The Wonders of Coagulation

"I praise you because I am fearfully and wonderfully made..." ~Psalm 139:14

Yes, in case you could not tell from the title, I am a nursing student. I'm not going to shy away from it. God has shown me some of the wonders of the human body through Anatomy and Physiology, and all I can say is that He truly is amazing for having created us.

So I am offering a slight warning. I'm going to talk about the amazing-ness of blood clotting. I will not post any pictures (mainly because I hate using pictures from the internet and I don't particularly feel like bleeding for a camera), so those with squeamish stomachs are safe. I will, however, talk in-depth about blood clotting and do my utmost best to point out the beauty in this single body system. And it's not even a single body system. It's a very small portion of the circulatory system, but every part of blood clotting is so intricate and amazing.

So it starts with an injury. I bashed my knee when I slipped on Saturday at work. I broke a couple small blood vessels (the bruise on my knee is evidence enough) near my patella (knee). Immediately, to prevent major blood loss into the tissue around my knee, the blood vessels constricted. Little fragments of cells called platelets noticed that there was a gap in the blood vessel when they could see the collagen that is right outside the vessel walls, and they started sticking to the collagen and to each other. They quickly formed a platelet plug. While they are sticking, they do something called degranulate - which basically means they release their contents, including factors that call white blood cells and platelets (to keep up the sticking cycle) to the site, as well as triggering coagulation and more constriction of the blood vessel.

Thus begins coagulation. There is an extrinsic mechanism and an intrinsic mechanism that MUST happen in order for a clot to form. Both include a cascade. One factor activates another factor which activates another factor, which activates two more factors, which one activates another factor, and the other goes back in the cycle and keeps activating other factors. I think I just confused myself with that sentence. But you get the picture. If ONE of these factors does not work properly, the entire cascade is thrown off. That's how intricate this system is. Isn't it cool? Scientists call it "irreducible complexity" which is fancy language for saying that this system is so complex that it cannot have steps taken out without disrupting the whole system. Bleeding disorders like hemophilia or von Willebrand disease occur when one of the factors isn't working properly or there isn't enough to trigger the rest of the reaction.

I guess you could look at it as a chain reaction where one of the chains explodes in a different direction. Or with dominoes, if you set them up in a line where one will tip down one and then another, and so on and so forth, and one of the dominoes is set a little farther than the others, either the tipping will stop sooner than you wanted, or it will stop altogether. This is where I wish I had a set of dominoes and a camera...

It's so cool! The human body is made in a beautiful way so that each system works. The heart itself has backup mechanisms that will kick in if something doesn't work right. We don't bleed to death. What's more, our body automatically fixes stuff. When I stub my toe (or bruise my thigh...) I don't have to tell my platelets and clotting factors, "Hey, guys I could use a little help here..." I don't have to tell my heart to beat at the intensity it does. I don't have to tell my body to do a lot of the things it does. It's really quite amazing. Anyone who cannot see the wonder and beauty in the body is a fool, indeed.

Our God certainly is creative. *love*

Creation and Choreography

Here at Messiah, Spring semester of their first year, students are required to take a class called "Created and Called for Community," also known as CCC (or triple C or C-cubed... whatever floats your boat). The class is split up into three sections, of which I only remember the first - Creation. Mainly because everyone in CCC has to do a Creation Project. What is the Creation Project? You ask. I'll tell you.

Maybe someday.

Not in this paragraph either.





Nor in this one.








I think I've tortured you enough.







ENOUGH!

The creation project seeks to make students dig deep within to find the creativity that God gave them to do SOMETHING related to creation. That means one can write a poem or short story or short essay, or paint or draw a picture, design a computer graphic, put together a video, a song, a dance... yes, the options are limitless. It just has to do with creation.

But in this, I am stuck.

I knew right off the bat that I wanted to choreograph a dance. I LOVE dance, so it would make sense for me to use that art form.

The trouble came in choosing a song. Should I choose a worship song? Can I find a song on creation and dance to that? Ooh, I could find a Hebrew song about creation! Oh, most of them are about love...

See my dilemma? So right now I'm torn between using choreography I came up with to a song by Gad Elbaz, an Israeli artist, or choreography for a worship song. Or even ditching the choreography I already have been working on for both of those songs for another time, and choosing a new song altogether. Aaaarrrghhhh.

And so, my dear readers (all two or three of you), what should I do? This is the description for the project:

Students will interact with the assigned texts by producing a project that demonstrates their understanding of one of the themes within the creation unit, such as the creation of the earth, the role of arts and culture, humanity as created being, or the significance of creativity. The project’s form should reflect your interests and skills...

These are the songs I have considered or already have choreography in progress for. I'll include the other part-choreography ones just to see what you think.

• Mashmauyot by Gad Elbaz
• Here in Your Presence by New Life Worship
• Beloved by Tenth Avenue North
• We Delight by Caedmon's Call (Those who know I already completed the choreography for this years ago, I am in the process of revamping it.)
• Find your Wings by Mark Harris

And songs I've already choreographed that I could record a performance of:

• Blessed Be Your Name by Tree63
• Born Again by Newsboys
• Sing Your Praise to the Lord by Amy Grant

So, what do you guys think?

The next step of the joyful adventure

It has now been three days since I arrived on the grounds of Messiah College as a brand-new first year student. I was so happy to be here when I arrived, and I'm still pretty happy. My roommates are great, the campus is beautiful, the food is good. The schedule has, however, been crammed with necessary but annoying orientation sessions on all kinds of things. The things I'm most fuzzy on have not been covered in the sessions or schedule. Oye vey.

Classes don't start until Tuesday, and I'm both glad and anxious for them to come. Glad because some of my textbooks have not arrived yet... but overall, I'm excited for them to start. I'm taking some really cool classes (courtesy of being in the nursing program and the honors program), like the writing class on the amish, anatomy and physiology, and foundations of marriage and family. I'm so excited about anatomy and physiology, and also for chemistry. I am such a scientist because I LOVE to learn about God's creation and explore it. I love all the labs in chemistry, and I love learning about the body. Each system is so complex, so that when you put them all together, they completely blow your mind. How can anyone say that we came from a mass of exploding gases?

On another note, my dorm building's theme is "Choose Joy." This seems to be a recurring theme in my life. In middle school, back when I was that awkward little kid with the weird obsessions and such, my mom told me that I needed to choose joy in life, because if I looked at all the pain and sorrow and strife, life wouldn't be so hard. The first week at the Springs, Pastor St Cyr spoke about joy - real joy. So often people use "happy" and "joyful" synonymously, when they really aren't. Happiness is based on circumstance - "I'm happy to see you" or "You make me so happy" or even, as my friend's dad puts it, something can have "happy-making qualities." Joy, however, is rooted in contentment and in God. It is deeper than happiness. It is more than happiness. It is something that burrows deep into your soul and thrives in contentment.

Joy is beautiful. Happiness is fleeting, joy is eternal. It is only when we take our Lord as our companion that He shows us the priceless value in joyfulness.

So, it is fitting for my first-year theme to be "Choose Joy." It hasn't just been a first-year theme; it is a life theme. The picture here is a graphic my friend Aaron designed. His website is www.worksofhishands.com if you want to look at the other artwork he's designed. In any case, the scripture he's chosen for joy fits perfectly. Our souls are joyful because the LORD, the Lord Almighty, has compassion on his children. We are redeemed because he loves us so, and we rejoice because of that. Because of that, we find so much more joy in knowing God.

Shalom, and may you find simcha (joy) this week!
