Friends of mine may wonder why I study what I do. But those who know me best know I study the body because I love it; I am constantly telling the poor things about boring topics that I find fascinating. Yes, I don't go out as much as the average spring/summer student and get less sleep than I'd like, but it is worth it. I love this study. I love learning about the genius organization, the artistic design, the miraculous intricacies of our bodies. I hated chemistry in high school, but after learning how it is the most integral part of the body, how every process, every movement, every sensation, and every regulation is an effect of chemical processes, I find my chemistry class fascinating.
Think about it. Your body converts the bread you eat to fuel your fingers typing. It uses sodium and potassium ions moving via a gradient of high to lower concentration to send signals from your brain to the voluntary and involuntary parts of your body--telling glands to secrete essential hormones and telling your tongue to move when you want to speak. Pressure receptors in the skin work so that they sense the immediate touch of something, but cancel out the reception thereafter, so you aren't irritated with the feeling of ever-present clothing, rings, glasses, etc. Your heart forms during development in a twisting formation so that when it beats, it contracts with a wringing affect, efficiently pumping the most blood for the amount of energy invested. Your lungs are at the right pressure so that as the lung cavity expands, air naturally floods the lungs as it goes from a higher atmospheric pressure to the lesser pressure inside the body. The biggest, most important nerves, veins, and arteries are deep, in between muscles, so as not to be affected by minor injuries. You encounter millions upon millions of microbacteria a day and your immune system functions at peak performance with many specialized cells so you get symptoms of an illness say 1-5 times a year. Your muscles are so incredible; with one or two steps up stairs, you can stop thinking about the steps and your muscles retain the memory of the height and energy required for each step; you need no longer think about it. You have a reflex arc, where, upon touching a hot surface, the signal needs only go to the spinal cord for optimum speed of a reflex to contract the appropriate muscle. Your brain and muscles can control the strength and magnitude of every movement; you can pick up a pencil or bench press 100 lbs. The hand can perform a gross movement such as itching your leg or the finest movements of a dentist, sculptor, or surgeon. The brain is a powerhouse that houses our thoughts; controls our internal temperature, sleep cycle, emotions, and interpretations; can communicate with the Holy Ghost; and can invent vaccines, artistic expression, the airplane, and theories of physics, sociology, and chemistry. The body regulates a complicated array of hormones that cancel each other out, signal the release of other hormones, and even regulate the development of an embryo. A woman's body can create life and sustain it. This is the greatest miracle of all.
I could go on and on, but wanted to share with you some of the words of the brethren.
