In this video, we have an example problem that says if liposuction procedures remove adipose tissue, then why do patients report gaining weight back? And we've got these four potential answer options down below. And so it is true that liposuction surgery or procedures remove adipose tissue. However, they do not remove all of the adipose tissue because some adipose tissue is critical for the healthy functioning of the body. And so the adipose tissue that remains is still capable of growing even after a liposuction procedure. But recall that the adipocyte or fat cells do not grow in the traditional sense through cell division, like most other cells do and instead mature adipocyte grow in terms of their size rather than growing through cell division. And so after a liposuction surgery or procedure, if the patient doesn't maintain a healthy lifestyle, including a healthy diet and regular exercise, it is possible for the adipocyte and the remaining adipose tissue to grow in their size. And so notice answer option A says because adipocyte undergo cell division and again, mature adipocyte don't really grow via cell division like other cells typically do. And so for that reason, we can eliminate answer option. A option B says that because adipose tissue is avascular, but recall that adipose tissue is actually highly vascularized, which means that it has a lot of blood vessels. And so to say that it is avascular is incorrect. Then notice that answer option D says because adipose tissue holds more water. But we know adipose tissue has mostly adipocyte which have lots of lipid droplets and lipids are hydrophobic or water fearing. And so that is not going to be a feature that allows this tissue to hold more water. And so for that reason, we can eliminate option D. And so of course, answer option C here is going to be the correct answer which says that because adipocyte can increase in their size. And again, that is going to be the correct answer here. So c here is correct and that concludes this example. So I'll see you all in our next video.
