The breathing center is most sensitive to CO2 (carbon dioxide).
The brain controls the human body. I don't know if the answer above is supposed to be sarcastic, or just someone who doesn't know and wanted to add something anyway. That is an incredibly useless answer. In part, the brain controls movement of all body parts, temperature, heart beat, interprets feeling and pain, breathing, when you sleep it regulates breathing and controls the heart, and does much more, but since I'm not a doctor, that is about all I know.
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.
The brain is often considered the most important organ of the body. It controls all bodily functions, including thoughts, movements, and emotions. Without the brain, the body would not be able to function properly.
Of all of the chemicals influencing respiration, CO2 is the most potent and the most closely controlled. Normally, arterial Pco2 is 40 mm Hg and is maintained with in + - 3 mm Hg of this level by an exquisitely sensitive homeostatic mechanism that is mediated mainly by the effect that rising Co2 have on the central chemoreceptors of the brain stem.
The brain stem. It consists of three parts; the midbrain, pons, and medulla oblongatta. It houses the respiratory and cardiac centers. Without it you would not be able to live.
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.
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!
The heart and the brain...
Brain.
The most important signal that the brain uses to regulate breathing rate is the level of carbon dioxide in the blood. When carbon dioxide levels rise, this triggers the brain to increase the breathing rate to expel excess carbon dioxide and bring more oxygen into the body.
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
