White blood cells [🔬 oneminmicro]

Out of all the things I've seen in science this one boggles my mind the most. Even more than the brain. It's completely insane how advanced the inherent bio-tech that we're getting born with really is. This is INSANE! More so because we can't synthesize artificially even in our most advanced labs not even ONE of these things. NOT ONE! And our body generates hundreds of thousands of these with immaculate accuracy every day of every week of every month of every year of every decade of our lives. Man! PS: It's these kinds of phenomena that remind me of that saying "the things we think we know are less than a droplet - but the things we DON'T know DWARF even the most Avast, immeasurable oceans"

All in Christ Jesus use all their blood, spirits, souls ask Yahweh that permanently Elise Oyinkromeineifa's body stops struggling to retain blood, produce new blood cells and all works not of Christ on her blood, liver, plasma we curse, stop now invoking the name of Jesus Christ

They digest it and present parts in the lymph nodes to other immune cells called T and B cells to build up memory (CD4 T cells) and weapons if the pathogens come again (CD T8-cells, antibodies B-cells) Source: I am a doctor and had to learn that shit once upon a time.

Isn't white and red blood cells supposed to be oval in shape

O 😲 my god

Fascinating glimpse into white blood cell analysis!

This is fascinating to watch. I'd love an eli5 on this. Do the cells conciously seek out the pathogens? Can they detect them? How are the pathogens broken down? (I can't imagine white blood cells have a digestive tract.) Can they grab and consume any pathogen if it is just a case of physically reaching out and enveloping it?

Fun fact: White blood cells are like your body's superheroes! There are several types, including neutrophils, which act like first responders to infection, and lymphocytes, responsible for long-term immunity. They work together to keep you healthy! 🦸‍♂️💪

Amazing

I’ll try to give an ELI5 for your questions to the best of my ability, most my info comes from reading Kurzgesagts book on the subject “immune”, forgive formatting as I’m on my phone. Firstly white blood cells is a horrific term, it is useful to keep things simple but if you want to know more it’s just confusing. The video looks like macrophages, these are your run of the mill soldier cells, they eat pathogens and just anything that they believe shouldn’t be there, like tattoo ink. Your cells obviously can’t see because they have no eyes, some cells have photoreceptors but not in this case, your cells move around by “smelling” with their receptors, cytokines are basically bits of information that are everywhere in your body, they are proteins that tell in this case, your immune cells, what’s going on, for example, cells are dying in the wrong way because of an infection. The more cytokines, the closer you are to the issue and so the cell "knows" where to go. cells do have sort of a digestive system, in eukaryotic cells (animal, plant and fungi cells) these are Lysosomes, now I’m not sure of the differences of a macrophage specifically but yes, these lysosomes eat stuff, they digest nucleic acids and proteins and for macrophages, they eat anything they can get their hands on. By the way, macrophage literally means large eater, one of the few good names of immunology. Macrophages eat dead cells, detritus and yes, pathogens, they only eat viruses that are outside of the cell as killer T cells are the main ones that kill infected cells, but if they grab something that isn’t part of your body (how this is determined is a whole other story, I’d suggest reading immune if you are interested) it pulls it into itself and basically pushes it to its stomach and digests it. Other immune cells attack in different ways but that’s the basics from my limited knowledge training as a nurse and as an interested reader.
