The breathing center is most sensitive to CO2 (carbon dioxide).
levels of carbon dioxide in the blood. When carbon dioxide levels rise, the breathing center stimulates the muscles of respiration to increase breathing rate and depth. This helps to eliminate excess carbon dioxide and restore a balance in blood gas levels.
the brain because it is the center of life
Q - What is the most important part of the brain?A - This answer is opinionated based on facts.Probably the medulla because it is the part of the brain that controls involuntary activities such as breathing, heart beat, & digestion. It also contacts with the spinal cord and spinal nerves. :)*Other parts of the brain include-Cerebrum,Cerebellum.
It contains centers that control heart rate, blood pressure, breathing, swallowing (and vomiting), among others.
The bitter ones are the most sensitive.
Circulating CO2 concentration
Chemicals - most important are the concentrations of CO2, hydrogen ions and O2 in the blood. Chemoreceptors are located in the respiratory center, the carotid bodies and the aortic bodies which detect the levels. Inflation Reflex- stretch receptors in the visceral pleurae are sensitive to the degree of stretching by the lungs. Higher Brain Centers - Impulses from higher brain centers may affect respiratory center. Body Temperature - an increase in body temp, increases the breathing rate.
hypothalmus
The organs most sensitive to deprivation of oxygen are the heart and the brain.
Brain and lungs
brain and kidneys
Your eyes are an extension of your brain. In fact most of your brain is light sensitive, and will respond by recalling memories!
Brain.
The heart and the brain...
heart because if heart is not present in body brain do not get blood and so brain will damage
the brain controls most functions in the body.
medulla oblongata
