Transcript of Today’s Episode
Hello and welcome to another episode of Interactive Biology TV where we’re making Biology fun. My name is Leslie Samuel, and in this episode, I’m going to be talking about the four types of cellular adaptations.
Two videos ago, I answered the question, “What is a disease?” And, in the last episode, what I spoke about were the “Five Causes of Disease.” The first cause, the number one cause of disease was adaptation, and what I said was that an adaptation is a cellular reaction to prevent injury. So, there’s an injurious agent in the environment of the cell, and the cell reacts in a way to prevent injury.
You can go back and check out those videos, but in this video, what I want to talk about is the first cause of disease which is an adaptation. So, what we’re going to do is we’re going to talk about the four types of adaptations.
With hypertrophy, we have the tissue increasing in size because the individual cells are increasing in size. In hyperplasia, we have the tissue increasing in size because we’re getting more cells, which make sense.
And, you can say it with me. Let’s say it together.
Number one is atrophy, hypertrophy, hyperplasia, and metaplasia. We can kind of say it together. We can almost dance to it. it’s that simple. So, atrophy, hypertrophy, hyperplasia, and metaplasia.
In the next video, we’re going to go into detail about atrophy, and we’re going to continue from there.
That’s it for this video.
That’s it for this video, and I’ll see you in the next one.
