Norepinephrine is a hormone and neurotransmitter that increases blood pressure, heart rate, and breathing rate. It also helps to regulate attention, memory, and learning.
Respiration is the process of breathing, which involves inhaling oxygen and exhaling carbon dioxide. Norepinephrine does not directly increase respiration. However, it can indirectly increase respiration by increasing heart rate and blood pressure. This can lead to an increase in the amount of oxygen that is delivered to the lungs, which can then increase the rate of respiration.
Urine production is the process of forming and excreting urine. Norepinephrine does not directly increase urine production. However, it can indirectly increase urine production by increasing blood pressure. This can lead to an increase in the amount of fluid that is filtered by the kidneys, which can then increase the amount of urine that is produced.
Saliva production is the process of producing saliva. Norepinephrine does not directly increase saliva production. However, it can indirectly increase saliva production by increasing heart rate and blood pressure. This can lead to an increase in the amount of blood that is flowing to the salivary glands, which can then increase the amount of saliva that is produced.
In conclusion, the correct answer to the question “Norepinephrine increases” is D. blood pressure.
