How does the hemoglobin-oxyhemoglobin buffer system help maintain the pH of body fluids?
Hemoglobin oxyhemoglobin is one of the main sources of extracellular fluids for the pH of body fluids. It helps with the protein of the body. It is needed for pH levels.
Are the principal ions in extracellular fluid sodium and chloride and bicarbonate?
YES!
True or False The most abundant negative ion in extracellular fluid is calcium?
False. It's Chloride
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 sort of Ca2 concentrations are maintained by the calcium pump?
The Ca2+ concentration is higher in the extracellular fluid than in the cytoplasm.
Why and how does the ECF differ from the ICF?
The acronym ECF stands for extracellular fluid. Extracellular fluid is the fluid outside of the cell in the human body.
What is the most important buffer in extracellular fluids?
Bicarbonate Buffer System (only important ECF buffer)
Is plasma intracellular or extracellular?
Chloride is an Anion in Extracellular Fluid
What is found in extracellular fluid?
The principal elements in the extracellular fluid are sodium, potassium and calcium.
Is urine from a catheter a intracellular or extracellular fluid?
Extracellular.
The main hormone that acts on the kidneys to regulate sodium ion concentration of the extracellular fluid is?
Aldosterone
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.
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
Fluid found OUtSiDE of a cell is called?
cytoplasm
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
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.
Is blood plasma extracellular or intracellular?
It is the intravascular fluid part of extracellular fluid (all body fluid outside of cells)
