Anatomy & Physiology

Answer the following statements true (T) or false (F)

1. The carbon dioxide that is exhaled reduces the amount of carbonic acid in the blood. 2. A decreased breathing rate reduces the amount of carbonic acid removed and causes a rise in the pH of the blood. 3. A decrease in breathing rate reduces the amount of carbonic acid removed and causes an increase of hydrogen ions in the blood. 4. Hyperventilation can cause acidosis. 5. Hyperventilation would remove more carbonic acid than normal and would cause a decrease in the hydrogen ion concentration.
