Apoptosis | Cell division | Biology | Khan Academy

Learn how apoptosis, or programmed cell death, is different from cell death by injury. We discuss its role in development and body maintenance.

I like to think of it as:
Necrosis: injured or infected cells are blown up, spewing nasty stuff that can hurt other cells.
Apoptosis: ah, it's time to go, let me just neatly pack up my things into little blebs that can be reused.

10 minute video with minimum relevant information on the process.

[@mandisangema3930]

i think one person explaining is fine...

the guy narrator: *mentions leaves falling from a tree analogy*
me: brain no please not now we have a test tomorrow this is serious-
my brain, screaming and in tears: LEAVES FROM THE VINE, FALLING LIKE SNOW

I see that you are cultured. But Uncle Iroh 😭😭

This video deserves billion likes

[@annakarolinapratessperandi5181]

videos in this style are very good!

[@johnbates3567]

This is a really great vid and very clear and informative. I think the dynamic of David asking questions and making a few observations and Emily answering the question works really well. Hope to see lots more vids like this. Thank you.

Wait, Mr. Grammar Guy David does Biology video?!

One of the questions asked...
The answer is Autophagy. Another way the cell breaks down to reuse it's parts...

[@TalhaMahar-r5t]

Very helpful video fabulous

[@nargisadnan7007]

Good explanation

[@tyronearollado4668]

ok where is Sal

So, it's like a recycling plant vs. a land fill, right?

How does apoptosis prevent cancer

[@simrahqaddus7316]

If a cell discovers it has cancerous symptoms, or something has happened to its DNA and the cell is unable to fix the DNA, the cell will undergo apoptosis. By doing this, it is preventing itself from passing on the damaged DNA which could potentially make a cancerous cell.

So what you're saying is that I'm dying inside?

[@christopherlawes6081]

Or being reborn

[@abdelrahmangamalmahdy]

That's cell death not division!

[@domjuandeperon]

sHOW.

[@larsonbergquist8721]

terrible waste of time.
