دانلود کتاب Intestinal Absorptive Surface in Mammals of Different Sizes

This treatise combines a detailed methodology that is simple to follow and reconstruct, and can be universally used to determine the surface area or tubular organs, in this special case development for the intestines. It is especially appropriate for large intestine, but can be used for small intestine also. The great advantage is the applicability at the macroscopic and microscopic levels, measuring the entire intestine for determination of a ground or basal area, and using a large encompassing sampling technique to obtain a factor of surface enlargment due to such structural entitities as folds and plicae. A technique to determine the factor of increase due to microvilli is also introduced. Various factors that may influence the measurements are discussed. Application of the technique is presented within the concept of scaling. Numerous regression curves are presented to represent how intestinal surface area correlates with body weight. A unifying and correlating concept between morphology and morphometry is developed. Over 20 species are included.
