Five pairs of syllables, each pair being an unstressed syllable followed by a stressed one. In iambic pentameter there are ten syllables per line. The first syllable of the line is unstressed, followed by the second syllable which is stressed, and so on until you reach the tenth syllable.
If the body's pH balance is too low (acidic), the lungs and the kidneys constantly remove carbon dioxide, which helps to neutralize hydrogen ions. Conversely, if it is too high (alkaline), the kidneys excrete bicarbonate iron that elevates the hydrogen ion concentration, creating a more acidic environment.n chemistry, pH is the acronym for Potential Hydrogen and it is the measurement of acidity. An acid is any chemical that releases hydrogen ions in solution. The Potential Hydrogen scale was invented in 1909 to measure the acidity of beer.
The lungs and kidneys are the major organs involved in regulating blood pH. 1  The lungs flush acid out of the body by exhaling CO2. 2  The kidneys excrete acids in the urine, and they regulate the concentration of bicarbonate (HCO3-, a base) in blood.
