June 23rd Bioscience 1

Hi All, I hope your study for the test on Friday is going OK. Know that if you are having trouble understanding something or just have a question you want clearing up as you study, I am here at the end of the email.

Over the weekend I posted the answers for the cardiovascular and lymphatic systems workbooks, so check these out on BlackBoard when you have worked through the workbooks.

I have also put up the second online question on Google groups. I know there are a very few people who need to participate in the online discussion so make sure you think about the questions and post your response. Of course you are also welcome to have your say if you have participated in the first discussion. The more points of view the merrier. David is putting all the points made into one grand document.

The lymphatic quiz will be up till Sunday night 29th June, so dont forget to get your 2 marks from that --it is good as a revision exercise.

Best wishes, Ruth

June 17th Bioscience 1

Hi Everyone, By now you should have finished Unit 5 on the cardiovascular system and be on top of Unit 6 on the lymphatics so that your way is clear to revising for the final test. This is on Friday June 27th at 1-3pm, probably on the 6th floor.

I have now written the test and David has moderated it so I can give you some details about what it will entail.

You will have 2 hours to answer questions in 10 sections. Each section will be worth 10 marks. The sections are: 1. Chemicals; 2. Cells and cell processes; 3. Tissues; 4. The integument; 5. The skeleton; 6. The muscular system; 7. The heart and circulation; 8. The blood; 9. The lymphatic system; 10. 2 longer questions each worth 5 marks chosen from a list of 8 possible topics.

Questions 1-9 will be similar in style to the questions you have already met in the first two tests.

The last question will give you a chance to give more in depth answers than are expected in the other 9 questions. To give you an idea of the sort of topics, they could be such things as: Bone growth; White blood cells; The skin and temperature control; Aerobic and anaerobic respiration and muscle contraction; Movement of substances through the plasma membrane; etc. (Note: these are examples only - these will/may not be the questions given!!!!!!).

Each of these longer questions is worth 5 marks, so we generally think of allocating 1/2 mark per point made. So to get 5 marks you need to think about providing at least 10 correct facts. These could include drawing a diagram and labeling it correctly for 1/2 mark per label + ? marks for the diagram itself depending on its complexity, describing a structure or process correctly and giving its function, etc.

This test is worth 50% of your final marks and the resit policy will be slightly different--not that any of you will need a resit!

You still need to gain a mark of 75% or over to show competance and you need to get above 40% to be entitled to a resit.

All resits will involve a written test for which you will either need to come into the polytech at designated times or organise an approved supervisor for. For marks of between 40% and 60% you will need to sit a complete resit on a new test. Above 60% and you can revisit the questions that you missed in the first test, but written under closed book, supervised conditions.

I hope this gives you a better idea of what to expect. Perhaps email me on the group email if you have more questions about the format that I haven't answered here.

Best wishes, Ruth

Monday June 9th Bioscience 1

Hi, Just when I thought I was on top of getting the last topic up on Blackboard for you, it all went to custard! Anyway I found reading the instructions always helps and now I have the interactive version up and running, the workbook is there and I have corrected the fault in the quiz! So I now have fingers crossed that it all works as it should.

So today you should be thinking about getting the cardiovascular quiz completed, as it will go off line in 6 days time, and getting into the last Unit on the lymphatic system. It is probably the shortest unit so should be no problem for you!

You should have heard from me now about your test results. Most people did really well. Congratulations!

June 2nd Bioscience 1

Hi, I hope you all enjoyed the heart dissection yesterday and, if enjoyed isn't quite the right word, I hope it was useful and interesting!

The timetable suggests finishing off the circulatory system this week and then moving on to the last topic, the lymphatic system next week. I shall post this last unit at the end of the this week.

In response to our discussion at the block course, I have been looking up information on the foramen ovale which is the opening in the foetal heart between the right and left atrium that allows the blood to bypass the lungs. The best description I could find was on Wikipedia at this site http://en.wikipedia.org/wiki/Fetus . Scroll down to the section on Circulation where the foetal heart is described and then under Postnatal development it describes how the opening closes as soon as the new born takes its first breathe.

For those that were asking for more worksheets, there are three useful ones on the heart, blood and circulation on the Wikieducator Anatomy and Physiology of Animals site http://www.wikieducator.org/The_Anatomy_and_Physiology_of_Animals

Just remember that in animals the human superior and inferior vena cavae are the cranial and caudal vena cavae. Also the heart valves in animals tend to be called atrio-ventricular valves rather than bi-and tricuspid valves.

All the best, Ruth
