a. Describe the appearance of platelets and state their major function. b. Why should platelets not be called 'cells'?

Video transcript

Everyone. Let's take a look at this question together which of the following are large nucleated cells that are the initial precursors to platelets. Is it answer choice. A mega Carob blast answer choice B mega Caro site, answer choice C thrombocytes or answer choice D leucocytes. Let's work this problem out together to try to figure out which of the following are the initial precursors to platelets. So looking at the question before we can break it down to try to figure out the correct answer, we know that we can go ahead and eliminate answer choice D leucocytes since we know that those are just the white blood cells which are not involved in the production of platelets. So it is incorrect, leaving us with three remaining answer choices. And we can recall when it comes to the production of platelets, we know that the cells that are responsible for the production of the platelets are the mega Caro sites which we can see is an answer choice and answer choice B. However, we are looking for that initial precursor. So we want the precursor to those mega Caro sites and we know that the large nucleated cell that are the initial precursors to the mega Caro sites are the mega Caro blasts, which is answer choice. A the correct answer since they are those large nucleated cells, who are the initial precursor to the mega Caro sites, which we know are involved in the production of those platelets. Making answer choice. A the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
