Question: When water is lost, but electrolytes are retained,?

When water is lost in the plasma volume but electrolytes are retained?

Fluid, Electrolyte, and Acid-Base Balance MC Questions

Question Answer
When water is lost but electrolytes are retained, the osmolarity of the ECF rises and osmosis then moves water out of the ICF and into the ECF until isotonicity is reached

Term About two-thirds of the body fluid is within cells and is termed________ fluid Definition Intracellular
Term When water is lost, but electrolytes are retained, osmosis moves water from the ________ to the ________ Definition Intracellular fluid to the Extracellular fluid

When the amount of water you gain each day is equal to the amount you lose to the environment you are in?

Water makes up 99% if the volume of the fluid outside the cell. Essential ingredient to the cytoplasm. Fluid Balance is when the amount of water you gain each day is equal to the amount you lose to the environment.

What happens when the pH of the ECF drops?

The normal range of pH in the ECF is between 7.35 and 7.45. – the nervous and cardiovascular systems are sensitive to fluctuations in pH. – if pH drops, the carboxylate ion and the amino group can act as weak bases and accept additional hydrogen ions, forming a carboxyl group and an amino acid.

What happens when blood becomes more alkaline?

An increase in alkaline causes pH levels to rise. When the levels of acid in your blood are too high, it’s called acidosis. When your blood is too alkaline, it is called alkalosis. Respiratory acidosis and alkalosis are due to a problem with the lungs.

Which hormone stimulates the thirst mechanism?

Thirst isn’t the brain’s only response to dehydration. When the body gets low on water, the hypothalamus increases the synthesis of an antidiuretic hormone called vasopressin, which is secreted by the pituitary gland and travels to the kidneys.

Which is the most abundant cation in the ICF?

Within the extracellular fluid, the major cation is sodium and the major anion is chloride. The major cation in the intracellular fluid is potassium.

In which body fluid do the phosphate and protein buffer systems help regulate the pH?

The buffer systems functioning in blood plasma include plasma proteins, phosphate, and bicarbonate and carbonic acid buffers. The kidneys help control acid-base balance by excreting hydrogen ions and generating bicarbonate that helps maintain blood plasma pH within a normal range.

Which hormone most affects the osmolarity of urine?

Your body has a unique way to control osmolality. When osmolality increases, it triggers your body to make antidiuretic hormone (ADH). This hormone tells your kidneys to keep more water inside your blood vessels and your urine becomes more concentrated. When osmolality decreases, your body doesn’t make as much ADH.

What is the kidney’s response to acidosis?

The renal response to metabolic acidosis is mediated, in part, by increased expression of the genes encoding key enzymes of glutamine catabolism and various ion transporters that contribute to the increased synthesis and excretion of ammonium ions and the net production and release of bicarbonate ions.

How does the body get rid of excess hydrogen?

2. Excretion of Hydrogen Ions (H+) by the Kidneys. When the blood becomes too acidic, t he kidneys remove excess H+ ions from the body and excrete them in the urine. Hydrogen ions are removed by the proximal convoluted tubules (PCTs) and collecting tubules (CTs) that are part of the nephrons of the kidneys.

What happens to the ICF and ECF when water is lost but electrolytes are retained?

When water is lost, but electrolytes are retained osmosis moves water from the ICF to the ECF. NOTE: water loss is from ECF, because water loss is due to urination (plasma water is lost), sweating (interstitial fluid is lost), bleeding (plasma is lost)… 7.

Which represents the largest fluid compartment in the body?

The largest compartment is the intracellular fluid compartment (ICF), which accounts for about two thirds of total body water. The extracellular fluid compartment (ECF) makes up the balance. Extracellular water can further be divided into the intravascular fluid compartment and the interstitial fluid compartment.

Which electrolyte has the greatest influence on water balance in the body?

(See also Overview of Electrolytes.) Most of the body’s sodium is located in blood and in the fluid around cells. Sodium helps the body keep fluids in a normal balance (see About Body Water). Sodium plays a key role in normal nerve and muscle function.

What are the major sources of hydrogen ions in the body?

The major sources of hydrogen ions are from the anaerobic respiration producing lactic acid, aerobic respiration of glucose, metabolism of fat producing ketones, production of carbon dioxide producing bicarbonate.
