INSULIN AND GLUCAGON

October 9, 2019


In this video we are going to talk about insulin
and glucagon and what you need to know about them for nursing school. So before we get started, don’t forget to
hit that subscribe button and click the bell so you don’t miss out on any other nursing
school tips and tricks. Now, let’s do it! Okydoky, so you’re probably heard these terms
somewhere before: insulin and glucagon. You’ll hear them a LOT in nursing school. So insulin is a hormone that’s released by
the pancreas that moves glucose into body cells. And glucose is just a big fancy word for sugar. So when you eat a candy bar, there is a bunch
of sugar in your blood. So insulin goes all around the blood and grabs
onto those sugar molecules, and moves them into the cell. Otherwise, the sugar wouldn’t be able to get
there! Insulin is the key that unlocks the cell,
without insulin, the sugar can’t get into the cell, because insulin is the key. So insulin grabs onto the glucose, and shuffles
it into the body cells, so that the cells can use it for energy. Now, another fancy thing that glucose does
is it tells the liver to store glucose as well. So insulin goes and knocks on liver’s door,
and says, “Hey! Can you please take up some of this glucose,
sir. We need to save it for later, just in case.” So the liver collects some of the extra glucose
in the blood, to save it for later. And it stores this glucose as glycogen. So now we just added another “G” word, glycogen. And all glycogen is, is stored up glucose. So, now insulin’s done it’s job, it was able
to move all of the glucose into the cells, or have the liver store it as glycogen. And now the cells are happy, they have the
glucose they need for energy, and they are going to use it as you go about your day. So now it’s a couple hours after you ate that
candy bar, and you haven’t eaten anything since, and you’re getting a little hungry. Your cells are also running out of glucose,
so they are running out of energy! And here’s where glucagon comes in: glucagon
is another hormone released by the pancreas, and his job is to go tell the liver to release
some of his stored up glycogen. So glucagon goes and knocks on liver’s door,
and says, “Hey liver! The body cells are running out of energy,
they need some more glucose!” And this stimulates the liver to convert it’s
stored up glycogen into glucose for the cells to use. So glucagon’s job is to tell the liver to
break down glycogen into glucose for the cells to use as energy. Now, if this is all making sense to you about
insulin and glucagon, write LOVE in the comments below. Now let’s do some critical thinking around
this: Now that we know the roles of insulin and
glucagon in the body: insulin moves glucose into the cells, it is the key that unlocks
the cells so that the glucose can go inside. And glucagon tells the liver to break down
some of it’s stored up glycogen into glucose for the cells to use, let’s spell out when
insulin and glucagon would be released. We already hinted to it a bit, but we’ll really
spell it out here. When it comes to high blood sugar, which hormone
would you expect to be released? Insulin or glucagon? If you said INSULIN, you are absolutely right! When the blood sugar is high in the body,
meaning there is a lot of sugar floating around waiting to move inside the cells, then insulin
is going to be released to help move that glucose inside of the cells to be used for
energy. Now, on the flip side, when the blood sugar
is LOW, which hormone would you expect to be released? Insulin or glucagon? GLUCAGON! Because glucagon is going to go tell the liver
to convert glycogen into glucose and increase the blood sugar level, because the blood sugar
level is too low. If this critical thinking exercise is helping
you understand insulin and glucagon more, write LOVE in the comments below. I want to hear from you! And that is the role of insulin and glucagon
in the body: insulin’s job is to move glucose into the body cells, and glucagon’s job is
to tell the liver to break down some of it’s stored up glycogen into glucose for the body
cells to use. Now make sure you download the med-surg study
checklist, which will walk you through, step-by-step, how to study med-surg in nursing school. That link is down below for you to snag it. As always, thank you so much for watching,
friend. Now go become the nurse that God created only
YOU to be, and I’ll catch you right back here next time on the nursing school show, take
care.
