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.
