Fixed acids are generally regulated by physiological buffering provided by the: kidneys 38. The hormone ANP: increases urine output and decreases blood volume. Angiotensin II, aldosterone, and ADH each help decrease urine output. When compared with the effects of blood pressure and osmolarity on fluid intake, the effects of saliva and stomach distention are more immediate but less accurate 35. Which of the following does not turn off the thirst center of the brain? Decreased salivary secretions 34. Researchers have inflated balloons inside the stomachs of experimental subjects and have found that distention of the stomach causes thirst to: decrease 33. The thirst center of the brain is located in the: hypothalamus 32. ON 30.įluid intake causes blood volume to increase. Decreases in blood pressure turn the thirst center of the brain. Feelings of thirstiness are brought on by: decreases in salivary secretions and increases in blood smolarity. Edema is an example of: fluid sequestration Blockage 0T lympnatlc vessels or surgical removal 0T lympnatlc vessels Increases the likelihood of: edema, which is a an example of fluid sequestration 28. If a runner drinks too much water before a marathon, they run a risk of water intoxication, also known as: hypotonic hydration 25.Extreme hypotonic hydration can cause brain cells to swell.Ģ6. Diabetes mellitus, profuse sweating, and hyposecretion of ADH can each lead to: dehydration 24. Renal failure would likely lead to: volume excess 23. If someone in an accident suffered severe burns as well as hemorrhage, they would be at high risk for: volume depletion. Facultative water loss is loss that: is controlled by hormone effects on the kidney 20.In the condition of volume excess, fluid gain involves: no change in the osmolarity of body fluid. Water lost through feces is considered water loss. Which type of intake accounts for most of our daily fluid intake? Preformed water 18. When fluid intake equals fluid output, and there is a normal distribution of solvent and solutes in the body’s fluid compartments, fluid exists.
As an individual becomes dehydrated, the net movement of fluid in their body is from cells toward plasma. If someone runs a marathon through a desert while eating pretzels and not drinking water, their plasma osmolarity: rises and becomes hypertonic to the interstitial and intracellular fluid compartments. Drinking a liter of water will cause the osmolarity of blood plasma to: decreases 14. Which statement accurately describes the permeability to water of the cell membrane and the capillary wall? Both the plasma membrane and the capillary wall are permeable to water. Interstitial fluid has a relatively concentration of sodium and chloride the concentrations of ions within the interstitial fluid and blood plasma are very High/different 12. * All Partners were chosen among 50+ writing services by our Customer Satisfaction Team Interstitial fluid of the body’s extracellular fluid. The plasma of our blood constitutes than half of the fluid in our body plasma is part of the composes about fluid. Most of the fluid in our body is contained within our cells. A comparison of the two major body fluid compartments reveals that: two-thirds of the total fluid is within our cells and one- third is outside our cells. Elderly individuals percentage of body fluid and are therefore rone to fluid imbalances.
Fluid imbalances are more common in individuals with a generally have a percentage of body fluid. When comparing a lean adult female to a lean adult male, which will most likely have a higher percentage of body fluid? The Male 5. When comparing two individuals of the same body weight, the one with more muscle and less fat will have a higher percentage of fluid in their body. In elderly individuals, 75% of body weight is made up of fluid. At which stage of life is the percentage of fluid in the human body highest? Infancy 2.
