The respiratory centre in the brain is stimulate by
The respiratory centre in the brain is stimulate by
The correct option is C Carbon dioxide content in arterial blood
Carbon dioxide level in blood
Chemosensitive area which is highly sensitive to hydrogen ions as well as carbon dioxide is located adjacent to the rhythm centre. This rhythm centre is a specialised region in the medulla (part of hindbrain) which helps in regulating respiration rate.
Receptors associated with the aortic arch and carotid artery are called the aortic body and carotid body respectively. The carotid bodies are located on the bifurcation of one of the main arteries of the neck called the carotid artery.
Carbon dioxide level in blood
The aortic body is located on the aortic arch, which is the portion of the main artery (aorta) that bends between the ascending and descending part of the aorta. These can recognise changes in carbon dioxide and hydrogen ion concentration in the blood and send necessary signals to the respiratory rhythm centre for remedial actions. Oxygen concentrations are not generally detected by these chemoreceptors.
Final answer
(B) Carbon dioxide content in arterial blood
