BIOLOGY: ENDOCRINE SYSTEM

Added: 2026-05-09

[00:00:00]Welcome to this platform. So, today's biology lesson we are going to answer a question coming from the topic endocrine system. Now, let us define endocrine system before we look at the question.

[00:00:09]So, when you talk of endocrine system, what does it mean? So, endocrine system simply refers to the system of coordination that is made up of what?

[00:00:16]Ductless gland. And this ductless gland produces hormones. So, another term that you should define or another term to define is a hormone. So, what is a hormone? So, let us interact in the comment section. Make sure that you put your answer there. What is a hormone?

[00:00:30]Okay, so let us look at the question.

[00:00:33]So, the question reads, "Figure 2.1 and 2.2 show two glands, P and Q, respectively." So, as you can see, gland P and also we have gland what? Gland Q. So, this is gland P and that is Q. So, when you are given such a question, the first question surely is identify.

[00:00:55]So, let us look at it. Identify the endocrine gland P and Q. So, they want us to identify gland P and Q. So, what are these gland? So, this is a kidney and the gland that is found on top of the kidney is actually known as what?

[00:01:13]Adrenal adrenal gland.

[00:01:16]Adrenal gland. So, this is known as adrenal gland. Then what about Q? Q, as you can see, this is the idiom.

[00:01:26]So, this is the pancreas. So, that is the what? The pancreas.

[00:01:30]Okay, it's the pancreas.

[00:01:33]Then coming to the second question, and let me just say, when you look at the topic endocrine system, these are not only glands that we discuss. So, as you prepare this part, make sure that you know all the glands. Starting with the pituitary, talk of the thyroid gland, talk of the ovaries, the testes, and all those you need to make sure that you know them and where they are found and the functions. Okay?

[00:01:57]Let us look at the second question.

[00:01:59]State one hormone produced by each gland. So, these glands that we've named, what is that one hormone produced? Just one. It might be more than two. I mean, it might be more than one, but they just need one.

[00:02:12]So, let us look at P. So, P, which is the adrenal gland, produces adrenal adrenaline. So, this one produces what?

[00:02:23]Adrenaline. Adrenaline is known as a flight or fight hormone. And you should make sure that you understand what that means. Okay, in coordination.

[00:02:33]Then, when you talk of Q, which is the pancreas, the pancreas produces insulin.

[00:02:39]Okay? So, this one produces what?

[00:02:41]Insulin.

[00:02:42]So, this is what you needed to answer here. Okay?

[00:02:46]Now, let us come to the second question.

[00:02:48]That is of the third question, by the of A.

[00:02:51]Explain how the hormone produced by P, stated in A1 A2 above, plays a role in coordination. So, how does the one that is produced by P is actually adrenaline. How does How does this adrenaline play the role in coordination? So, when you talk of coordination, we are just looking at how the body parts around communicate. So, when this one is produced, how it plays a role in coordination, like I said, is a flight and fight hormone. So, how this one plays a role in coordination? What is that? So, three marks, look at that. So, it means you need to give about three points.

[00:03:31]So, let me see how you can answer this one, but at least I've given you a clue.

[00:03:36]How this prepares the body for action, since it's a flight or fight hormone.

[00:03:40]How does it prepare the body for action?

[00:03:43]That is what you look for. So, make sure that you put this one in the comment section. How do you answer it? Okay.

[00:03:49]Now, let me help out the last question, which is B. Explain the other role played by gland Q, apart from producing hormone. Now, when you talk of this gland, is an endocrine gland, but also exocrine. Okay? So, in the endocrine system, it plays a role in sugar regulation by producing insulin. You know that insulin is produced when you have higher sugar level to bring it to the normal level.

[00:04:16]That is about insulin. But also it plays a role in digestion.

[00:04:21]In digestion, so explain other other role that gland P, apart from producing hormone. So, we can say produces produces pancreatic It produces pancreatic juice, which contain which contain trypsin, pancreatic amylase, pancreatic amylase, lipase.

[00:05:01]So, which break which break down proteins, break down proteins, carbohydrates, and lipids. So, in other words, what I'm trying to say is that in digestion, this one produces pancreatic juice. In the pancreatic juice, you find trypsin.

[00:05:30]You find pancreatic amylase and lipase.

[00:05:32]The trypsin break down proteins to peptides. Then pancreatic amylase break down carbohydrates to maltose. This one break down fats or finishes up the breakdown of fats into fatty acid and glycerol. So, that is the role it plays in what?

[00:05:49]In digestion. And just like that, you are given a two marks. So, these three marks, I want to see how you can answer that question. Okay, this is what I wanted us to answer.
