The neural control of breathing refers to the complex mechanisms in the brain and spinal cord that regulate the rhythm and depth of breathing. It involves specialized centers in the brainstem that receive input from sensors monitoring blood oxygen and carbon dioxide levels, as well as other factors like physical activity and emotional state, to adjust breathing accordingly. This control ensures that the body receives enough oxygen and expels carbon dioxide to maintain homeostasis.

Severing the neural connections between the pneumotaxic center and apneustic center can disrupt the normal regulation of breathing. This disruption can lead to irregular breathing patterns, such as prolonged or insufficient breathing cycles, and can result in abnormalities in breathing rhythm and volume control. Coordination between these two centers is necessary for proper breathing regulation.

No; breathing is a biological function used to draw oxygen into the body, where it can be used for chemical reactions. Respiration of cells in the body is, however, a chemical activity, wherein the oxgen reacts with the glucose (and other sugars) from food.
Stimulus
breathing tobacco smoke
