How We Fight Off Infections | Secrets Of The Human Body | BBC Earth Science

Our bodies are equipped to fight off all the harmful pathogens we breathe in every day. The lymphatic system has an outstanding way of protecting us. It remembers what pathogen our body has fought off before and it sends suitable killer cells to fight the threat out of our system.

The body is simply amazing.

I use my bare hands and sharpened teeth to fight infection

planning to do a masters in immunology next year after i finish my undergrad in biomolecular science. its so interesting!

[@alanmelendez2633]

Good luck bro! Use your education to help others please! God bless you!

[@ArthurHuizar]

Hope it's going well. 🙏

Good luck!! It is is so interesting!

HI

[@vikas]

Is that Tiff Needell from Fifth gear narrating?

[@123qwe321ify]

Also does anyone know if the "killer" cells target the infection or just kinda kill everything in their path ?

[@kingpuppet5881]

just the infection.

[@joelalarcon3738]

in a viral infection, a virus enters a healthy cell and takes command, healthy cells have molecules on their surface called “antigen” if a virus takes command of a healthy cell, the healthy cell produces the antigen of the virus when killer t cells recognize viral antigen, it tells the killer cell to kill the virally imfected cell healthy cells don’t produce viral antigen, killer cells just targets cells with viral antigen.

Not me watching this video at 3 am sleepless due to a cold virus 😑

😮

[@Ireallylikeeggs]

what I'm saying is I don't know what this video is on about because it's radically different from my day to day experiences and I appreciate the alternative viewpoint

[@NicholasMoreau]

Your day to day experiences? No one "experiences" their cells moving about. Just because you don't see it, doesn't mean it isn't happening in your body.

[@Ireallylikeeggs]

Maybe you don't but I do and I fight with and for them

[@JasonMomos]

[@The_Unknown_Baron]

If the immune system actually did it's job you wouldn't get sick in the first place

[@nesseihtgnay9419]

No that's how I defend against infection. I don't know about the rest of you guys, but that's how my body does it.

[@richricogranada9647]

I just dropped oregano oil in my water, while watching this video, to help fight infection in my body. OO was supposed to be natural antibiotic.

[@asiangirl5947]

Naaaaaa

[@richmahogany1710]

were those shots of the cells at 0:30 real or rendered?

[@ajossi]

Are you serious?

[@Ireallylikeeggs]

Both

[@Ireallylikeeggs]

Someone took a picture of cells and then they printed out the picture and filmed it

[@fidelcatsro6948]

Amazing gift of the Creator!

[@jamesbarry1673]

Yes, thank you mother nature.

Thank You to the Evolution.

[@richricogranada9647]

We need more antibiotics to fight diseases that are antibiotic resistant.

Consider the following: a. I am a human as defined by humans. b. I am an energy based quarkelectronian as modern science claims that all matter is made up of quarks, electrons and interacting energy and I am made up of matter and interacting energy. c. I am a being of 'light', 'if' my current theory of everything is correct whereby the 'gem' photon is the energy unit of this universe that makes up everything in this universe, including space, time and numbers. (Currently dependent upon the results of my gravity test). d. "I" do not even actually exist but eternally existent space time exists as "me", currently in the forms as above. * I exist and yet "I" simultaneously do not exist, dependent upon perspective. But yet, do "I" not truly exist in absolute truth reality as only eternally existent space time exists as all things in absolute truth reality? * "I" can mentally change between perspectives thereby experiencing existence from those various perspectives. "My" mind continues to expand, but is it truly 'my' mind that is expanding or is it eternally existent space time's mind that is expanding? In absolute truth reality, it would seem to be the later.
