Describe the conditions in the blood that cause the medulla oblongata to increase the contraction rate of the diaphragm.
Homework Answers
• The medulla oblongata is the primary respiratory control
center. Its main function is to send signals to the muscles that
control respiration.
• Increased CO2 concentration of blood causes low pH of
blood.
• The respiratory centers contain chemoreceptors that detect pH
levels in the blood.
• In response to a decrease in blood pH, the chemoreceptors sends
signal to the respiratory centre. Then respiratory center (in the
medulla ) sends nervous impulses to the external intercostal
muscles and the diaphragm, to increase the breathing rate and the
volume of the lungs during inhalation.
For one line answer :-
Decreased pH of blood causes the medulla oblongata to increase the
contraction rate of the diaphragm.

Control of the heart rate and force of contraction are controlled by the [ Select] nervous system, where the [ Select] nervous system, through influence of epinephrine and norepinephrine from the adrenal medulla, increases the heart rate, while the [Select] nervous system, through the vagus nerve, decreases the heart rate. Increase in heart rate above 100 per minute is known as [Select] , while a decrease in heart rate below 60 per minute is known as (Select
