Ask Mr. Hobbins the answer to that one!

Next up is the Endocrine System, which consists of glands that produce hormones that travel in the bloodstream to various sites of action.  We’ll look at this from the perspective of coordination and control, so will be defining the term homeostasisand looking at examples of this in the body.

Questions we’ll tackle:

  • What is the endocrine system and how does it function?
  • What is homeostasis and how does it work?
  • How is body temperature is regulated?
  • How are blood glucose levels maintained?
  • What’s the difference between type I and type II diabetes?

Another great presentation from Mr Taylor.

Playing doctors

Monday, January 25th, 2010

We are going to do a little role-playing.  Here are two scenarios:

You are a new mother of a 2 week old baby.  Throughout your pregnancy you read a lot about breastfeeding vs bottle-feeding.  At your first doctor’s appointment since giving birth, the doctor asks you which method you have chosen, and why, and how it is going.  Script the conversation between you and the doctor.  Do some research to find out the composition of breast and bottle milk, and discuss the benefits and drawbacks of your chosen method.  Include ethical and social issues as well as medical ones.

You are a doctor who has recently confirmed a diagnosis of type II diabetes for a particular patient.  Script a conversation between you and your patient that includes what the causes and symptoms are, the relevance of ethnicity, what the dangers are, and any dietary advice (with justification).

The kidney

OK – this is the last section of the syllabus before we begin our options.  Here are some of the key points we’ll learn:

  • What is excretion? (And what isn’t)
  • How to draw and label a diagram of the kidney.  We’ll dissect one too.
  • What a nephron is, how to annotate a diagram of one to help explain the processes of ultrafiltration and reabsorption.
  • What is osmoregulation, and what role do hormones play in it?
  • What are the differences between concentrations of various components in blood and urine, and the reasons for those differences.

We’ll again use this wonderful presentation from Mr S Taylor as well as our textbooks.  In addition, once we’ve completed this topic, you could watch this video.  It’s a little complicated, so I wouldn’t recommend watching it at the start, but after we’ve covered some of the theory.

Another useful review powerpoint from Mr Hobbins: 11.3 The Kidney

Enjoy!
