A Photographic Atlas for the Biology Laboratory, Fourth Edition is designed to provide you with quality photographs of organisms, similar to those you may have the opportunity to observe in a biology laboratory. It is designed to accompany any biology text or laboratory manual you may be using in the classroom. In certain courses, this photographic atlas could serve as the laboratory manual. An objective of this atlas is to provide you with a balanced visual representation of the five kingdoms of biological organisms. Great care has been taken to construct completely labeled, informative figures that are depicted clearly and accurately. Because A Photographic Atlas for the Biology Laboratory, Fourth Edition is presented in full-color, the specimens depicted in this atlas appear as you see them in the biology laboratory. The terminology used in this atlas is that which is found in the more commonly used college biology texts. Also, Chapter Eight of this atlas is devoted to the biology of the human organism, providing a complete set of photographs for each of the human body systems. Human cadavers have been carefully dissected and photographed to clearly depict the principal organs from each of the body systems. Selected radiographs (X-rays), CT scans, and MR images depict structures from living people and thus provide an applied dimension within this portion of the atlas. We hope you’ll be pleased with this brand new edition of our ever popular atlas. A Photographic Atlas for the Biology Laboratory, Fourth Edition was revised to include updated photographs, a new interior design, updated terminology, and more extensive sections on the rat and the fetal pig.
