The lymphatic ___________ return fluid to the cardiovascular system, the lymphoid organs primarily aid __________ function, and ___________ absorb fats that are too large to fit into capillaries.

So here we have a practice problem that wants us to choose one of the 4 potential answer options down below that best fills in these 3 interactive blanks in this sentence, which reads that the lymphatic blank return fluid to the cardiovascular system. The lymphoid organs primarily aid blank function, and blank absorb fats that are too large to fit into capillaries. Now notice that for this first interactive blank, the options are either organs or vessels. And, of course, recall from our previous lesson videos that it's the lymphatic vessels that are important for fluid balance, and they will return lost fluids from the cardiovascular system back to the cardiovascular system. And the lymphatic organs on the other hand, which we'll get to talk more about moving forward in our course, are not so much involved in this fluid balance, and they're more involved in immune functions. And so what this means is we can eliminate answer option a, which suggests that organs would go into this first interactive blank. Now moving on, the next blank says, the lymphoid organs primarily aid blank function. And notice that the options are either immune or fluid balance. Now, again, these lymphoid organs, which we'll get to talk more about moving forward in our course, are not so much involved in fluid balance and are more involved in immune functions. And so for this next blank, we know that it must be immune functions. And that means that we can eliminate answer option c, which suggests that fluid balance should go into this 2nd interactive blank. And then last but not least, we have the final interactive blank. So it says, and absorb fats that are too large to fit into capillaries. Now recall that it's the lacteals, which are specialized lymphatic capillaries in the small intestine that absorb dietary fats and lipid soluble vitamins, and so those are otherwise too large to fit into capillaries, and so these lacteals are critically important for absorbing these fat molecules. And so notice that down below, answer option d says lacteals for this third blank, which means that option d is the correct answer to this practice problem. And notice option c says lymphatic vessels. And technically, lacteals are lymphatic capillaries, which are a type of lymphatic vessel, but lymphatic vessels is not the most specific and it's not the best answer option amongst all of these options. And so be sure whenever there's multiple choice to always select the best answer option. So option b is not the best, and, again, option d is the correct answer. So that concludes this practice, and I'll see you all in our next video.
