What is inflammation? How does it protect the body? Why is inflammation considered part of the innate immune response?

Accepted Answer

Hello everyone. Let's look at our next question during an inflammatory response. Which of the following chemicals is released by mast cells. Let's recall from our content videos during the inflammatory response mast cells release histamine. It's a chemical signal that constricts blood vessels that reduces blood flow and loss. So let's find that here and we see the histamine is choice be let's walk through our other answer choices to understand why they're not correct. Um We've got choice A. Which is dopamine and dopamine is a neurotransmitter that acts as a chemical messenger between the neurons it's produced in the brain. So that's not our answer choice there. Now we move on to Choice C. Which is adrenaline and adrenaline as we can kind of guess by the name is released by the adrenal glands. Let's take that out there and it helps to prepare the body for fight or flight response. That sort of its main main function but that is not what we're looking for. So we'll eliminate choice. See and finally we have choice D oxytocin and oxytocin is the hormone that causes the uterus to contract to facilitate childbirth. And it's produced by the hypothalamus in the brain and then released into the bloodstream by the pituitary gland but not what we're looking for. So we can eliminate that. So again during an inflammatory response which of the following chemicals are released by mast cells. And that's Choice B. Histamine. And if you need a little way to remember that. You can think of the fact that if you're having an allergy attack. You might take an anti histamine to stop that. So just one way to keep track of that, see you in the next video.
