The process by which neutrophils squeeze through capillary walls in response to inflammatory signals is called

a. diapedesis,
b. chemotaxis,
c. margination,
d. opsonization.

Accepted Answer

Hi everybody. Here's our next problem which of the following statements, accurately describes the process of diapedesis. A it is the process of marking pathogens or foreign particles or destruction by immune cells often through the attachment of opsonin such as antibodies or complement proteins to the surface of the pathogen. B. It refers to the process of movement of macrophages by forming cytoplasmic extensions. C it is a process by which neutrophils and other white blood cells squeeze through the capillary walls and enter the surrounding tissue in response to inflammatory signals or d it refers to the directed movement of cells in response to chemical signals or gradients that allow cells to navigate and respond to their environment. So this is a very wordy one, but we're looking for the definition of diapedesis. And that is choice c the process by which neutrophils and other white blood cells squeeze to the capillary walls to get to the surrounding tissue. And key to remember this is leaving the cell walls intact. It's how they get through and move around and get to the site uh where they need to act in terms of inflammation, infection. Other things when we look at our other answer. Choices, both B and D. So process of the movement of macrophages by forming cytoplasmic extensions. And D referring to the directed movement of cells in response to chemical signals or gradients describe the process of chemotaxis, not the process of diapedesis. So, chemotaxis is what allows cells to navigate around, move around in response to chemical signals and they do that by forming cytoplasmic extensions, but it's not diapedesis. So B and D are not a correct answers. And finally choice. A, the process of marking pathogens or foreign particles for destruction is not diapedesis. But and we have that clue for us in that answer. And then it says that that process of marking is often through the attachment of opsonin. So attachment of opsonin like antibodies or complement proteins is the process of ization, not diabetes. So choice A is not our answer. So again, accurately describing the process of diapedesis. Choice C the process by which neutrophils and other white blood cells squeeze to the capri layer walls and enter the surrounding tissue in response to inflammatory signals. See you in the next video.

The process by which neutrophils squeeze through capillary walls in response to inflammatory signals is called a. diapedesis, b. chemotaxis, c. margination, d. opsonization.
