A. Function is absorption ;Location is nephron
B. Function is absorption ;Location is capillary
C. Function is immune defence;Location is bone marrow
D. Function is insulation;Location is adipose tissue


参考答案:  A


本题详细解析:
Choice A is correct because microvilli are present, increasing the cell's surface area for absorption. Cells of the proximal convoluted tubule in the nephron require a large surface area for selected reabsorption of substances in the filtrate. Choice B is incorrect because cells lining capillaries are flat (squamous epithelial tissue). Choice C is incorrect because cells of the immune system do not have microvilli. Choice D is incorrect because the function of microvilli is not insulation, and adipose cells do not have microvilli.
