Bloody Hell! Keeping Us Alive, Pt. 4…

Ron Weasley! He’s one of my favorite characters, especially due his tendency of swearing. I tend to swear too. Try to keep it to a minimum… Okay, I’m flying off the handle.

You’re probably wondering what Ron Weasley’s iconic line, “bloody hell!” has got to do with today’s post.

Well, there’s no other way to say it- we’re just gonna be talking about blood. Don’t freak, nothing gross- I promise. I’m not the kind to have a stomach for things like blood and gore, so I’ll try to keep all the disgusting parts to minimum… xD!

Shall we?

The Contents of Blood->

Hmm… I was 9 when I found out that blood actually contained cells too. Needless to say, I was S H O C K E D. It took me a whole day to get back to normal! I still have a vivid memory of choking on my lemonade when my mom told me… xD!

But anyway- what type of cells are present in the blood? There’s actually three main types- white blood cells, red blood cells and platelets. Each of these play an insanely important rule. Aside from that, all these cells float in a golden-y liquid called plasma. Find out more below!

#1: Red Blood Cells->

These cells contain a substance called haemoglobin that gives blood it’s sanguine color. Oxygen molecules bind to the haemoglobin forming oxyhaemoglobin, which is then transported all around the body.

Red blood cells are also called erythrocytes, and they have a biconcave shape. This means that they are very thin around the middle, and begin to become thicker around the edges. There’s a trait very unique to these cells- they have no nucleus! How cool is that? These cells are nucleus-less in order to maximize space for haemoglobin to occupy!

#2: White Blood Cells->

These cells are the spiky looking thingies in the first GIF. Well, they’re responsible for keeping you safe! They fight bacteria, viruses and other such pathogens that find their way into the blood. To be more specific, they engulf the offending microorganism[yes, engulf] in a process known as phagocytosis.

The proper scientific name for this cell is leukocyte. There are many kinds of leukocytes- eosinophils, basophils, monocytes and many more… But we won’t discuss them now. Maybe next time!

#3: Platelets->

Ah, yes. Platelets. These are actually my favorite cell from the blood sector. They have a super important job- to clot wounds!

Platelets are actually bits broken off of other cells. In the very first GIF, you’ll see them as little white pieces rushing along in the plasma. It’s hard to make out, so look carefully!

How do platelets clot wounds? They’re “activated” when a wound occurs- they basically pile themselves upon the wound, clump together and BAM! The wound is clotted. Platelets also weave a net of fibrinogen fibers, which trap other cells and make the clotting process quicker! Cool, no?

#4: Plasma->

Before we begin- I just feel the need to point out that the picture isn’t pee. It looks an awful lot like pee, but it’s not. Sorry, I just had to specify. Moving on… xD!

Plasma is the golden liquid that all the cells float in. It has a myriad of important functions, and composes 55% of the blood. Substances dissolve in the plasma and are then transported around the body to be taken up by the tissues. These substances include- urea, which is a toxic waste product to be filtered out by the kidneys, hormones, which help cell-to-cell communication, and nutrients, such as sugars and proteins.

Plasma also contains a few dissolved gases, and several types of dissolved ions that include phosphates, sulfates and salts.

That’s it! We’re done!

Next post will be the concluding post of the series, so stay tuned!

Thanks for reading! See you soon.

love always,

hi! just a nerdy girl here. lover of science, english and learning on the whole. spreading knowledge is one of my favorite things to do! nothing in life is to be feared, it is only to be understood. now is the time to understand more, so that we may fear less. ~marie curie

  1. Nice write up. In 2016 I had a stem cell transplant. I was in the hospital for a month. The first six days in the hospital involved five intensive chemo treatments that took seven hours each day to complete. The 6th day was only two hours. It was a treatment that was the point of no return, as it killed all my bone marrow. The seventh day was rest. Kind of Biblical. On the eighth day I got the stem cell transplant, and then it was a long wait for the stem cells to kick in and rebuild my immune system. I had zero or no measurable white blood cells for 9 days, and my red blood cells and platelet counts got so low that I had to have two blood transfusions before the stem cells started doing their thing. it was an interesting process. Something I would not recommend unless you really need to do it.

      1. I’ve spent a lot of time without much of an immune system, and I have managed not to get sick. I few months after the treatments for my first cancer, I developed a slight fever. I went to the Cancer Center and I had zero white counts. The nurses freaked, but my doctor at the time was very sensible. I ended up getting seven Neupogen shots (used to force bones to make white blood cells) over seven days and antibiotic drips. My immune system finally kicked back in. The problem was, Neupogen shots cost $5,000 each. So the bill just for those shots was $35,000. Insurance paid form most of it, but I hit my out of pocket on the insurance in a week.
