How to take blood pressure

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

You will get notes on ECG and the conduction system of the heart

The conduction system of the heart:






 You will also get a cartoon to label and a worksheet today so you can see the relationship between conduction system and the way the heart fills and ejects blood.  Finally, you'll see where the heart sounds come into this whole picture.

A Heart Beat, the first sound you ever heard. These videos are complex and make sense the more you watch them

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

The flow of blood and types of blood vessels

We will review the Circulatory System and you will map out what happens at each section of the Systemic and Pulmonary Circuit.

 We will map out the path of oxygen, carbon dioxide, nutrients and waste and familiarize ourselves with the names of major arteries and veins.
Here's a great crash course summary which talks about the vessels and the direction of blood flow:

Be familiar with the   Major Blood Vessels





Some details on the Hepatic portal system here:

We will start the Circulation Unit.

Just finished a RNA test.  You'll get the results back next block.

Our new unit is circulation.
We will be going through these resources for class notes and I will provide diagram notes on the following topics: Please bring a paper or digital copy of these resources to class:

Raycroft summary notes:
Circulation System Intro 
   (note that I'll have a correction for this resource in the heart sound section)
Blood
  Major Blood Vessels
  Lymphatic System

Classwork:
1.  lecture and notes on An Overview of Circulation
2.  lecture  and notes on Path of various substances in the blood in detail.
We will map this out in class.
3.  Demonstration of Artery flow (pulse)  and classroom demo of venous flow with valves (we need someone in the class to pop their veins for us...

Homework:  
1.  Work through  some useful diagram resources:  these sample exercises here to review the path of substances in the pulmonary circuit.
2.  Know how to label the diagrams
3.  Watch the crash course below

Genetics Quiz Friday

Your Genetics Quiz will test your ability to solve for the following. Be prepared to draw a punnet square for

Complete dominance
Co-dominance
Sex linked alleles

I will expect you to draw a pedigree, practice from this website, which is an educational resource for health professionals who provide sensitive genetic counselling.
You will answer a question on medical ethics for which I will accept any ethical answer where I can follow your reasoning.

Practice problems

 worksheet for Monohybrid crosses : http://www.biologycorner.com/worksheets/genetics_practice.html

And here is its answer key: http://www.biologycorner.com/worksheets/genetics_practice_key.html

 sex linkage questions here: http://www.k-state.edu/biology/pob/genetics/intro.htm

More Genetics problems, this time focussing on Bioethics - taking a family history and the role of a health professional in disclosure

We will do some more practice of Genetics and go over some questions. Today we will also learn about pedigrees.  In fact, I'll dictate a pedigree for our test.

Angelina Jolie wrote about  a very public double mastectomy , raising awareness of the risks associated with the BRCA 1 and BRCA 2 gene.

 I will give you a patient scenario and you will draw a family history.  an example is below:  BRCA 1 and BRCA 2 are autosomal alleles which are strongly linked to cancer, particularly Breast cancer.  (see this fact sheet).  Genetic counsellors interview patients to assess their risk by drawing a pedigree.  You can practice drawing a pedigree here.  As you watch this video, and read the links, make conclusions about the type of allele which may lead to the breast cancer phenotype.

This illustration is from a worksheet created by the National Genetics and Genomics Education Centre

Genetic Counsellors use detective work to sensitively discern a patient's risk for a genetic disease.  There are bioethical guidelines which govern disclosure.  And there's no easy answers for communication.  Have a look at this scenario to see some of the ethical concerns, and imagine that you are a health professional in this situation:

Test on Protein Synthesis and Genetics

1.  Steps for Transcription of DNA to RNA, including the processing of the mRNA
2.  Steps for Translation of the mRNA, including INITIATION, ELONGATION AND TERMINATION. Look at the raycroft notes And cartoon notes.
3.  Know the answers of the DNA worksheet given out.  Emphasis on transcription and translation. Key here 
4.  optional questions :Know how to solve Genetics Questions  including drawing a pedigree
5.  optional questions :Read about the kinds of mutation and be prepared to write about two of them.
6.  optional question:What are the three forms of protein:  primary structure, secondary structure, tertiary structure.

Test date is Feb 11, 2016
