What is intracellular and extracellular?
The intracellular fluid is the fluid contained within cells. The extracellular fluid—the fluid outside the cells—is divided into that found within the blood and that found outside the blood; the latter fluid is known as the interstitial fluid.
What is the intravascular compartment?
The intravascular compartment contains fluid (i.e., blood) within the cardiac chambers and vascular system of the body. When the fluid volume within the interstitial compartment (space between the cells and blood vessels) increases, this compartment increases in size leading to tissue swelling (i.e., edema).
What cytosol means?
: the fluid portion of the cytoplasm exclusive of organelles and membranes. — called also ground substance.
What is the fluid matrix inside the cell is called?
The fluid portion of the cytoplasm is called the cytosol. It is the liquid matrix that surrounds the organelles inside the cell. The cytosol is sometimes referred to as the cytoplasmic matrix, cytomatrix, or cell matrix.
What is the largest fluid compartment in the body?
intracellular fluid
As shown in Figure 1-1, the largest volume of fluid in the body is inside cells. The intracellular fluid (ICF) compartment comprises approximately 40% of body weight (approximately two thirds of total body water). The composition of ICF is very different from extracellular fluid (ECF) (Fig. 1-2).
What is the other name of cytosol?
The cytosol, also known as cytoplasmic matrix or groundplasm, is one of the liquids found inside cells (intracellular fluid (ICF)).
What is the role of cytosol?
The cytosol serves several functions within a cell. It is involved in signal transduction between the cell membrane and the nucleus and organelles. It transports metabolites from their production site to other parts of the cell. It is important for cytokinesis, when the cell divides in mitosis.
What is fluid matrix?
Blood is both a tissue and a fluid. It is a tissue because it is a collection of similarly specialized cells that serve particular functions. These cells are suspended in a liquid matrix which is called plasma, hence, the fluid matrix of blood is called plasma.
How are dissolved substances in a fluid distributed in the body?
Any dissolved substances in a fluid. refers to all dissolved substances in a fluid, which may be charged, such as sodium (Na + ), or uncharged, such as glucose. In the human body, water and solutes are distributed into two compartments: inside cells, called intracellular, and outside cells, called extracellular.
What do you call a mixture of oil and water?
A mixture of oil and water is called an emulsion. An emulsion is defined as a mixture of two liquids that normally do not combine. When the liquids are shaken or stirred, a temporary emulsion occurs; however, after a short period of time, the liquids separate into individual layers.
Which is the fluid found in the cells?
The intracellular fluid of the cytosol or intracellular fluid (or cytoplasmic matrix) is the liquid found inside cells. The cytosol is a complex mixture of substances that include proteins, ions, and organelles dissolved in water.
What kind of substance is dissolved in water?
Substances that when dissolved in water disassociate into charged ions. are substances that, when dissolved in water, disassociate into charged ions. Positively charged electrolytes are called cations and negatively charged electrolytes are called anions.
The intracellular fluid of the cytosol or intracellular fluid (or cytoplasmic matrix) is the liquid found inside cells. The cytosol is a complex mixture of substances that include proteins, ions, and organelles dissolved in water.
What makes up the fluid in the cytosol?
The cytosol is a complex mixture of substances that include proteins, ions, and organelles dissolved in water. Extracellular fluid (ECF) or extracellular fluid volume (ECFV) usually denotes all body fluid outside of cells, and consists of plasma, interstitial, and transcellular fluid.
How does the exchange of substances take place in extracellular fluid?
The extracellular fluid provides the medium for the exchange of substances between the ECF and the cells, and this can take place through dissolving, mixing and transporting in the fluid medium. Substances in the ECF include dissolved gases, nutrients, and electrolytes, all needed to maintain life.
What kind of electrolytes are dissolved in water?
Electrolytes are substances that, when dissolved in water, dissociate into charged ions. Positively charged electrolytes are called cations and negatively charged electrolytes are called anions. For example, in water sodium chloride (the chemical name for table salt) dissociates into sodium cations (Na+) and chloride anions (Cl−).
