Blood Vessels and Lymphatics on Organ Systems provides an introduction to the general and the specific characteristics of blood vessels and lymphatics in organ systems. It offers a structured, multidisciplinary approach to the broad field of vascular science, emphasizing both established and recent concepts. These include vascular networks such as those in the pineal, parathyroids, pancreas, adrenals, adipose tissue, and special senses; and functions of vascular endothelium. The book is organized into two parts. Part One on the general properties of blood vessels and lymphatics deals with th ...
Lymphatic Structure and Function in Health and Disease serves as a resource book on what has been learned about lymphatic structure, function and anatomy within different organ systems. This is the first book to bring together lymphatic medicine as a whole, with in-depth analysis of specific aspects of lymphatics in different vascular pathologies. This book is a useful tool for scientists, practicing clinicians and residents, in particular, those in vascular biology, neurology, cardiology and general medicine. Chapters discuss topics such as ontogeny and phylogeny of lymphatics, lymphatic pumping, CNS lymphatics, lymphatics in transplant and lymphatic reconstruction. - Brings together lymphatic medicine as a whole, with an in-depth analysis of the specific basic science aspects of lymphatic structure and function - Covers the clinical aspects of lymphatics in different vascular pathologies - Co-published with the International Society of Neurovascular Diseases - Discusses lymphatic structure and function in all of the major organ systems
This presentation describes various aspects of the regulation of tissue oxygenation, including the roles of the circulatory system, respiratory system, and blood, the carrier of oxygen within these components of the cardiorespiratory system. The respiratory system takes oxygen from the atmosphere and transports it by diffusion from the air in the alveoli to the blood flowing through the pulmonary capillaries. The cardiovascular system then moves the oxygenated blood from the heart to the microcirculation of the various organs by convection, where oxygen is released from hemoglobin in the red blood cells and moves to the parenchymal cells of each tissue by diffusion. Oxygen that has diffused into cells is then utilized in the mitochondria to produce adenosine triphosphate (ATP), the energy currency of all cells. The mitochondria are able to produce ATP until the oxygen tension or PO2 on the cell surface falls to a critical level of about 4–5 mm Hg. Thus, in order to meet the energetic needs of cells, it is important to maintain a continuous supply of oxygen to the mitochondria at or above the critical PO2 . In order to accomplish this desired outcome, the cardiorespiratory system, including the blood, must be capable of regulation to ensure survival of all tissues under a wide range of circumstances. The purpose of this presentation is to provide basic information about the operation and regulation of the cardiovascular and respiratory systems, as well as the properties of the blood and parenchymal cells, so that a fundamental understanding of the regulation of tissue oxygenation is achieved.
The partition of fluid between the vascular and interstitial compartments is regulated by forces (hydrostatic and oncotic) operating across the microvascular walls and the surface areas of permeable structures comprising the endothelial barrier to fluid and solute exchange, as well as within the extracellular matrix and lymphatics. In addition to its role in the regulation of vascular volume, transcapillary fluid filtration also allows for continuous turnover of water bathing tissue cells, providing the medium for diffusional flux of oxygen and nutrients required for cellular metabolism and removal of metabolic byproducts. Transendothelial volume flow has also been shown to influence vascular smooth muscle tone in arterioles, hydraulic conductivity in capillaries, and neutrophil transmigration across postcapillary venules, while the flow of this filtrate through the interstitial spaces functions to modify the activities of parenchymal, resident tissue, and metastasizing tumor cells. Likewise, the flow of lymph, which is driven by capillary filtration, is important for the transport of immune and tumor cells, antigen delivery to lymph nodes, and for return of filtered fluid and extravasated proteins to the blood. Given this background, the aims of this treatise are to summarize our current understanding of the factors involved in the regulation of transcapillary fluid movement, how fluid movements across the endothelial barrier and through the interstitium and lymphatic vessels influence cell function and behavior, and the pathophysiology of edema formation.

The placenta is an organ that connects the developing fetus to the uterine wall, thereby allowing nutrient uptake, waste elimination, and gas exchange via the mother's blood supply. Proper vascular development in the placenta is fundamental to ensuring a healthy fetus and successful pregnancy. This book provides an up-to-date summary and synthesis of knowledge regarding placental vascular biology and discusses the relevance of this vascular bed to the functions of the human placenta.
The endothelium, a monolayer of endothelial cells, constitutes the inner cellular lining of the blood vessels (arteries, veins and capillaries) and the lymphatic system, and therefore is in direct contact with the blood/lymph and the circulating cells. The endothelium is a major player in the control of blood fluidity, platelet aggregation and vascular tone, a major actor in the regulation of immunology, inflammation and angiogenesis, and an important metabolizing and an endocrine organ. Endothelial cells controls vascular tone, and thereby blood flow, by synthesizing and releasing relaxing and contracting factors such as nitric oxide, metabolites of arachidonic acid via the cyclooxygenases, lipoxygenases and cytochrome P450 pathways, various peptides (endothelin, urotensin, CNP, adrenomedullin, etc.), adenosine, purines, reactive oxygen species and so on. Additionally, endothelial ectoenzymes are required steps in the generation of vasoactive hormones such as angiotensin II. An endothelial dysfunction linked to an imbalance in the synthesis and/or the release of these various endothelial factors may explain the initiation of cardiovascular pathologies (from hypertension to atherosclerosis) or their development and perpetuation.

Blood Vessels and Lymphatics on Organ Systems provides an introduction to the general and the specific characteristics of blood vessels and lymphatics in organ systems. It offers a structured, multidisciplinary approach to the broad field of vascular science, emphasizing both established and recent concepts. These include vascular networks such as those in the pineal, parathyroids, pancreas, adrenals, adipose tissue, and special senses; and functions of vascular endothelium. The book is organized into two parts. Part One on the general properties of blood vessels and lymphatics deals with the general aspects of the arteries, veins, microcirculation, and lymphatic channels. Part Two discusses the embryologic, morphologic, physiologic, pharmacologic, pathophysiologic, and pathologic characteristics of blood and lymph circulations in each of the important organ systems. This book was written for graduate students in the areas of blood and lymph circulation and for advanced research workers or clinicians seeking sources of information on advances in cardiovascular science.
An understanding of the structure and function of the human body is vital for anyone studying the medical and health sciences. In this book, Leslie Klenerman provides a clear and accessible overview of the main systems of the human anatomy, illustrated with a number of clear explanatory diagrams.
