    00:01 So, Killer Factor 2 of 4.

    00:03 We're talking about your pancreas.

    00:04 Balancing blood glucose.

    00:07 I love this picture that I have here for you.

    00:10 You got the pancreas up there.

    00:11 There is kind of the fulcrum on the balance, because we're looking at the pancreas thats helping us create hormones that control blood sugar.

    00:19 See an imbalance of these hormones will cause the blood glucose to not be controlled.

    00:24 So killer factor 2 of 4 is balancing your blood glucose.

    00:29 So if I don't have enough insulin, if I have too much glucagon, I'm gonna have a real problem.

    00:36 Now beta cells make the insulin in the pancreas and alpha cells make the glucagon.

    00:43 So beta cells make the insulin, alpha cells make the glucagon.

    00:49 I want you to go ahead and fill that in now.

    00:51 So which cells make the insulin? Good beta.

    00:56 Which cells make the glucagon? Alpha.

    01:00 What are these both? Hormones.

    01:03 Good job.

    01:04 So you've got those words in there.

    01:05 We've used those words multiple times to help that really stick in your brain.

    01:10 I know the second of four killer factors is that balancing of blood glucose, if it's not done, well, you're increasing your risk for developing type 2 diabetes.

    01:21 If you don't have enough insulin, you have too much glucagon, this is going to be problematic.

    01:25 So in type 2, beta cells aren't able to make as much insulin.

    01:30 They might just be playing tuckered out.

    01:32 They might just be worn out.

    01:35 So I want you to write a little downwards arrow, about insulin, that's the end result.

    01:40 But while you're there, also put the upwards arrow because remember, in type 2 diabetes, you can also have a lot of extra insulin in the beginning stages of the disease.

    01:51 You're just resistant to it.

    01:53 So you should have two arrows by insulin.

    01:56 Downward arrow for less insulin is the end result.

    02:00 But an upward arrow for initially you have this bull that body's trying to get that glucose into your cell.

    02:06 So you have a lot of extra insulin.

    02:09 The body just can't use it.

    02:12 Now, chronic hyperglycemia eventually is going to take its toll.

    02:16 That's why you have the insulin resistance.

    02:18 Another problematic in keeping a controlled blood sugar.

    02:22 So let's go back to our graphic.

    02:24 Let's review to make sure that you have this content clear.

    02:28 Which of these is produced by beta cells? Go ahead and write that in.

    02:34 Which is produced by alpha cells? Well, that kind of narrows it down when there's only two choices, right? Hey, take the win when you get it.

    02:43 Everybody needs that in nursing school.

    02:45 So which of these hormones will cause cells to take up glucose from the blood? Which will cause blood glucose to rise? Okay, so I hope you answered that.

    02:56 Glucose is the hormone that causes you to take glucose from the blood and into the cells.

    03:03 Glucagon is the hormone that's going to cause blood glucose to rise.

    03:07 Now make sure you have that down in your notes.

    03:09 It's really important as we talk about treating and helping diabetic clients.
