The Immune System

Paul Andersen explains how your body protects itself from invading viruses and bacteria. He starts by describing the nonspecific immune responses of skin and inflammation. He then explains how we use antibodies to disrupt the function of antigens and mark them for destruction. He then explains both the homoral and cell-mediated immune response highlighting the importance of B and T lymphocytes. He finally describes the process of long term immunity.

I used to use your videos to study for AP biology, and now 8 years later I am using them to refresh my memory for the lecturing I do at university. Thank you so much for your videos!

[@WhyMunch69]

I watched him during chemo, to help understand what was going on in my body, and what the reaction would be from different systems. And now for 11th grade biology.

To be honest I prefer your videos over the popular Crash Course videos, because I think you are very clear! Thanks so much for all the videos I've already watched for my biology finals!!!

[@jacktran960]

Jesus christ I've been reading my HIGH SCHOOL biology book for several hours, and I don't understand HOW professors with biology-degrees can use over 50 pages to explain something which you clarify a 100 times better in 14 minutes. Thank you so much for the help!

[@StanislavMudrets]

Probably because they don't expect high school students to actually care enough to read more.

[@coolraceralex]

At 7:58, T cells are not made in the thymus gland. They are matured in the thymus gland; however, they are made in the bone marrow.

Most of the time I didn't get it when It was explained by my teacher and then i watched your videos and in 10 minutes I already understand it (even though my English is not that good) I just wanted to thank you for all the good grades I got by watching your videos!

Hi Paul. Thank you so much for your videos and taking the time for students like myself to learn so much better. I was wondering if you also do videos on how experiments, such as ELISA, PCR etc. experiments work, like more of a general idea?
