most of the carbon dioxide produced by the body is transported to the lungs in
carbonic acid
potassium carbonate ions
blood plasma
bicarbonate ions
a gaseous form

Explanation:

1. Most carbon - dioxide in the blood is transported as bicarbonate ions in the plasma. This is due to a series of chemical reactions in the red blood cells and plasma.
2. Inhaled air is warmed, humidified, and filtered by the nasal mucosa, not cooled.
3. Most of the carbon - dioxide produced by the body is transported to the lungs as bicarbonate ions. Carbon dioxide diffuses into red blood cells, reacts with water to form carbonic acid which dissociates into bicarbonate and hydrogen ions. Bicarbonate ions then diffuse into the plasma for transport.

Answer:

Question 1: True
Question 6: False
Question 7: bicarbonate ions
