When pure water is consumed the extracellular fluid becomes quizlet?
When large amounts of pure water are consumed: -the ECF becomes hypertonic to the ICF. -the volume of the ECF will decrease. -osmolarities of the two compartments will be slightly lower.
What happens to the ECF and ICF when pure water is consumed?
When pure water is consumed, a. the ECF becomes hypertonic to the ICF.
Which of the following occurs when large amounts of pure water are consumed?
Fluid, Electrolyte, and Acid-Base Balance MC Questions

When large amounts of water are consumed?
Excess water in the body causes the body's salt levels to go down and the cells to swell. This swelling causes them to grow in size, and those in the brain press against the skull. This pressure causes a throbbing headache and may lead to brain impairment and trouble breathing.
What will happen if the extracellular fluid ECF becomes hypotonic with respect to the intracellular fluid ICF )?
If ECF becomes more dilute (hypotonic) with respect to ICF… water will move from the ECF into the cells, & the volume of the ICF will increase accordingly.

What is the difference between ICF and ECF?
The intracellular fluid (ICF) compartment is the system that includes all fluid enclosed in cells by their plasma membranes. Extracellular fluid (ECF) surrounds all cells in the body.
What is interstitial fluid and extracellular fluid?
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.
Does dehydration cause alkalosis or acidosis?
There are two kinds of metabolic alkalosis: Chloride-responsive alkalosis results from loss of hydrogen ions, usually by vomiting or dehydration. Chloride-resistant alkalosis results when your body retains too many bicarbonate (alkaline) ions, or when there's a shift of hydrogen ions from your blood to your cells.
Which can cause hypotonic hydration?
Hypotonic dehydration is mostly caused by diuretics, which cause more sodium loss than water loss. Hypotonic dehydration is characterized by low sodium and osmolality.
What is overhydration called?
Hyponatremia is the medical term for a sodium imbalance in the body. A sodium imbalance can occur when excessive amounts of water are consumed, flooding the cells. It is sometimes also called water intoxication, overhydration, or water poisoning.
What is drinking too much water called?
Overhydration is an excess of water in the body. People can develop overhydration if they have a disorder that decreases the body's ability to excrete water or increases the body's tendency to retain water. Drinking too much water rarely causes overhydration because normal kidneys easily excrete excess water.
What happens to intracellular fluid during dehydration?
In dehydration, fluid from the extracellular compartment is depleted first, followed by fluid from the intracellular space. Fluid loss from the intracellular space results in cellular shrinkage and metabolic dysfunction. Dehydration occurs because of decreased water intake, increased fluid loss, or both.
What stimulates sodium ion retention?
Aldosterone causes the kidneys to retain sodium and to excrete potassium. When sodium is retained, less urine is produced, eventually causing blood volume to increase. The pituitary gland secretes vasopressin (sometimes called antidiuretic hormone).
When water is lost by electrolytes are retained quizlet?
increase the osmolarity of the blood. metabolic alkalosis. When water is lost, but electrolytes are retained, osmosis moves water from the ICF to the ECF.
What is intracellular and extracellular water?
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 difference between plasma and interstitial fluid?
The main difference between plasma and interstitial fluid is that plasma contains more proteins whereas interstitial fluid contains fewer proteins. Most of the other dissolved products such as nutrients and electrolytes occur in similar concentrations in both plasma and interstitial fluid.
Is urine a body fluid?
Urine is a liquid byproduct of the body secreted by the kidneys through a process called urination and excreted through the urethra.
What is cell fluid called?
The fluid inside the cell is called intracellular fluid (ICF). All the fluid outside of the cell is called extracellular fluid (ECF) and is separated from the intracellular fluid by a semipermeable membrane that surrounds the cell.
What is meant by acidosis?
Acidosis is a condition in which there is too much acid in the body fluids. It is the opposite of alkalosis (a condition in which there is too much base in the body fluids).
What is alkalosis?
Alkalosis is a condition in which the body fluids have excess base (alkali). This is the opposite of excess acid (acidosis).
Is dehydration hypertonic or hypotonic?
There are three main types of dehydration: hypotonic (primarily a loss of electrolytes), hypertonic (primarily loss of water), and isotonic (equal loss of water and electrolytes). The most commonly seen in humans is isotonic.
What is isotonic dehydration?
Isotonic dehydration is loss of water with preserved normal effective osmolality of body fluids. Causes include loss of isotonic fluids via the gastrointestinal tract, kidneys, or skin (burns); loss of blood; or as a result of fluid sequestration in the “third space” (eg, the peritoneum).
What happens if drink too much water?
When you drink too much water, your kidneys can't get rid of the excess water. The sodium content of your blood becomes diluted. This is called hyponatremia and it can be life-threatening.
Is it harmful to drink too much water?
However, drinking too much water can also be dangerous. Overhydration can lead to water intoxication. This occurs when the amount of salt and other electrolytes in your body become too diluted. Hyponatremia is a condition in which sodium (salt) levels become dangerously low.
What happens if you drink pee?
By drinking urine, you are consuming these toxins that your body explicitly intended to remove. This can lead to kidney damage or disease as these organs need to work harder to handle the increased concentration of toxic substances.
Why do I pee so much when I drink water?
When you drink more, you'll pee more. Your body is more than 60% water, so if you're drinking the correct amount of water for your size, you'll be drinking a lot of water.
What causes hypotonic?
Hypotonic dehydration occurs when sodium loss is greater than water loss, resulting in a decrease in serum osmolality. This causes a shift of water from the extracellular space into the intracellular space. The cells swell and cerebral edema may occur. Hyponatremia can be acute or chronic.

Where is salt stored in the body?
First, a larger sodium mass is stored in the extracellular fluid, and this compartment expands in most kidney patients. Second, an increased amount of sodium is stored in the skin and muscles.
