
2.  These notes which I gave out.
 the slideshowCirculation System
path of blood notes
  Major Blood Vessels
Do the review on blood vessels .
 and work on this guided study based on these summary notes
3.  Your notes on ECG:  these  fill in notes

review your gigantic DIAGRAM on circulation

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

Blood pressure

The Major Blood Vessels

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...

CIRCULATION INTRO, PATH OF BLOOD

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

Genetic Diseases Presentations

Choose a topic on Genetic Diseases.  You have one period only to come up with a group presentation.
Find your topic on this website

https://www.genome.gov/10001204/specific-genetic-disorders/

Log into Microsoft Outlook.
Create a powerpoint on Microsoft Outlook and share the powerpoint with scng@vsb.bc.ca
Work with 2 other people in the class.
Each person will make their own slides in the presentation

Presentation Rubrik 50 mark

10 marks:  
How does it look?
You have presentation slides and they are well designed, with minimal text and relevant pictures
7-10 marks - it is well designed
4-5 marks - it is crowded with words but it has good pictures
0-4 marks -   it has no pictures

20 marks: 
Content: remember your content will be delivered mainly as SPOKEN WORD and PICTURES. your script should be long, with as many words you need to tell the story but the words on your slides ought to be few. 
Your presentation presents the material in a way that is
18-20 marks - comprehensive.  You  explain the main points and your content is thought provoking and interesting.
14-17-   covering the most important and relevant points. You do a good job.
10-13 -  showing main points.
0-10 - a pretty good start

20 marks:
Spoken presentation
18-20 marks:  you make eye contact with the class and spend more time looking at us than your notes.  you speak loud and clear. You have a creative way to keep us engaged.  For example, you use props.
14-17 - you do a pretty good job making eye contact with the class.  you speak loud and clear.
10-13 -  you speak loud and clear and you are mainly reading out loud from your notes.  You make some eye contact but you look at your notes more than looking at the class.
0-10 - you only look at your notes and speak audibly but it is difficult to hear what you are saying.

Blood Types

Today we will review a case of multiple alleles and blood types and you will practice the questions from this website here

Friday 1 February 2019

Vulcan Mating Ritual

Mating Lab: 
Purpose:  To have hypothetical offspring with at least 4 other individuals
In the class and calculate the probability of certain traits using a punnet
Square.  Next, you will perform a Vulcan mating ritual (pon farr) where
you randomly pick an allele from the other person and they randomly pick
one of your alleles.  Then observe the traits of your offspring.  Have 4 kids per mate
Keep track of the genotype of each kid.  By the end of the activity, you will have 16 kids


Method:

Write down your phenotype for the following characteristics:

Earlobe attachment or unattached   E e
Tongue rolling or not                       T  t
Cleft chin or smooth chin.                 c
Widow’s peak or not                          w
Natural curl or straight hair         n
Dimples or not       D d
Righty or Lefty       R r
Freckles or not       F f
Girl XX or boy XY

For each trait, make the genotype as alleles on two small pieces of paper.
 Write your phenotypes now:


For each mate you have draw nine punnet squares  representing
 each trait and
calculate the Probability of each trait.

Mate 1’s  genotype:_Ff WW tt nn rr dd cc  Ee__XX_________________
Punnet squares: indicate probability


choose two characteristics to demonstrate a dihybrid cross


Actual genotypes of the offspring. Draw a cartoon of your kids. Name them
Offspring :
