Water Balance Worksheet
Water Balance
Adipose tissue is one of the most hydrated of all tissues in the human body. False
The most abundant cation in intracellular fluid is sodium. False
Electrolytes determine most of the chemical and physical reactions of the body. True
Solutes, regardless of size, are able to move freely between compartments because water carries them along the osmotic gradients.False
The thirst center in the brain is located in the hypothalamus.True
Dehydration can be caused by endocrine disturbances such as diabetes mellitus or diabetes insipidus.True
It is impossible to overhydrate because people need as much water as they can drink to carry out ordinary body functions. False
Water imbalance, in which output exceeds intake, causing an imbalance in body fluids, is termed dehydration. True …show more content…
True
Weak acids are able to act as chemical buffering systems for the body because they partially dissociate.TrueThe phosphate buffer system is relatively unimportant for buffering blood plasma. True
The single most important blood buffer system is the bicarbonate buffer system. True
One of the most powerful and plentiful sources of buffers is the protein buffer system.True
As ventilation increases and more carbon dioxide is removed from the blood, the hydrogen ion concentration of the blood decreases. True
Regulation of the acid-base system is accomplished mainly through respiratory control, and the kidneys also play a small role. False
Severe damage to the respiratory system rarely will result in acid-base imbalances. False
Respiratory acidosis results when lungs are obstructed and gas exchange is inefficient. True
Prolonged hyperventilation can cause alkalosis. True
Thirst is always a reliable indicator of body water need. False
Blood acidity results in depression of the CNS, whereas blood alkalosis results in overexcitement of the CNS.
