I didn't know there were so many... somebody explain... en-us 2017-02-28 19:12:17 UTC 2025-11-14 22:37:32 UTC hello@padlet.com https://padlet-assets.storage.googleapis.com/portrait/monkey.jpg https://padlet.com/jhitchings/c38ftp8dovk0/wish/157515937 Well now Im surprised to see there are no entries yet!

They can send a signal to ask a capillary to open a gap between cells and then can move through the cells to the site of the infection.]]> 2017-03-03 04:38:32 UTC https://padlet.com/jhitchings/c38ftp8dovk0/wish/157533498 https://padlet.com/jhitchings/c38ftp8dovk0/wish/157584044 I didn't know that Acquired Immunity develops more slowing and requires the body to learn the ways of the pathogen before it defeats it. Also, only vertebrates have the acquired immune system.]]> 2017-03-03 12:08:26 UTC https://padlet.com/jhitchings/c38ftp8dovk0/wish/157584044 https://padlet.com/jhitchings/c38ftp8dovk0/wish/157660217 I did not know that histamine triggers an immune response which is responsible for inflammation]]> 2017-03-03 16:24:43 UTC https://padlet.com/jhitchings/c38ftp8dovk0/wish/157660217 https://padlet.com/jhitchings/c38ftp8dovk0/wish/157902255 These videos taught me the differences between T cells and B cells. T cells kill infected cells that contain the pathogen and B cells produce antibodies that tag the antigen so that they can be identified better as being harmful and slowing them down from being infectious.]]> 2017-03-06 01:17:48 UTC https://padlet.com/jhitchings/c38ftp8dovk0/wish/157902255 https://padlet.com/jhitchings/c38ftp8dovk0/wish/157907397 It was interesting to learn about the different chemical signals that initiate the inflammatory response such as histamine, which makes blood vessels more permeable and allows fluid to flow to the affected area. Also, histamine brings in many white blood cells to help fight off the infection.]]> 2017-03-06 02:05:15 UTC https://padlet.com/jhitchings/c38ftp8dovk0/wish/157907397 https://padlet.com/jhitchings/c38ftp8dovk0/wish/157912787 I didn't know that there are
 2 types of immunity the innate immunity and the acquired and it was cool to see that they both were different and worked in different or more specific ways]]> 2017-03-06 03:12:13 UTC https://padlet.com/jhitchings/c38ftp8dovk0/wish/157912787 https://padlet.com/jhitchings/c38ftp8dovk0/wish/157914506 I didn't know that technically your digestive tract is also on the outside of your body.

T Cells are made in the thyroid and B cells are made in bone marrow. T cells are the only cells that kill human cells, cells that are not foreign to the body, but are infected. ]]> 2017-03-06 18:22:02 UTC https://padlet.com/jhitchings/c38ftp8dovk0/wish/158122707 https://padlet.com/jhitchings/c38ftp8dovk0/wish/158179596 I was surprised to learn how extensive and specialized the immune system is. There are so many types and different ways to defend against disease and infection, such as macrophages and dendritic cells.]]> 2017-03-06 21:08:58 UTC https://padlet.com/jhitchings/c38ftp8dovk0/wish/158179596 https://padlet.com/jhitchings/c38ftp8dovk0/wish/158548146 I didn't realize that there were 2 different kinds of immune systems, innate and acquired. I also didn't know that t cells were part of the cell mediated response and the b cells were part of the humoral response or that there were different responses to begin with.]]> 2017-03-08 03:04:26 UTC https://padlet.com/jhitchings/c38ftp8dovk0/wish/158548146
