Question
The chemoreceptor reflexesMultiple Choicecause a decrease in blood flow to the lungs.cause a decrease in blood flow to the heart.helps decrease blood oxygen levels.cause an increase in blood flow to the lungs.Both "cause a decrease in blood flow to the lungs." and "cause a decrease in blood flow to the heart." are correct.
Solution
The chemoreceptor reflexes cause an increase in blood flow to the lungs. This is because chemoreceptors in the body detect changes in the levels of oxygen, carbon dioxide, and pH in the blood. When oxygen levels are low, or carbon dioxide levels or pH are high, these receptors send signals to the brain. The brain then sends signals to the heart to increase the heart rate and to the blood vessels to dilate, increasing blood flow to the lungs. This allows more oxygen to be taken in and more carbon dioxide to be expelled, helping to restore the balance of these substances in the blood.
