Funny way to describe "Memory T Cell role in the immune system ! 😂😂 Memory T cells are a subset of infection- and cancer- fighting T cells (also known as a T lymphocyte) that have previously encountered and responded to their cognate antigen; thus, the term antigen-experienced T cell is often applied. Such T cells can recognize foreign invaders, such as bacteria or viruses, as well as cancer cells. Memory T cells have become "experienced" by having encountered antigen during a prior infection, encounter with cancer, or previous vaccination. At a second encounter with the invader, memory T cells can reproduce to mount a faster and stronger immune response than the first time the immune system responded to the pathogen that entered the body. This behaviour is utilized in T lymphocyte proliferation assays, which can reveal exposure to specific antigens.

Removing a solid piece of silicone lip implants!! 👄👄 Lip implants are often removed or rather replaced once they start to become uncomfortable and noticeable for example when a patient smiles and their edges can be seen. They are removed or pulled through an incision made under the lip so scarring isn't visible while healing.

Baby born while still encased in a fully intact amniotic sac!! This fluid-filled sac cushions the fetus, permits fetal lung growth, provides a barrier against infection and allows the fetus to move freely Seeing an en-caul birth can be jarring at first, but it is ultimately harmless and easily removable. So in the video, where it balloons out, you can make out the most adorable little hands, about to be brought out into the world. Doctors manually pierce the membrane causing it to burst and remove the child from the sac.

😮 This is a tiny little foot of a 14 week old fetus. This was a case of a spontaneous miscarriage that ended up this way due to pregnancy complications. But the truly amazing thing here is what we start from, what life starts from. This small foot isn't even fully developed, blood vessels aren't all functional, bones are soft, skin is thin, and the different nerves of the foot still developing, so legs still have a bit more growing to do. During many miscarriages and/or D&Cs (Dilation & curettage surgical removal of part of the lining of the uterus and/or contents of the uterus by scraping and scooping) the fetus is broken up by clamps to remove it easier. If it is not done this way, it puts the mother at risk for complications resulting in her not being able to conceive again.

Ever wondered what this strange looking contraption is? - It's called the Pigg-O-Stat, and while the name is unfortunate, it was designed for a very important reason. It works as a pediatric immobilization device designed for positioning infants and young children and keeping them still while taking X-rays. Although it looks frightening, it actually limits the amount of time and radiation exposure necessary to get the X-rays.
