Water is added to the body only through the digestive tract.

Osmoreceptors associated with thirst are located in the gastrointestinal tract.

Match each term with its corresponding definition. -Outside the cell

A normal saline solution consists of a 9% solution of NaCl.

Explain how the renin-angiotensin-aldosterone mechanism works to help maintain fluid balance.

Edema may occur when:

Respiration contributes to the obligatory water loss of the body.

The body fluid that stays constant as a percentage of body weight throughout life is:

Osmoreceptors assist in controlling homeostasis of body fluids by:

Organic compounds are important sources of electrolytes.

Which of the following is not a cause of hypervolemia?

A continuous movement of sodium occurs between a number of internal secretions, such as saliva, gastric and intestinal secretions, bile, and pancreatic fluid.

Whereas sodium is the predominant cation in blood plasma, potassium is the predominant cation in intracellular fluid.

The total charge in a solution of dissolved electrolytes and a solution of dissolved non-electrolytes would both be zero.

When compared chemically, intracellular fluid and plasma are almost identical.

The skin is one of the areas of the body that contributes to obligatory water loss.

Angiotensin I is converted to angiotensin II by the liver.

Normal values for total body water as a percentage of body weight will vary from 45% to 75%.

Which of the following body fluid compartments has the same volume (percentage of body weight) in the infant, the adult male, and the adult female?

The release of ADH will cause an increase in the reabsorption of sodium and water by the kidney.
