The new edition of Award-winning author and educator Dee Silverthorn's Human Physiology: An Integrated Approach builds upon the book's thorough coverage of integrative and molecular physiology topics to give you a solid foundation of understanding for your education, career, or general knowledge. Every piece of art has been revised so that figures and diagrams are clearer, making it easier to understand complex physiological systems. A comprehensive, integrated approach including basic cell processes, homeostasis & control, integration of function, and metabolism, growth, & aging. For college instructors, students, people in the nursing/allied health field, or anyone interested in human anatomy.

An introductory level text for first and second year students in human or animal physiology. The text focuses on developing students' skills by helping them connect facts and concepts and apply them to real-world situations. Included are illustrations of physiological processes.

Intended for health science students, this textbook emphasizes broad concepts and their application to specific problems (as opposed to presenting excessive detail and encouraging rote memorization). Chapters are grouped by biological system, with additional chapters covering cellular physiology and temperature regulation and exercise.

This review and study guide is designed for medical students who are using the Second Edition of Johnson's Essential Medical Physiology in their course work. The review book contains 1,000 questions based on the text, plus answers and discussions. Also included are 62 illustrative drawings, most of them selected from the text. Other user-friendly features include detailed outlines of the chapters of the text and boxed displays containing hot topics or key facts statements.Used in conjunction with Essential Medical Physiology, this review book will stimulate deeper engagement with the text, serve as a guide to key points, and refresh the student's memory before an exam.

Extensively illustrated...a very useful text...definitely recommended for rapid revision before finals as well as for laying one's foundations throughout the course. Worth buying." Cambridge Medicine, Addenbrooke's Clinical Medical School "..a concise, yet complete, textbook on general physiology..an excellent reference for clinicians wanting general information on physiology that is concise and easy to use" Physical Therapy on the 3rd edition "The text is fluent, easy to absorb and most important written very concisely. The style makes it easy to pick out relevant information.

The fourth edition of NMS Physiology , a well respected and heavily used text, is written in an outline format useful to medical students who require a physiology course review and a comprehensive study tool for USMLE preparation. This one-volume, portable text contains 300 USMLE-style questions with answers and explanations. New to the edition are more questions, updated case studies in clinical decision making, concise outlines, and expanded diagrams. Sections devoted to endocrinology, acid-base, and pathophysiology also are especially helpful to students.

This is a colourful, highly illustrated textbook of human physiology aimed at medical students. Organized by systems in the traditional approach used by many physiology texts, the book also offers additional features; the text is succinct, with emphasis on core knowledge, there are clinical application boxes throughout, and each section contains examples of applied physiology to show how systems interact and are dependent on each other. There are multiple choice questions (MCQs) with answers at the end of each section.

This chapter is relevant to Section G4(i) of the 2023 CICM Primary Syllabus, which expects the exam candidate to "describe the essential features of the micro-circulationincluding fluid exchange and its control mechanisms". Multiple past paper questions have explored this topic:

There is, fortunately, no shortage of good literature on this topic. What needs to be said about these concepts is already said there with a maximum economy of words and greatest clarity, and so this chapter mainly acts as something of an ornamental border, framing the works of Erstad (2020), Woodcock (2017), Michel et al (2019), and so forth. Every which way you turn, there is also a high quality FOAM resource, among which Part One, fluidphysiology.org and PulmCCM shine the brightest.

As is often the case, Ernest Starling never called it "my equation", and in fact there was no equation described in the original 1896 paper. The basis of his work was the observation that haemorrhage causes the blood to become more dilute. From this, Starling concluded that there must be some mechanism to allow fluid to move into and out of blood vessels. He made the hind leg of a dog oedematous by the subcutaneous injection of isotonic saline, and then perfused it with some blood of a known haematocrit. The blood, as it emerged from the veins of the dog's leg, had "in all cases absorbed fluid: the whole blood and the serum were more dilute and the haemoglobin percentage was diminished." From his findings, Starling deduced that the capillaries and post-capillary venules behave as semi-permeable membranes absorbing fluid from the interstitial space.

Starling attributed the uptake of water by venules to "molecular imbibition, e.g. the process by which gelatin will take up water and salts from proteid solutions", as the term oncotic pressure had not yet come to common parlance. Unfortunately, he did not have any way to support his idea by measuring it, and the concept itself (at this stage called "high endosmotic equivalent of albumen") was not completely accepted at that stage, or rather blown off as irrelevant by the prevailing winds of physiology literature. As osmometers became more common and reliable, other investigators were able to demonstrate that all aspects of it were experimentally supportable. For example, Eugene Landis in 1926 was able to show that when oncotic pressure and capillary hydrostatic pressure were equal, there was no net fluid movement across the capillary wall. Starling's principle was further developed after his death in 1927 by Krogh, Landis and Turner (1931), who called it "Starling's conception" and by the time Keys et al wrote about "famine edema" in 1946, the equation had become a part of the laboratory furniture.

There are several variants of this equation, which mainly differ in their notation. Ganong (23rd ed) use k to denote the hydraulic permeability coefficient, where it presumably stands for Koefficient. Pappano & Weir use Qf to describe the net fluid transport as flow (Q) of fluid (f). All textbook versions of this formula are otherwise identical, and the trainee would be expected to reproduce this version in their exam answers, even though it might be technically inaccurate (as is discussed at the very end of this chapter). It goes without saying that the technical accuracy of one's answer will be poor comfort to the candidate who failed by that exact number of marks.

Hopefully, this is what the examiners meant by their cryptic statement, "the importance of the relative difference along the length of the capillary" (Question 16 from the second paper of 2018). As one will see later, the last component of this relative difference is somewhat controversial, as modern investigators have not always been able to demonstrate the sort of back-filtration that the Starling equation describes.

Is a question which the college examiners are clearly anxious for you to know the answer to. The examiners insisted on "approximate values and examples of factors that influence them" in their comments for Question 16 from the second paper of 2018, and "numerical values pertaining to hydrostatic and oncotic pressure gradients" in Question 18 from the first paper of 2011. These weirdly specific demands seem to suggest that they were writing the question while looking at a specific page in some textbook where all these numbers are clearly laid out in some sort of figure or table. Fortunately, the abovementioned SAQ comes from a distant long-gone time when time and effort were invested in writing the examiner's comments, and a vague reference to Ganong was left as a breadcrumb for the readers. It leads to the 23rd edition, where on page 548 all of the coveted values are listed:

Where did these come from? The textbook, as is usually the case, does not offer any references. Measurements of these variables pressure along the capillary are obviously going to be different from measurement to measurement, even within the same organism. In short, the trainee is advised to randomly pick a set of values and commit them to memory with the somber knowledge that they are probably wrong.

Capillary hydrostatic pressure is basically the blood pressure, which at the level of the capillaries should be quite low, mainly due to the drop in pressure which is observed at the arterioles. Lots of authors give numbers here, and none are more trustworthy than the others. For instance, Pappano & Weir report a starting capillary pressure of 32 mmHg which drops to 15 mmH in the post-capillary venule. This somewhat differs from Davis et al (1986), who recorded a pressure difference from 25 mmHg to 17 mmHg in their hamsters, and Gore (1974), who got 32-28 mmHg in his cats. Brandis quotes Landis (1930), whose human values were 32 and 12mmHg. This pressure is still sort-of pulsatile, but the pulse pressure is only 1-2mmHg.

Obviously, gravity will play a role here, and hydrostatic pressure will increase in dependent regions, eg. the legs stuffed under economy class seats for many hours. Logically, the effect of gravity is more profound the taller you are, to the point where Hargens et al (2007) report on multiple unique permeability-controlling mechanisms in the lower limbs of the giraffe, designed to prevent them from uncontrollably leaking their whole body fluid volume out into the soft tissues of their legs. For the record, the capillary hydrostatic pressure in the feet of the upright giraffe is probably between 260 and 150 mmHg, compared to something like 90 mmHg in the feet of an upright zookeeper.
