Question

Which part of the brain controls breathing?

Answer 1

Breathing:

1. Breathing is an automatic and rhythmic act produced by networks of neurons in the brainstem (pons and medulla).
2. Carbon dioxide is exhaled outside while oxygen is simultaneously inhaled from the air (outer environment).
3. Breathing movements (inhaling oxygen and exhaling carbon dioxide) are triggered by the body's carbon dioxide and oxygen ratio.
4. The majority of body cells and tissues need oxygen to perform their metabolic functions.
5. Carbon dioxide, however, is created as a waste product of biological processes during certain metabolic activities.
6. As a result, a combination of high carbon dioxide levels and low oxygen levels would cause the body to exhale carbon dioxide and inhale oxygen.

Breathing controlled by:

1. This is normally controlled by the medulla oblongata, a region of the hindbrain.
2. The medulla oblongata sends signals to the heart and diaphragm in reaction to carbon dioxide and oxygen levels, allowing for easier breathing.
3. Pons regulates the breathing rate.

Final Answer: Medulla oblongata of the brain controls breathing.
