What else can I help you with?
True or False The most abundant negative ion in extracellular fluid is calcium?
False. The most abundant negative ion in extracellular fluid is chloride, not calcium. Calcium is usually found as a positively charged ion in extracellular fluid.
Are the principal ions in extracellular fluid sodium and chloride and bicarbonate?
Yes, the principal ions in extracellular fluid are sodium, chloride, and bicarbonate. Sodium and chloride are the major cations and anions, respectively, while bicarbonate helps regulate pH balance in the body.
Why extracellular fluid is known to be the internal environment of body?
Extracellular fluid refers to all the fluids outside of our cells in our bodies. The term for the fluid inside of our cells is intracellular and refers to the cytoplasm. The fluids outside of our cells is referred to as extracellular because they are outside the cells. There are two different categories of extracellular fluids. The first is interstitial fluid which is the fluid that is in between our cells and tissues, and the other is plasma, which is found in our blood. The reason why this is called the internal environment is because this is the environment that our cells in our bodies live in. So the internal environment in our body is really the "sea" of fluids outside our cells that keeps them alive, hence their environment. This is much like the things outside of our bodies that are our environment that keeps us alive.
What are the two main contributors to the buffer capacity of the blood?
The two main contributors to the buffer capacity of blood are bicarbonate ions (HCO3-) and hemoglobin. Bicarbonate ions help regulate pH by acting as a major buffer system in the blood, while hemoglobin can bind to hydrogen ions as a buffer in red blood cells.
What is the most abudant anion in the ECF?
The most abundant anion in the extracellular fluid (ECF) is chloride (Cl-).
How much of the extracellular fluid makes up the blood plasma?
Blood plasma makes up about 20-25% of the extracellular fluid in the body. The other main component of extracellular fluid is interstitial fluid, which makes up the remaining 75-80%.
What is found in extracellular fluid?
The principal elements in the extracellular fluid are sodium, potassium and calcium.
Is the extracellular fluid hydrophilic or hydrophobic?
The extracellular fluid is hydrophilic, meaning it is attracted to water.
Where is the extracellular fluid found in the body?
Extracellular is outside cells and intracellular is inside, so that extracellular fluid would not be inside cells.
What is the most important buffer in extracellular fluids?
The bicarbonate buffer system is the most important buffer in extracellular fluids, including blood. It helps maintain the pH level of the body within a narrow range by regulating the levels of bicarbonate ions and carbonic acid.
Why does metabolic acidosis causes hypochloremia?
More Cl- is being excreted as Nh4Cl to buffer the excess acid in the renal tubules, leaving less Cl- in the Extracellular Fluid
Extracellular fluid would not include?
Cells and intracellular components are not part of the extracellular fluid, as it is found outside of cells within the body. Intracellular fluid would not be considered part of the extracellular fluid.
What is extracellular fluid AND where is it found?
Extracellular fluid is the fluid outside of cells. It is in the interstitial space, in the blood vessels and lymph vessels
Is blood plasma extracellular or intracellular?
It is the intravascular fluid part of extracellular fluid (all body fluid outside of cells)
Is urine from a catheter a intracellular or extracellular fluid?
Urine from a catheter is considered an extracellular fluid because it is produced and stored outside the cells of the body.
Extracellular fluid is found everywhere in the body EXCEPT?
Extracellular is outside cells and intracellular is inside, so that extracellular fluid would not be inside cells.
What are some uses for extracellular fluid?
Extracellular fluid is the body fluid outside the cell that is composed of blood plasma, interstitial fluid, lymph and transcellular fluid. It resides outside the cells and transports mmaterials to and from the cells
