Microvilli are microscopic finger-like projections of the epithelial cells that line the small intestine. In this exercise, you will calculate by how much the microvilli increase the surface area of the small intestine. The increased surface area is an evolutionary adaptation that greatly increases the rate of nutrient absorption.
A single microvillus is a rod-like structure that is 1.0?m in height. It has a hemispherical top approximately 0.1?m in diameter Calculate the surface area of the cylinder that forms the "sides" of the microvillus rod. Use 3.14 for ?. Enter your answer rounded to two decimal places.
Now calculate the surface area of the hemispherical top of the microvillus rod. Use 3.14 for ?. For help, review this tutorial: Calculating the Surface Area of a Sphere. (Remember that the top of the microvillus is only half of a sphere.) Enter your answer rounded to two decimal places.
Now use your answers from Parts A and B to calculate the entire surface area of one microvillus ( in ?m2 ). (Remember that a microvillus is a projection of the intestinal surface, so there is no "bottom" surface.) Enter your answer rounded to two decimal places.
