1 In one study, 56% of men who cheated said they were in very happy marriages; only 34% of women said the same. 2  p. 3  A study by infidelity site Victoria Milan revealed that more than half of wayward women expect the man theyâre cheating with to pay for their nights out. Approximately 68% of men never admit to cheating or do so only after their wives have concrete evidence of the affairs. 2  j. 3  While the Internet has certainly made cheating easier, as far back as 1953, sex researcher Alfred Kinsley learned that about 50% of husbands had had at least one affair by the time they were 40.
The body has a wide array of mechanisms to maintain homeostasis in the blood and extracellular fluid. The most important way that the pH of the blood is kept relatively constant is by buffers dissolved in the blood. Other organs help enhance the homeostatic function of the buffers.
Role of the kidneys. The kidneys are able to affect blood pH by excreting excess acids or bases. The kidneys have some ability to alter the amount of acid or base that is excreted, but because the kidneys make these adjustments more slowly than the lungs do, this compensation generally takes several days.he body's balance between acidity and alkalinity is referred to as acid-base balance. The acidity or alkalinity of any solution, including blood, is indicated on the pH scale. The blood's acid-base balance is precisely controlled because even a minor deviation from the normal range can severely affect many organs.
