Ross and Wilson Pocket Reference Guide to Anatomy and Physiology E-Book

Book Preface

This portable revision aid has been translated from a French volume by Anne Muller, and is designed to be a user-friendly, concise source of information. Its systematic, clear and well-illustrated content is drawn from the best-selling Ross and Wilson Anatomy and Physiology in Health and Illness publications, although it can also be used as a stand-alone resource to complement alternative textbooks. Whatever your anatomy and physiology learning needs are, we hope you find this book a convenient and helpful asset, and we wish you success in your studies.

Comments

Anatomical: There are two anatomically separate vascular systems. The pulmonary circulation—or the lesser circulation—carries blood from the right heart to the lungs and includes the pulmonary arteries and veins. The systemic circulation—or the greater circulation—carries blood from the left heart to the rest of the body and includes the aorta and its branches, as well as the venae cavae and their tributaries.
Physiological: The blood is the mode of transport of oxygen and carbon dioxide between the lungs and the cells of the body. In the lungs, where gas exchange occurs in the alveolar sacs, the blood extracts oxygen and releases carbon dioxide. The blood flowing to the organs of the body is rich in oxygen and nutrients, which are picked up by the cells of the body as they release their waste products into the blood for excretion.
Clinical: The arterial systolic pressure is higher in the systemic circulation. The colour of the skin and of the nails, whether pink or blue, reflects the functional state of the vascular and respiratory systems.
