Arterial blood has higher oxygen and low carbon dioxide. If concentration of carbon dioxide is more in arterial blood then respiratory center will regulate breathing pattern. Venous blood has already high concentration of Carbon dioxide.
Respiratory center also utilize oxygen therefore blood entering respiratory center will give accurate concentration of oxygen.
A chemosensitive area is situated adjacent to the rhythm centre which is highly sensitive to CO2 and hydrogen ions. Increase in these substances can activate this centre, which in turn can signal the rhythm centre to make necessary adjustments in the respiratory process

- **Arterial blood entering the respiratory centre**
The respiratory centre is a group of neurons located in the brainstem that controls the rate and depth of breathing. When the body requires more oxygen, such as during exercise or in response to stress, the respiratory centre signals for faster breathing.
- **Role of arterial blood**
Arterial blood plays a crucial role in providing feedback to the respiratory centre about the body's oxygen and carbon dioxide levels. As blood flows through the arteries, it picks up oxygen from the lungs and transports it to the body's tissues. At the same time, it picks up carbon dioxide produced by the cells and carries it back to the lungs to be exhaled.
- **Chemoreceptors detect changes**
Specialized cells called chemoreceptors in the arteries detect changes in the levels of oxygen and carbon dioxide in the blood. When the oxygen levels are low or the carbon dioxide levels are high, the chemoreceptors send signals to the respiratory centre to increase the rate and depth of breathing.
- **Arterial blood entering the respiratory centre triggers faster breathing**
Therefore, arterial blood entering the respiratory centre provides essential feedback about the body's respiratory needs. When the respiratory centre receives signals from the arterial blood indicating a need for more oxygen or a need to eliminate excess carbon dioxide, it responds by increasing the breathing rate. This results in faster breathing to meet the body's demands for oxygen and to remove carbon dioxide efficiently.
