00:03 Hello, and welcome back to The Creator Revealed.
00:07 We are talking about design in humans. 00:11 And we have someone joining us right now 00:13 who is a doctor and also teaches human anatomy. 00:17 That's right, this is Dr. Lucinda Hill. 00:20 She teaches at Southern Adventist University 00:23 in Tennessee 00:24 which happens to be the school that my daughter went to, 00:26 she's a graduate of it. 00:27 So we are fans of Southern Adventist University. 00:31 Excellent education there. 00:33 And they have an excellent program there 00:39 in origins, 00:41 which Dr. Hill also teaches that course there as well. 00:46 So she is a multi-talented women 00:50 and it's an honor to have her with us. 00:54 Hello, Dr. Hill, it's great to have you here with us. 00:57 Hey, how are you? Good to be with you. 01:00 Thank you. Glad to have you. 01:02 We're doing fabulously. 01:04 Now we've been talking about design in the human body. 01:09 And you're a physician, and you teach human anatomy. 01:14 So I wonder if you can tell us, what would be in your mind, 01:19 a good example. 01:20 I already talked a little bit earlier about the human eye 01:24 and some of the interesting things that are going on there. 01:27 But you work with the entire human body. 01:30 What's something that would jump out at you? 01:34 Something that is really amazing to me 01:37 is the way our bodies are so incredibly 01:41 integrated with our nervous system. 01:43 I have here a model of a human arm, 01:48 hand. 01:49 Think about the incredible things 01:52 that you can do with your hand. 01:54 You reach out, twist to open the door. 01:59 If you're with your spouse, 02:01 you hold hands to communicate love. 02:03 With your children, you use your hands to pick them up. 02:07 We write, we type on computers, and we have muscles, 02:12 a variety of muscles which my students have to memorize. 02:19 And then we have to learn the nerves. 02:21 But think about how in order to make a movement, 02:28 the muscles on one side of the arm contract 02:31 while the muscles on the other side have to relax. 02:35 And the brain controls all of that. 02:38 And so we have centers in our brain 02:40 that receive signals, 02:42 and then give the correct response 02:45 to make these complex movements of these muscles 02:49 to do the incredible activities 02:51 that we do with our hands and arms. 02:54 You know, what I'm looking at that... 02:55 Yeah, you know, when you got all of these parts 02:57 all together, it's pretty amazing. 03:00 But what I was looking at was, 03:02 where the muscles are and what they operate? 03:05 'Cause there are all of those tendons 03:08 and things that go down into the hand for muscles 03:10 that are actually up here in the forearm, 03:13 and so you have a muscle contracting in the forearm 03:16 that's actually moving your fingers, 03:19 for example. 03:23 It really looks like a machine, 03:25 and in a way, you can say it is, 03:27 but it's so much more than 03:28 just sort of a regular normal machine. 03:31 And I'm also thinking about other things 03:34 that are there like, all those tendons, 03:37 they have to be lubricated. 03:39 So you got nerves to tell them 03:41 which muscles to contract and which ones to relax, 03:44 tendons that are moving fingers, 03:47 and stuff way out here, 03:48 and then you got a system of lubrication. 03:53 But you're a doctor, you're a physician. 03:57 And what I'm wondering about is, 04:00 what happens when one of these things is damaged? 04:03 In fact, I can tell you that from harsh personal experience, 04:07 I know what happens when a hand, to some degree, 04:12 when a hand gets damaged. 04:16 Wow. 04:17 You know, 04:19 there are lot of things going on there 04:20 that I simply hadn't thought about very much 04:24 before myself. 04:26 So what happens when you're dealing with a patient 04:30 who is damaged something like that? 04:34 Well, that's an excellent point. 04:35 So many times, somebody will come into the emergency room, 04:38 and I practiced emergency medicine for many years, 04:42 and they have a laceration. 04:45 If it's just a simple cut on the skin, 04:48 even then think of the complexity 04:51 of how do you heal that wound, 04:54 how do you prevent an infection from setting in. 04:58 And then if it's in the hand, like what happened to you, 05:01 let's look at our model again. 05:03 And at here in our fingers, 05:05 we have the insertion points of these tendons. 05:09 If you cut the tendon... 05:11 So that would be the place where the tendon attaches, 05:14 that's what you're calling an insertion point, 05:16 right? 05:18 Yes, that's correct. 05:19 And so to flex your finger, 05:22 you're going to contract the muscle, 05:25 and then that's going to be attached to the bones 05:28 of your finger 05:29 that will then pull 05:32 and bend the finger at the joints, like if the joints, 05:34 what happens if we don't have joints in the fingers, 05:37 if those joints are stiff? 05:40 But back to the lacerated tendon, 05:42 if somebody lacerates a tendon, 05:45 they're going to have a life-changing injury 05:48 unless that tendon is sewn back up, 05:52 and unless we prevent a major infection 05:54 which can also do damage to the tendon. 05:56 And yet our body has an immune system, 05:59 it has mechanisms of healing in various positions. 06:03 We work with those designed mechanisms 06:07 to sew things back up, 06:08 so that they're aligned correctly, 06:10 so that the healing process occurs normally. 06:13 It's absolutely incredible. 06:15 Actually, I can demonstrate that. 06:17 Can you see how I can't straighten this little finger? 06:21 I can't straighten it up 06:22 because the tendon here is broken. 06:25 So I can just get it that far, and that's it. 06:29 I can contract it, but I can't pull it back. 06:32 Even though it would readily go back, 06:34 it'll readily go back. 06:36 But I simply have no control over it 06:38 because the tendon is damaged, 06:41 and I can't do it, yeah. 06:42 You know, the most amazing thing to me is that, 06:47 all of this works together without us 06:50 even thinking of it on a cognizant level. 06:53 It just works. 06:55 You know, what I was thinking about 06:57 when you talk about just a simple laceration, 06:59 your body has to tell cells to start growing there, right? 07:05 Well, how do those cells know to start growing 07:08 and when to stop growing? 07:09 Why doesn't it just turn into cancer or something it is, 07:12 grow into this horrible 07:16 great big growth? 07:20 Excellent point, that is an excellent point. 07:22 We have so many different mechanisms 07:24 that we don't even think of. 07:27 And as you said, it's just automatic. 07:30 If those processes don't work correctly, 07:34 we're in a world of hurt. 07:35 And yet it's incredible 07:37 how well they work most of the time. 07:40 What amazes me 07:42 as much as anything about the human body 07:44 is the way in which it can absorb insults, 07:50 if you will, damage of various cuts. 07:52 Redundancy. 07:53 The redundancy is built in there. 07:56 I guess that it's common to compare biological things 08:02 with machines of some kind. 08:04 So if you said, "Well, a body is something like, 08:07 let's say, a complex machine like an airplane." 08:11 In airplanes, they have redundant system, 08:14 so there can be some damage to an aeroplane, 08:16 and it can keep flying, but with a human... 08:20 And by the way, 08:21 that's indicative of great design 08:25 when you have something like that. 08:26 And let me give you an example of that. 08:27 I've got a wonderful example. 08:29 My grandfather was having some balance issues. 08:32 I took him to a balance center to be tested. 08:35 And once they put the halter on him 08:36 and went through the test, 08:38 when they had him close his eyes, 08:40 he was down. 08:41 So what they told me was, he was relying completely... 08:46 Both of his inner ear... 08:48 He had inner ear problems. 08:49 No balance center in either ear, 08:52 he was relying totally on his vision for balance. 08:56 And to me, that's amazing. 08:59 Yeah, I mean, that's incredible. 09:00 Just that kind of redundancy. All this sort of redundancy. 09:03 And yet he could stand up and walk, 09:06 still just because he had sight, 09:08 even though the rest of the system wasn't working, 09:11 to me, 09:12 what astonishes me is that you can cut entire organs 09:17 out of a human being's body, 09:19 and they don't die immediately. 09:22 I know that, you know, 09:24 we think about things like the appendix. 09:26 But others, I mean... 09:28 Gall bladder, uterus. 09:30 Yeah, yeah. I mean, there's a lot. 09:34 We can live without one of our kidneys, spleen. 09:36 Yes. 09:39 It's amazing. 09:40 And even when we have neurological damage 09:42 in the brain, 09:43 we're learning so much about the plasticity in the brain 09:47 where one part is able to take over function 09:50 for a damaged area, 09:51 and still allow, even though, 09:54 there are certainly bad effects from the original injury, 09:58 yet that's mitigated by these redundancies 10:01 and by the ability to heal. 10:03 It's incredible. 10:04 It really is amazing 10:07 as we think about the human body. 10:10 The more we know about it, 10:13 really the more amazing it becomes. 10:15 And the more amazing we understand it to be, 10:19 the more designed it looks, and the more glory. 10:24 Really is a tribute all to the designer, 10:27 who of course, the Bible reveals to us, 10:29 introduces to us as God, God Himself. 10:34 It's quite incredible. Yeah. 10:37 Well, thank you so much for joining us, Dr. Hill. 10:39 It's been a pleasure. 10:41 Thank you for your insights. 10:43 It's been a pleasure to be with you. 10:45 Thank you. Bye-bye. 10:46 Good bye. 10:49 Well, you know, 10:51 I feel that with this particular subject, 10:56 we've been talking about it for almost half an hour. 11:00 And we haven't even begun 11:03 to scratch the surface. 11:06 Where do you... 11:08 The human body, 11:10 it's not just that it's this machine, 11:13 it's also a work of art, 11:16 it's a beautiful, beautiful thing. 11:18 With the most amazing computer 11:20 that has ever been created right up here. 11:23 Yes. 11:24 And the ability of that computer, 11:26 that brain to control all of these parts 11:29 ultimately though 11:31 the ability to praise the Creator who made us. 11:36 Amen and amen. 11:38 This has been such a special program. 11:39 Thank you so much. 11:41 And you know, it is so true as David said, 11:45 "Lord, You knit me together in the womb, 11:47 I am fearfully and wonderfully made." 11:51 And I just want to take this moment 11:54 to encourage you to praise God. 11:56 There are so many things. 11:57 Sometimes we get ill, 11:59 and we think, "Poor pitiful me." 12:01 But praise God for the ability to regenerate, 12:04 praise God for the way He has created you, 12:08 and praise Him for everything that you can do. 12:11 Thank you. |
