So in this past year I have taken Chemistry, Microbiology and Anatomy and Physiology (science, science, science!). These classes focus more on what's happening on a microscopic level, which is a little harder to grasp. I am a visual learner so when someone's talking to me about something I can't see/touch I have a really hard time. I'm going to do my best to convey this material in a very simple manner. Bare with me. Also, this is not supposed to seem like a science lesson. I just want to show how amazing our bodies are.
First I'll start with the basic structural and functional unit of all living organisms: cells. A human cell contains organelles that allow our bodies to "work". The cell contains the nucleus (which holds all genetic material), mitochondria (energy storehouse), cilia/flagella (movement), and lots of other structures but one more that I'd like to touch on are lysosomes. These structures are absolutely amazing because without them, all of the other organelles would be completely useless. Lysosomes digest foreign bodies, so when things that shouldn't be in the cell are in the cell, shazaam!
There are several systems in the body which all work together, including digestive, nervous, reproductive...etc. We don't realize that our bodies are doing all sorts of crazy things right now. If you have eaten today, our body is breaking every bit of that down (unless you ate lettuce, hah), and separating what needs to be used and what needs to leave the body. Our nervous system allows us to move. You're probably thinking "um no, actually skeletal muscles are what allow us to move.." That's what I thought too, but without the nervous system, we couldn't tell our skeletal muscles to work. The nervous system allows us to receive and perceive information.
My favorite is the endocrine system. Our body secretes so many hormones that regulate homeostasis in the body. We have adrenal glands, which produce hormones regulating stress. We have a pineal gland which secretes melatonin, which allows us to sleep at night. It is automatically, automatically!, secreted when it starts getting dark outside. How crazy is that? We don't even control these things! We also have a pancreas. This is organ is so important for maintaining the blood's sugar level. When we consume too much sugar, the body secretes insulin to bring the glucose levels back to normal, (this is how people are diagnosed with diabetes), and when the body's glucose levels are too low, the pancreas secretes glucagon, which builds on glycagon to produce glucose. Most of us probably didn't even know all of this was going on in our bodies because we aren't the ones controlling it. Let's just think for a second here.. There is so much more going on in our bodies than this, but I don't want to fill you with all kinds of facts. The bottom line is that the way our bodies work is amazing. This is not something that was just coincidence. Think about it: We don't have to tell our heart when to beat, nervous system when to store material, senses when to smell, ears when to hear, eyes when to see, bodies when to produce more white blood cells to fight infections, platelets to coagulate and clog leaks in vessels..etc, etc, etc, etc.
The Lord has taken care of all of these things for us :) I am so, so thankful for that because I am very forgetful and would probably forget to tell my heart to beat 60 times a minute.
So I realize that this blog has nothing to do with microbes. That's okay. I still like the title and I think you understand the overall message I'm trying to convey.. I started this blog originally by telling about the structure of bacteria, protozoa and viruses but I realized that I was sitting in class when I was reading it so I started over.
God is creative, and perfect, and I just think He's so awesome for the way He made us. Everything about our bodies point to a Creator! That's excluding the fact that morality is innate (another blog). This has nothing to do with our thought process or anything that sociologists try to trip us up on. Sidenote: I once had a sociology professor tell me that she let her little boy wear pink dresses because he liked them. um, I'm sorry.. WHAT???
The Lord is good and gracious, and again, so creative! If you think I'm a nerd after this blog, well I am. This stuff fascinates me, and I hope you find it just as fascinating. Have a happy day :)
