Question

Quizplus · Accepted Answer

An increase in breathing rate is associated with all the given options. When the body needs more oxygen, the breathing rate is increased which results in faster delivery of oxygen by the cardiovascular system (option A). This leads to an increase in cellular respiration in the tissues (option D) because there is more oxygen available for cellular processes. As cellular respiration increases, CO2 production also increases. This CO2 combines with water in the blood to form carbonic acid, which decreases blood pH (option B). Therefore, an increase in breathing rate is the body's response to maintain a balanced pH level.
