The Immune System-ByTasnim

  1. What is the Immune System?

    The Immune System is a series of special cells and chemicals that helps our body fight off infection and unwanted bacteria. The Immune System contains white blood cells which are made in the bone marrow.

    What are white blood cells? White blood cells make up only one percentage of your blood but they are essential for your health and protection against disease and illness. Imagine you’re at a war and the white blood cells are your soldiers. Because that’s exactly what they are. Loyal soldiers that will fight for you until they’re dead. But don’t worry your bone will keep producing white blood cells so even if some die you’ll always get plenty more.

     

  2. How does the Immune System work? The Immune System works by keeping a record of every virus it has ever defeated so if the virus attacks again the Immune System can get rid of it quickly.

    How does the Immune System keep record of every virus it has ever defeated? The Immune System is a superior memory bank which is why you only get the measles or chicken pox once.

     

  3. How does the Immune System help us?

The body’s defence:

  • Our skin is a waterproof barrier that makes oil that can kill some bacteria.

  • Your lungs are designed to trap mucus and push it out of your body (coughing it out).

  • Your stomach is filled with acid that can be used to kill most viruses.

  • Skin oil, saliva and tears contain anti-bacterial enzymes that reduces the risk of infection.

  1. What can we do to make our Immune System stronger?

  • Don’t smoke

  • Have a healthy and balanced diet

  • Exercise every day for the same amount of time.

  • Keep a healthy weight (weighing too little is just as bad and sometimes worse than weighing too much).

  • Control your blood pressure

  • Avoid alcohol

  • Get enough sleep

  • Wash your hands frequently

  • Cook meat thoroughly

 

Some interesting facts:

  • The common cold can be caused by many different viruses so it has to be fought many times.

  • Fever is actually caused by the Immune System. A rise in temperature can kill some viruses. It can also trigger the body’s repair process.

  1. But the Immune System is not infallible:

  • Allergies are just the Immune System feeling threatened by harmless substances.

  • Autoimmunity is the Immune System attacking the body’s own structure when it fails to recognise the structure (eg Lupus erythematosus).

  • Rheumatoid arthritis is the Immune System attacking the joints (causing inflammation and swelling).

Tasnim, so glad to see a post on this topic.
This is very useful and informative. It is really helpful to understand how our immune system works.
Great post
Please add pictures and diagrams with food/fruit that can strengthen the immune system.

Tasnim, I found your blog really entertaining as well as informative. Great analogies. Am wondering if you could format it better to make it more easily read on screen? e.g blocks of text, text less spread out, illustrations (attributed of course). I look forward to reading more of your blogs. A great inaugural student blog!

Thank you Tasmin for this lovely informative blog post on the Immune system.
Recently scientist as finding that the immune system can be 'overridden' by various types of diseases. Have you consider how the Immune system can be hindered or 'wiped clean of its memories of these viruses'?

A well written and very informative blog on the immune system Tasnim. My little soldiers have been very busy of late battling the cold I have. They are winning ;) Cant wait to read your next post.

Dear Tasnim
A great topic and very timely since the cooler months ('germs') have arrived. I like the dot points and the sub headings which summarise the topic and make it easy to skim and read.
Thank you
Mrs Stefanidis

Dear Tasnim,
Like Mr Krupa, my "soldiers" have also been very busy! It was great to read your blog and think about how hard my immune system is working to keep me healthy. Thank you for including the section, "What can we do to make our Immune System stronger?". It was a good idea to have a list of things that we can do to support our "soldiers".
:)

Great work being the first person to write a blog post. It's very brave.
The immune system is a great topic because it affects everyone. People like to read about it because its relevant to them and people are generally interested in themselves. Because of this, your posts would be more engaging if you started by telling people why the topic is relevant to them.
e.g. "everyday your body is bombarded with infectious pathogens, the air your breathe is filled with fungi spores and the device you are typing on is laced with bacteria. How do you survive this onslaught? your immune system"

For more info on the immune system, I suggest watching this video. It's my favourite animation on the immune system.
