ANATOMY & PHYSIOLOGY
Understanding Anatomy & Physiology for High School A Visual, Auditory, Interactive Approach, 3rd Edition Gale Sloan Thompson, RN How do your students learn A&P best? Whatever their learning style…by reading, looking, or doing, or a little bit of each…here’s a visually oriented approach that is designed just for them. Tackle a tough subject in bite-sized pieces. A seemingly huge volume of information is organized into manageable sections to make complex concepts easy to understand and remember. Each unique page spread provides an entire unit of understanding, breaking down complex concepts into easy-to-grasp sections for today’s learner. Full- color illustrations, figures, sidebars, helpful hints, and easy-to-read descriptions make information crystal clear. § “Making It Work” sections introduce students to the many exciting careers across a wide spectrum that begin with a firm foundation in A&P. § “That Makes Sense” boxes increase retention with mnemonics & hints. § “Life Lesson” boxes show how A&P relates to daily living. § “The Body AT WORK” explains specific physiological processes.
The atrioventricular (AV) valves regulate flow between the atria and the ventricles. ● The right AV valve—also called the tricuspid valve (because it has three leaflets)—prevents backflow from the right ventricle to the right atrium. ● The left AV valve—also called the bicuspid valve (because it has two leaflets), or, more commonly, the mitral valve —prevents backflow from the left ventricle to the left atrium.

The Heart Skeleton A semi-rigid, fibrous, connective tissue called the skeleton of the hear offering support for the heart, the skeleton keeps the valves from stretc insulating barrier between the atria and the ventricles, preventing elect the ventricles other than through a normal conduction pathway.

The Body at Work—Brief summaries explain physiological processes.
Skeleton of heart, including fibrous rings around valves Mitral valve
The Body AT WORK Valves open and close in response to pressure changes within the heart. For example, when a ventricle relaxes, the pressure within that ventricle drops. The AV valve leaflets hang limply, allowing blood to flow through the open valve into the ventricle. As the ventricle fills, pressure in the ventricle rises. After filling, the ventricle begins to contract and the pressure rises even more. This increased pressure pushes against the cusps of the AV valve, causing it to snap closed. When pressure in the ventricle exceeds the pressure “downstream,” the semilunar valve pops open, allowing blood to flow out into the area of lower pressure.
I finally understand A & P! “I can’t say enough good things about this book. The writing is clear and to the point, and colorful charts and figures take it a step further by illustrating key processes. —Bobby T., Online Reviewer
