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.

Secrets of the Human Body (2017)
The human body is the most sophisticated organism on earth. It's a scientific marvel and much about it remains a mystery. Secrets of the Human Body uses cutting-edge graphics to effectively peel back the skin and reveal the surprisingly beautiful biological processes that keep us alive.

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

[anactualmango_]

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

[Jaime-epce]

Great information..well done...thank you...\m/

[Arkkukie]

I can't believe there's a Chad live inside my body, i love my body and i will make sure all Civilians inside my body live safe

[qweify]

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

[nesseihtgnay]

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.

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.

Turning green to red just seemed odd... 😅

[richmahogany]

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

[ahahahahaha]

Why does it take a few days/ week for the antibodys to fully kill the cold?

[vikas]

Is that Tiff Needell from Fifth gear narrating?

[richricogranada]

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.

A old lady taking off her clones? Bruh

[Baron_of_Gaming]

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

[richricogranada]

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