Storyboard Text
- Ted was playing basketball at the local court one day. After shooting around for a bit. He began to sweat uncontrollably.
- This allowed his skin to filter toxins from his body and cool him down, allowing him to maintain homeostasis.
- After Ted fell. His first layer of protection kicked in. His physical barrier. Which was his skin. The physical barriers job is to protect our body from microbes from reach sites of potential infection.
- Ted tripped and cut himself on the jagged pavement due to his untied shoes. Blood started gushing out of his cut. So he limped home.
- Ted had no idea what was happening with his knee at the time. His immune system kicked into high gear. It was starting to restore Ted's damaged knee to its original condition.
- After Ted had returned home. He cleaned himself up. Then examined his cut, he noticed that his knee was inflamed. This was due to bacteria infiltrating his injury.
- Because his knee was inflamed, his body's marcophages acted as waste pickers, removing cellular debris and dead cells. Suppressor T cells suppresses the cell-meditated immune system response to an antigen to ensure that healthy tissues are not destroyed in the process.
- Since teds knee was inflamed. killer t cells activated. producing interleukin. This in turn intensified the immune systems defences.
- A couple days later, Ted's wound began to heal, leaving a scab. The b cells, which produce antibodies, were used to create this. Antibodies cling to antigens in order to eliminate them from the body.
- A major part of all of these cells working is from the helper T cell. It gives off a chemical reaction when it detects antigens. This stimulates certain immune cells (macrophages, B cells, and other T cells) to perform their respective functions.
- in case another infection of this kind happens again. Memory T cells are on stand by to ensure a better response to beat the infection.
