The human body—God’s masterpiece
The human brain is ‘ … the most complex and orderly arrangement of matter in the universe’. Isaac Asimov
‘I will praise thee; for I am fearfully and wonderfully made: marvellous are thy works; and that my soul knoweth right well’ (Psalm 139:14).
A new twist on blood vessels
Blood vessels are not just straight-through tubes, like water pipes, as was thought. Scientists at Imperial College, London, found that blood vessels have a slight twist to them—they are helical. Colin Caro and Spencer Sherwin showed that the gentle corkscrewing makes the blood flow more evenly compared to straight vessels. They found that, with helical vessels, damage from turbulent flow was much less likely, especially at T-junctions. Smooth flow also encourages the production of health-promoting protective substances.
This could be very important in bypass surgery where veins from a patient’s leg are used to replace sections of clogged arteries around the heart. If surgeons were to give the replacement a slight twist, it could result in a longer time before the vessels clog again.

Our Creator’s attention to detail is extraordinary.
We live in an amazing world. The greatest of all creations is man himself, the marvellous machine—precise and efficient. The human body has a dynamic framework of bone and cartilage called the skeleton. The human skeleton is flexible, with hinges and joints that were made to move. But to cut down harmful frictions, such moving parts must be lubricated.
Man-made machines are lubricated only by outside sources. But the body lubricates itself by manufacturing a jelly-like substance in the right amount at every place it is needed. Yes, the body is a wonder machine, despite the defects from genetic copying errors (mutations) that have accumulated since the Fall of man brought on the Curse (Genesis 3).
The body has a chemical plant far more intricate than any plant that man has ever built. This plant changes the food we eat into living tissue. It causes the growth of flesh, blood, bones and teeth. It even repairs the body when parts are damaged by accident or disease. Power, for work and play, comes from the food we eat.
Even in freezing weather our bodies will sometimes overheat. The body’s own cooling system then takes over. Drops of perspiration pour from millions of tiny sweat glands in the skin. This is a major way in which our cooling system keeps our temperature down. The human body has an automatic thermostat that takes care of both our heating and cooling systems, keeping body temperature at about 37°C (98.6°F).
The brain is the centre of a complex computer system more wonderful than the greatest one ever built by man. The body’s computer system computes and sends throughout the body billions of bits of information, information that controls every action, right down to the flicker of an eyelid. In most computer systems, the information is carried by wires and electronic parts. In the body, nerves are the wires that carry the information back and forth from the central nervous system. And in just one human brain there is probably more wiring, more electrical circuitry, than in all the computer systems of the world put together.1 Yes, it is a wonderful thing—this brain of ours.
In fact, as we look at this very moment, we are actually seeing with our brain. Although, of course, the message is carried there from another marvellous structure, the human eye. Modern cameras operate on the same basic principle as our eyes. In our eye the focus and aperture are adjusted automatically.
The sound we hear is being played on a perfect little musical instrument inside our ear. The sound waves go down the auditory canal and are carried by the bones of the middle ear to the cochlea, which is rolled up like a tiny sea shell. The outer ear operates in air. But the cochlea is filled with liquid, and transferring sound waves from air to liquid is one of the most difficult problems known to science. Three tiny bones called the ossicles are just right to do the job that enables us to hear properly. Interestingly, the size of these little bones does not change from the time we are born.
The heart actually is a muscular pump forcing blood through thousands of miles of blood vessels. Blood carries food and oxygen to every part of the body. The heart pumps an average of six litres (1.5 U.S. gallons) of blood every minute, and in one day pumps enough blood to fill more than forty 200-litre (50-gallon) drums.
Yes, the human body is a wonderful machine. The fact that any one of these devices exists is a complete demonstration that they are the work of an intelligent and skilful designer, God Himself. ‘So God created man in His own image, in the image of God created He him, male and female created He them’ (Genesis 1:27).
The raw material, the basic chemicals in our body, can be found in the ‘dust of the ground’. However, these chemicals cannot arrange themselves into cell tissues, organs and systems. This can only happen with an input of intelligence.
The book of Genesis teaches that God took ‘the dust of the ground’, a heap of chemicals, shaped a man and then blew into his nostrils the breath of life. Then man became a living soul. Human beings are different from animals, for ‘God created man in his own image’ (Genesis 1:27). Our bodies have been designed with the ability to pass on to the next generation the programmed information required to form another person from simple chemicals.
We are more than the chemicals that form our body. We are a special creation of God. Man is God’s masterpiece—His workmanship, the crown of creation.
The best in the universe …
’Without a doubt, the most complex information-processing system in existence is the human body. If we take all human information processes together, i.e. conscious ones (language, information-controlled, deliberate voluntary movements) and unconscious ones (information-controlled functions of the organs, hormone system), this involves the processing of 1024 bits daily. This astronomically high figure is higher by a factor of 1,000,000 [i.e., is a million times greater] than the total human knowledge of 1018 bits stored in all the world’s libraries.’

Mwili wa binadamu <unk> kazi kuu ya Mungu Ubongo wa binadamu ni <unk>... mpangilio tata na utaratibu zaidi wa mambo katika ulimwengu<unk>. "Isaka Asimov: ""Nitakusifu, kwa kuwa nimeumbwa kwa njia ya kutisha na ya ajabu; kazi zako ni za ajabu; na nafsi yangu inajua vema"" (Zaburi 139:14)." Mifereji ya damu si mifereji ya moja kwa moja kama vile mabomba ya maji. Wanasayansi wa Chuo cha Imperial, London, waligundua kwamba mishipa ya damu ina mwelekeo mdogo - ni ya umbo la mviringo. Colin Caro na Spencer Sherwin walionyesha kwamba kugeuza damu kwa upole hufanya mtiririko wa damu uwe sawa zaidi ikilinganishwa na mishipa ya damu iliyo sawa. Walipata kwamba, kwa vyombo helical, uharibifu kutoka mtiririko turbulent ilikuwa chini sana uwezekano, hasa katika T-mkutano. Mtiririko laini pia huchochea utengenezaji wa vitu vinavyolinda afya. Hii inaweza kuwa muhimu sana katika upasuaji wa bypass ambapo mishipa kutoka mguu wa mgonjwa hutumiwa kuchukua nafasi ya sehemu za mishipa iliyofungwa karibu na moyo. Kwa mfano, kama madaktari wa upasuaji wangepiga sehemu ya chini ya mshipa, huenda mishipa hiyo ikawa imefungwa kwa muda mrefu. New Scientist 158 (2134) 19 Mei 1998 Mumba wetu huona mambo madogo-madogo kwa njia ya ajabu. Tunaishi katika ulimwengu wenye kustaajabisha. Uumbaji mkubwa zaidi ni mwanadamu mwenyewe, mashine ya ajabu - sahihi na yenye ufanisi. Mwili wa mwanadamu una mfumo wenye nguvu wa mifupa na tezi zinazoitwa mifupa. Mfupa wa binadamu ni thabiti, wenye viunzi na viungo vilivyotengenezwa ili viweze kusonga. Lakini ili kupunguza msuguano wenye kudhuru, sehemu hizo zinazozunguka lazima ziwe na mafuta. Mashine zilizotengenezwa na wanadamu hutiwa mafuta tu na vyanzo vya nje. Mwili hujipaka mafuta kwa kutengeneza jeli katika kila sehemu inayohitajika. "Hakika mwili ni mashine ya ajabu, licha ya kasoro za makosa ya nakala ya maumbile (muta) ambayo yamejilimbikizia tangu kuanguka kwa mwanadamu kuletwa kwa laana (Mwanzo 3:3).""" Mwili wetu una mfumo wa kemikali ulio tata sana kuliko mfumo wowote ambao mwanadamu amewahi kuunda. Mti huo hubadilisha chakula tunachokula kuwa tishu hai. Husababisha ukuzi wa nyama, damu, mifupa na meno. Hata husafisha mwili wakati sehemu fulani zimeharibiwa na aksidenti au ugonjwa. Nguvu za kufanya kazi na kucheza zinatokana na chakula tunachokula. Hata katika hali ya hewa yenye baridi kali nyakati nyingine miili yetu huwaka moto kupita kiasi. Kisha mfumo wa mwili wa kupoza mwili huchukua mahali pake. Matone ya jasho hutoka katika mamilioni ya tezi ndogo za jasho katika ngozi. Hii ni njia kuu ambayo mfumo wetu wa baridi huhifadhi joto letu chini. Mwili wa binadamu una thermostat ambayo huhifadhi joto la mwili kwa karibu 37 ° C. Ubongo ni kitovu cha mfumo tata wa kompyuta, bora zaidi kuliko mfumo mkubwa zaidi uliowahi kutengenezwa na mwanadamu. Mfumo wa kompyuta wa mwili hupima na kutuma katika mwili wote mabilioni ya vipande vya habari, habari ambazo husimamia kila hatua, hadi kwenye kutikisika kwa kiwiko cha jicho. Katika mifumo mingi ya kompyuta, habari husafirishwa kwa waya na sehemu za kielektroniki. Katika mwili, neva ni nyaya zinazobeba habari kutoka kwa mfumo wa neva wa kati kwenda na kurudi. Katika ubongo mmoja wa binadamu kuna nyaya nyingi zaidi kuliko katika mifumo yote ya kompyuta ya dunia pamoja. Kwa kweli, tunapotazama wakati huu, tunaona kwa ubongo wetu. Ingawa, bila shaka, ujumbe huo hupelekwa huko kutoka kwa muundo mwingine wa ajabu, jicho la kibinadamu. Kamera za kisasa hufanya kazi kwa kanuni ileile ya msingi kama macho yetu. Katika jicho letu mwelekeo na kiwambo hupangwa kiotomatiki. Sauti tunayoisikia inaimbwa na ala ndogo ya muziki iliyo ndani ya sikio letu. Sauti hiyo hupita kwenye mfereji wa kusikia na kusafirishwa na mifupa ya sikio la kati hadi kwenye shingo ya mdomo, ambayo imefungwa kama kamba ndogo ya baharini. Sikio la nje hufanya kazi katika hewa. Lakini cochlea imejaa kioevu, na kuhamisha mawimbi ya sauti kutoka hewa hadi kioevu ni moja ya matatizo magumu zaidi yanayojulikana kwa sayansi. Mifupa mitatu ndogo inayoitwa ossicles ni muhimu sana kwa ajili ya kusikia. Kwa kushangaza, ukubwa wa mifupa hii ndogo haubadiliki tangu tunapozaliwa. Moyo ni pampu ya misuli inayosukuma damu kupitia maelfu ya maili ya mishipa ya damu. Damu hubeba chakula na oksijeni kwa kila sehemu ya mwili. Moyo hupomba damu kwa wastani lita sita kila dakika, na kwa siku moja hupomba damu ya kutosha kujaza zaidi ya matumbawe 40 yenye lita 200 za damu. Ndiyo, mwili wa mwanadamu ni mashine yenye kustaajabisha. Uwepo wa kitu chochote kama hicho ni uthibitisho kamili kwamba ni kazi ya mbuni mwenye akili na ustadi, Mungu Mwenyewe. "Kwa hiyo Mungu akamfanya mwanadamu kwa mfano wake mwenyewe, kwa mfano wa Mungu akamfanya; mwanamume na mwanamke akawaumba"" (Mwanzo 1:27)." Vifaa vya msingi, kemikali za msingi katika mwili wetu, zinaweza kupatikana katika "vumbi la ardhi". Hata hivyo, kemikali hizo haziwezi kujipanga zenyewe kuwa tishu, viungo, na mifumo ya chembe. Hii inaweza kutokea tu kwa pembejeo ya akili. Kitabu cha Mwanzo hufundisha kwamba Mungu alichukua 'vumbi la ardhi,' rundo la kemikali, akamfanyiza mwanadamu na kisha akapuliza pumzi ya uhai ndani ya pua zake. Kisha mwanadamu akawa nafsi hai. Wanadamu ni tofauti na wanyama, kwa sababu 'Mungu aliumba mwanadamu kwa mfano wake mwenyewe' (Mwanzo 1:27). Miili yetu imeundwa kwa uwezo wa kupitisha kwa kizazi kijacho habari iliyopangwa inayohitajika kuunda mtu mwingine kutoka kwa kemikali rahisi. Sisi ni zaidi ya kemikali zinazotengeneza mwili wetu. Sisi ni uumbaji wa pekee wa Mungu. Mwanadamu ni kazi bora ya Mungu - kazi yake, taji la uumbaji. Bora katika ulimwengu... <unk> Bila shaka, mfumo tata zaidi wa usindikaji wa habari uliopo ni mwili wa binadamu. Kama sisi kuchukua mchakato wote wa habari ya binadamu pamoja, yaani Kwa mfano, katika mfumo wa akili (maelezo, habari, mawazo, mawazo) na mfumo wa akili (maelezo, mawazo, mawazo, mawazo) kuna shughuli za 1024 za kila siku. "Hiyo ni mara milioni moja zaidi ya jumla ya maarifa ya binadamu ya 1018 bits kuhifadhiwa katika maktaba zote za dunia.
