A number of specialised tissues are important for the proper functioning of the immune system. Among these are the lymph nodes , which provide an ideal environment for communication between immune cells. This environment is necessary for proper activation of the T and B cells or lymphocytes that are required for defence against many pathogens. A number of features of lymph nodes help them to perform their functions. The lymph nodes are strategically located at anatomical locations where they are most able to receive immunological signals from around the body. The total number of nodes is not known, but there are likely to be hundreds.
The lymphatic system is a collection of structures and vessels that drains lymph from blood and has several other functions. It is a circulatory system for lymph fluid and the site of many key immune system functions. The lymphatic vessels are the lymphatic system equivalent of the blood vessels of the circulatory system and drain fluid from the circulatory system. The network of lymph vessels consists of the initial collectors of lymph fluid, which are small, valveless vessels, and goes on to form the precollector vessels, which have rudimentary valves that are not fully functional. These structures then form increasingly larger lymphatic vessels which form colaterals and have lymph-angions lymph hearts. The larger lymph vessels contain valves that prevent the backflow of lymph.
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. Scientists, practicing clinicians and residents, in particular in the areas of vascular biology, neurology, cardiology and general medicine. She is specifically interested in the role of the microvasculature as a dynamic-interface between circulating blood- and immune-cells, lymphatics and tissue. Her group studies how circulating cells communicate, adhere and migrate across endothelial borders, along with investigating how circulating and resident cells can render systemic inflammatory responses and alter local inflammatory and thrombotic states.
19.1A: Structure of the Lymphatic System
This article, the first in a six-part series , gives an overview of the lymphatic system, which circulates lymph fluid around the body to drain tissue, transport fat and activate immune responses. This article is the first in a six-part series about the lymphatic system. It discusses how the system is structured and how it functions, focusing on tissue drainage, fat transportation and activation of immune responses. It also examines the causes, symptoms and treatment of oedema. Part 2 will focus on the lymphatic organs, part 3 will examine immunity in more detail, part 4 will discuss allergies, anaphylaxis and anaphylactic shock, part 5 will focus on vaccinations and immunological memory, and part 6 will discuss immunotherapies. Nursing Times [online]; 10, This is the first article in a six-part series examining the lymphatic system and immunity.
The lymphatic system is a network of tissues, vessels and organs that work together to move a colorless, watery fluid called lymph back into your circulatory system your bloodstream. The lymphatic system collects this excess fluid, now called lymph, from tissues in your body and moves it along until it ultimately returns it to your bloodstream. The lymphatic system collects excess fluid that drains from cells and tissue throughout the body and returns it to the bloodstream, which is then recirculated through the body. Some happen during development before birth or during childhood. Others develop as a result of disease or injury.
The lymphatic system is part of the immune system. It also maintains fluid balance and plays a role in absorbing fats and fat-soluble nutrients. The lymphatic or lymph system involves an extensive network of vessels that passes through almost all our tissues to allow for the movement of a fluid called lymph. Lymph circulates through the body in a similar way to blood. There are about lymph nodes in the body.

The lymphatic system , or lymphoid system , is an organ system in vertebrates that is part of the circulatory system and the immune system. It is made up of a large network of lymph, lymphatic vessels , lymph nodes, lymphatic or lymphoid organs, and lymphoid tissues. Unlike the cardiovascular system, the lymphatic system is not a closed system. The human circulatory system processes an average of 20 litres of blood per day through capillary filtration , which removes plasma from the blood. Roughly 17 litres of the filtered plasma is reabsorbed directly into the blood vessels , while the remaining three litres are left in the interstitial fluid.
A number of specialised tissues are important for the proper functioning of the immune system. Among these are the lymph nodes , which provide an ideal environment for communication between immune cells. This environment is necessary for proper activation of the T and B cells or lymphocytes that are required for defence against many pathogens.

Lymphatic system , a subsystem of the circulatory system in the vertebrate body that consists of a complex network of vessels, tissues , and organs. The lymphatic system helps maintain fluid balance in the body by collecting excess fluid and particulate matter from tissues and depositing them in the bloodstream. It also helps defend the body against infection by supplying disease-fighting cells called lymphocytes.
- Что еще мне остается? - Он представил Хейла на скамье подсудимых, вываливающего все, что ему известно о Цифровой крепости. - Весь мой план рухнет. Должен быть какой-то другой выход. - Решайте! - крикнул Хейл и потащил Сьюзан к лестнице. Стратмор его не слушал. Если спасение Сьюзан равнозначно крушению его планов, то так тому и быть: потерять ее значило потерять все, а такую цену он отказывался платить.
То, что она увидела, казалось лишенным всякого смысла. 22: РУЧНОЕ ОТКЛЮЧЕНИЕ ГЛАВА 35 Беккер в шоке смотрел на Росио. - Вы продали кольцо. Девушка кивнула, и рыжие шелковистые волосы скользнули по ее плечам. Беккер молил Бога, чтобы это оказалось неправдой. - Рего… Но… Она пожала плечами и произнесла по-испански: - Девушке возле парка.
Хейл решил выйти подышать воздухом, за что она была ему безмерно благодарна.
