This video, we're going to talk a little bit more about acute inflammation. And so recall from our previous lesson video that acute inflammation is characterized by a short-term immune response where symptoms develop very quickly and last a short period of time. For example, just a few days. Now, acute inflammation is characterized by an abundance of neutrophils. And so these neutrophils are going to be in the infected and damaged area. And so the goal of acute inflammation is to quickly recruit immune cells to the location of damage or infection. Once again, neutrophils are going to be recruited first. And so these neutrophils are the first to arrive at the site of infection.
If we take a look at our image down below on the left-hand side, we're focusing on our map of the lesson showing the innate effector actions. We've already discussed phagocytosis, so here in this video, we're focusing on acute inflammation. Here we have a little cartoon that's focusing on acute inflammation. And notice that we have a person outside, and then a bug lands on this person, like a mosquito. Then notice that this person is saying, "Ow, a bug bit me," and the mosquito bit them and notice that acute inflammation is resulting from the bug bite. Just a few days later, notice that the inflammation is gone. And so, notice that acute inflammation only lasts a short period of time, again just a few days.
This here concludes our brief lesson on acute inflammation, characterized by an abundance of neutrophils. Again, we'll be able to apply these concepts as we move forward, and then we'll talk a little bit about chronic inflammation. So I'll see you all in our next video.
