Breathing Control Mechanisms

Front

Neural chemo receptors send impulses to the medulla oblongata in the brain.

Back

This decides the breathing rate and sends regular impulses to the diaphragm.

Front

During exercise, impulses increase.

Back

This increases the breathing rate and stimulates forced inspiration and expiration.

Front

Chemical control of breathing involves CO₂ dissolving into plasma.

Back

Increased CO₂ increases acidity, leading to an increased need to breathe.

Front

During exercise, greater amounts of CO₂ are produced.

Back

This results in deeper breathing.

Front

Chemo-receptors detect pH and CO₂ levels.

Back

They play a crucial role in regulating breathing.

Front

Oxygen levels are monitored by peripheral chemo-receptors.

Back

These receptors are located in the carotid and aortic bodies.

Front

Hyperventilation can lead to decreased CO₂ levels.

Back

This results in respiratory alkalosis, causing dizziness and tingling.

Front

The medulla oblongata adjusts breathing based on CO₂ levels.

Back

It ensures homeostasis by maintaining proper gas exchange.
