which of the following occurs when an individual loses body water? plasma volume decreases, and electrolyte concentrations rise. plasma volume increases, and electrolyte concentrations decrease. plasma volume deceases, and electrolyte concentrations decrease. plasma volume increases, and electrolyte concentrations increase.

plasma volume decreases, and electrolyte concentrations rise.

which component makes up the largest portion of solid components in the body? carbohydrates minerals proteins lipids

proteins

which of the following accurately lists the solid components of the human body by wright from greatest to smallest? proteins>lipids>minerals>carbohydrates minerals>carbohydrates>proteins>lipids proteins>minerals>lipids>carbohydrates carbohydrates>minerals>lipids>proteins

proteins>lipids>minerals>carbohydrates

extracellular fluids in the body consist of all of the following except aqueous humor cytosol lymph cerebrospinal fluid

cytosol

When water losses outpace water gains, __________ occurs. overhydration. dehydration. hyponatremia. water intoxication.

dehydration

water, by far, is the biggest component of our body fluids. What is the second-largest component of our body fluids? glucose proteins lipids electrolytes

electrolytes

When the amount of water you gain each day is equal to the amount you lose to the environment, you are in acid-base balance dynamic equilibrium electrolyte balance fluid balance

fluid balance

why is there difference in the ICF percentages in males versus females? greater water content of muscle tissues versus adipose tissue. lower intracellular water content of muscle. greater intracellular water content of fats. greater adipose tissue proportion in males versus females.

greater water content of muscle tissues versus adipose tissue.

the body content of water will rise ________ intake is less than outflow. losses exceed gains. outflow exceeds intake. intake exceeds outflow.

intake exceeds outflow

which of the following is NOT an ECF? lymph cerebrospinal fluid intracellular fluid plasma

intracellular fluid

Homeostasis maintains a stable environment, composed of our body fluids. Which of the following is NOT one of the processes for stabilizing body fluid volumes? nutrient balance acid-base balance electrolyte balance fluid balance

nutrient balance

which of the following is NOT a source of water gains? sensible perspiration liquid food metabolism

sensible perspiration

Which of the following is a cause of a fluid shift? Excessive sweating All of the listed choices are causes of a fluid shift Diarrhea Drinking a large volume of water

all of the listed choices are causes of a fluid shift

which of the following is a basic principle in understanding fluid and electrolyte balance? multiple receptors throughout the body directly monitor fluid or electrolyte levels. all homeostatic mechanisms that respond and adjust the composition of body fluids respond to changes in ICF, not in the ECF. cells move water by active transport. the body's content of water or electrolytes will increase if dietary gains exceed losses to the environment.

the body's content of water or electrolytes will increase if dietary gains exceed losses to the environment.

what would be the effect on the osmotic concentration of blood plasma if you were in the desert without water for a day? the osmotic concentration of your plasma would stay the same because of water moving from your cells. the osmotic concentration would decrease because of electrolyte loss in sweat. the osmotic concentration would stay the same because of water and electrolyte loss in sweat at the same rate. the osmotic concentration of your plasma would increase because of water leaving your body.

the osmotic concentration of your plasma would increase because of water leaving your body.

Which of the following represents the largest of water lost each day under normal physiological conditions? feces urine evaporation through the lungs evaporation through the skin

urine

what is meant by the term metabolic water? water obtained from your diet. water generated during oxidative phosphorylation. water produced during anabolic reactions. water produced during the breakdown of glucose by glycolysis.

water generated during oxidative phosphorylation.

which of the following is accurate regarding water content? water makes up about 60 percent of the total body weight of an adult male. men and women contain essentially the same percent body water. adipose tissue is composed of approximately 75 percent water. skeletal muscle tissue is compromised of approximately 10 percent water.

water makes up about 60 percent of the total body weight of an adult male.

Which of the following is NOT a basic principle for understanding fluid and electrolyte balance? Water moves into and out of cells by active transport. Homeostatic mechanisms respond to changes in the ECF. No receptors exist for fluid and electrolyte balance. Water and electrolyte content in the body is a balance between intake and losses.

water moves into and out of cells by active transport.
