An understanding of the physiology of body fluids is essential when considering appropriate fluid resuscitation and fluid replacement therapy in critically-ill patients. In healthy humans, the body is composed of approximately 60% water, distributed between intracellular and an extracellular compartments The intracellular fluid is the fluid within the cells of the body. The remaining one-third of body water is outside cells, in the extracellular fluid compartment (ECF). The ECF is the body's internal environment and the cells external environment. Exchange of gases, nutrients, water, and wastes between the three fluid compartments of the body
The water in the body is contained within the numerous organs and tissues of the body. These innumerable fluids can be lumped together into larger collections which can be discussed in a physiologically meaningful way. These collections are referred to as compartments b)Abouttwo thirds of total body water is intracellular. c)Mostextracellular water is intravascular. d)Intracellularfluid is about 12 liters. e)Interstitialfluid volume is 5% of total body water .

Body fluid homeostasis is directed at achieving stability in the osmolality of body fluids and the volume of plasma. Such homeostatic regulation is promoted by several mechanisms intrinsic to the physiology of body fluids and the cardiovascular system Body fluids are considered to be the interstitial fluids, saliva, tears, and gastric juices. They moisten the tissues, muscles, body organs and skin. In Chinese medicine, the production of these fluids is influenced by proper gastrointestinal function by the spleen and stomach qi
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 the body fluids by excreting osmotically dilute or concentrated urine. 2. They regulate the concentrations of numerous ions in blood plasma, including Na +, K , Ca 2+, Mg , Cl−, bicarbonate (HCO 3−), phosphate, and sulfate. 3. They play an essential role in acid-base balance by excreting H+ when there is excess acid or HCO 3 − when there is excess base. 4 • Approximately 30% of the body's fluid is interstitial. • Approximately 8% of the body's fluid is blood plasma. Page 11. Composition of Body Fluids • Label the components on this diagram as follows: nonelectrolytes, electrolytes, solvent, colloid, suspended particle: • You are looking at plasma, a typical body fluid Body fluids, bodily fluids, or biofluids are liquids within the human body. In lean healthy adult men, the total body water is about 60% (60-67%) of the total body weight; it is usually slightly lower in women (52-55%). The exact percentage of fluid relative to body weight is inversely proportional to the percentage of body fat
BODY FLUID COMPARTMENTS | GENERAL PHYSIOLOGY- Intracellular fluid- Extracellular fluid (plasma & Interstitial fluid)- Body fluid defici body fluid. 1. Any fluid in the body including blood, urine, saliva, sputum, tears, semen, milk, or vaginal secretions. 2. BF is often used with specific reference to those fluids to which health care workers might reasonably be exposed including blood, urine, saliva, and semen Total body water in an average human being, weighing about 70 kg is 40 litres to 45 litres. In human being it is about 65% of the body weight in males and about 10% less in females. But the above values vary mostly with the relative degrees of leanness and fatness of the individual. In lean person, the value is higher than that of in obese person Mechanisms which maintain intracellular fluid tonicity. Mechanisms which maintain extracellular fluid volume. Vasopressin as a regulator of tonicity and body water volume. Physiological response to dehydration: the loss of 1L of body water. Response to haemorrhage: the loss of 1L of blood Two thirds of the body fluids is intracellular fluid,and the rest is extracellular fluid.Also in the extracellular fluid 80% is the interstitial fluid and the remaining 20% is the plasma. The amount of the fluids in the compartments may vary due to the movement of fluids from one compartment to another due to the difference in concentrations.
Physiology of the blood and body fluids Fig. 2.1 Body composition and fluid components. In Figure 2.3, osmotic pressure exerted by the solution forces water to move from left to right, as hydrostatic pressure forces movement in the opposite direction Proteins and related substances (18%) Minerals (7%) Fat (15%) Water (60%) 15% interstitial fluid Body Fluid Compartments - Part 2 In order to have a solid understanding of physiological principles, it is essential that one understand the organization of body fluid compartments, as well as the composition of the fluids in these compartments. Test your understanding of body fluid compartments by taking this simple quiz 2.2.2 Total Body Water. This is estimated by measuring the volume of distribution of isotopes of water. Tritium oxide (THO) is used because it is a weak beta emitter making it easy to measure in a liquid scintillation counter. Rapid mixing of tritiated water throughout all compartments occurs during a 3 to 4 hour equilibration period The physiological functions of body fluid include the following three aspects. Moistening and Nourishing. Body fluid contains large quantity of water and nutrient substances to moisten and nourish the viscera and the body. To be specific, the thin fluid, distributed in the skin and orifices, mainly functions to moisten the body; the thick fluid. Physiology of Body Fluid Compartments and Body Fluid Movements. (IVS, plasma), interstitial space (ISS), and transcellular space (TCS) (Fig. 1.1). These compartments contain the body water and are surrounded by a semi-permeable membrane through which fluids pass from one space to another and which separates them

Figure 26.1. 2: Fluid Compartments in the Human Body. The intracellular fluid (ICF) is the fluid within cells. The interstitial fluid (IF) is part of the extracellular fluid (ECF) between the cells. Blood plasma is the second part of the ECF. Materials travel between cells and the plasma in capillaries through the IF Total body water can be subdivided into two major compartments, intracellular fluid which is fluid inside cells, and extracellular fluid which is fluid outside of cell like in the blood and in the interstitial tissue between cells. Assuming that the total body water is about 60% of their body weight, roughly 2/3 of that, or 40% is intracellular.
PHYSIOLOGICAL VARIATION OF BODY FLUID VOLUME Most of the variation in body fluid between individuals is as a result of variation in amount of body fat or adipose tissue (fat is only about 10% water) Infant: 73-80% Male adult: 60% Female adult: 40-50% Effects of obesity Old age 45 FLUID AND ELECTROLYTE BALANCE PHYSIOLOGY Introduction: Cell function depends not only on a continuous supply of nutrients and removal of metabolic wastes, but also on the physical and chemical homeostasis of the surrounding fluids. Body Fluids Body water content In a healthy young adult, water probably accounts for about half body weight (mass) The ECF contains roughly one-third of the total body water or about 20% of total body weight. The ECF is sub-divided into two other fluid compartments known as the Interstitial Fluid and the Plasma. These compartments are separated by the vasculature. The Interstitial Fluid refers to the total volume of ECF outside of the blood vessels and is.
Osmolality is the preferred expression of physiologists because it is independent of temperature and pressure. The osmolality of plasma = 290 mosmol/kg H 2 O. Body Water Compartments. Water makes up 50-70% of body mass - approximately 42L in a 70kg person. There are two main fluid compartments The kidneys can adjust the concentration of the urine to reflect the body's water needs, conserving water if the body is dehydrated or making urine more dilute to expel excess water when necessary. ADH is a hormone that helps the body to retain water by increasing water reabsorption by the kidneys The human body and even its individual body fluids may be conceptually divided into various fluid compartments, which, although not literally anatomic compartments, do represent a real division in terms of how portions of the body's water, solutes, and suspended elements are segregated. The two main fluid compartments are the intracellular and extracellular compartments Examination of the cerebrospinal fluid (CSF) may provide critically important diagnostic information in a number of infectious and noninfectious medical conditions. Knowledge of the normal physiology and pathophysiology of CSF production and flow is useful in interpreting such test results. This topic will review the normal physiology and. Total body water: • Water comprises 50-70% of total body weight; the rest comprises solids. • Precise volume largely depends on proportion of muscle tissue (which have more water) to adipose tissue (which has less). • Body water is distributed between two major compartments: - Intracellular compartment = 2/3; this is the water contained within cells, and bound by cell membranes
Body Fluids and pH Levels. Saliva, blood and spinal fluid all have a pH of about 7.4. This near neutral level prevents tissue damage that may be caused by levels at either end of the pH scale. Proton pumps that regulate the hydrogen ions in the stomach keep the pH between 1.5 and 3.5 Fluid, in physiology, a water-based liquid that contains the ions and cells essential to body functions and transports the solutes and products of metabolism..
