The chemical reactions of life take place in aqueous solutions. The dissolved substances in a solution are called solutes. In the human body, solutes vary in different parts of the body, but may include proteins—including those that transport lipids, carbohydrates, and, very importantly, electrolytes. Often in medicine, an electrolyte is referred to as a mineral dissociated from a salt that carries an electrical charge an ion.

25.2B: Fluid Compartments

The major body-fluid compartments includ: intracellular fluid and extracellular fluid plasma, interstitial fluid, and transcellular fluid. The fluids of the various tissues of the human body are divided into fluid compartments. Fluid compartments are generally used to compare the position and characteristics of fluid in relation to the fluid within other compartments. While fluid compartments may share some characteristics with the divisions defined by the anatomical compartments of the body, these terms are not one in the same. The intracellular fluid of the cytosol or intracellular fluid or cytoplasm is the fluid found inside cells. It is separated into compartments by membranes that encircle the various organelles of the cell. For example, the mitochondrial matrix separates the mitochondrion into compartments.

Extracellular fluid ECF denotes all body fluid outside the cells of any multicellular organism. Extracellular fluid is the internal environment of all multicellular animals , and in those animals with a blood circulatory system , a proportion of this fluid is blood plasma. Lymph makes up a small percentage of the interstitial fluid. The ECF can also be seen as having two components — plasma and lymph as a delivery system, and interstitial fluid for water and solute exchange with the cells. The extracellular fluid, in particular the interstitial fluid, constitutes the body's internal environment that bathes all of the cells in the body. The ECF composition is therefore crucial for their normal functions, and is maintained by a number of homeostatic mechanisms involving negative feedback.

Extracellular fluid

Some of the most common and important problems in clinical medicine arise because of abnormalities in the control systems that maintain this constancy of the body fluids. In this chapter and in the following chapters on the kidneys, we discuss the overall regulation of body fluid volume, constituents of the extracellular fluid, acid-base balance, and control of fluid exchange between extracellular and intracellular compartments. The relative constancy of the body fluids is remarkable because there is continuous exchange of fluid and solutes with the external environment, as well as within the different compartments of the body. For example, there is a highly variable fluid intake that must be carefully matched by equal output of water from the body to prevent body fluid volumes from increasing or decreasing. Intake of water, however, is highly variable among different people and even within the same person on different days, depending on climate, habits, and level of physical activity. Some of the water losses cannot be precisely regulated.

Blood , fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. Technically, blood is a transport liquid pumped by the heart or an equivalent structure to all parts of the body, after which it is returned to the heart to repeat the process. Blood is both a tissue and a fluid. It is a tissue because it is a collection of similar specialized cells that serve particular functions. These cells are suspended in a liquid matrix plasma , which makes the blood a fluid. If blood flow ceases, death will occur within minutes because of the effects of an unfavourable environment on highly susceptible cells. The constancy of the composition of the blood is made possible by the circulation , which conveys blood through the organs that regulate the concentrations of its components.

A significant percentage of the human body is water, which includes intracellular and extracellular fluids. In physiology, body water is the water content of the human body. It makes up a significant percentage of the total composition of a body. Water is a necessary component to support life for many reasons. All cells in the human body are made mostly of water content in their cytoplasm.

Других слов для него у нее не. Стратмор оторвался от перил и переложил пистолет в правую руку. Не произнеся ни слова, он шагнул в темноту, Сьюзан изо всех сил держалась за его плечо.

25.2C: Body Fluid Composition

 Рог aqui, senor.  - Он проводил Беккера в фойе, показал, где находится консьерж, и поспешил исчезнуть. Фойе оказалось помещением с изысканной отделкой и элегантной обстановкой. Испанский Золотой век давным-давно миновал, но какое-то время в середине 1600-х годов этот небольшой народ был властелином мира. Комната служила гордым напоминанием о тех временах: доспехи, гравюры на военные сюжеты и золотые слитки из Нового Света за стеклом. За конторкой с надписью КОНСЬЕРЖ сидел вежливый подтянутый мужчина, улыбающийся так приветливо, словно всю жизнь ждал минуты, когда сможет оказать любезность посетителю.

 - Он провел рукой по своим коротко стриженным волосам.  - Я кое о чем тебе не рассказал. Иной раз человек в моем положении… - Он замялся, словно принимая трудное решение.

Значит, приснилось, подумала Сьюзан и села в кровати. Комната в викторианском стиле, сплошь кружева и антиквариат - лучший гостиничный номер в Стоун-Мэнор. Сумка, с которой она приехала, на дощатом полу посреди комнаты… ее белье на спинке стула эпохи королевы Анны, стоящего возле кровати. Вернулся ли Дэвид. Она помнила его тело, прижавшееся к ее телу, его нежные поцелуи. Неужели все это был сон.
