Study Notes
Respiration: Function & Regulation
- Primary Function: Gas exchange (oxygen and carbon dioxide).
- Gas Exchange Location: Alveoli in the lungs.
- Main Breathing Muscle: Diaphragm.
- Breathing Rhythm Control: Medulla Oblongata in the brain.
- Pneumotaxic Center Function: Regulates breathing rate.
- Central Chemoreceptors Detect: Carbon dioxide and pH levels in the blood.
- Peripheral Chemoreceptors Detect: Low oxygen levels in the blood.
- Increased Breathing Rate Stimulus: Increased carbon dioxide levels and decreased pH.
- Medulla Oblongata Role: Initiates the basic rhythm of breathing.
- Non-Respiratory System Component: Liver.
- Exercise Breathing Response: Increases.
- Gas Exchange Structure: Alveoli.
- High Blood Carbon Dioxide Response: Increased breathing rate.
- Breathing Process Term: Pulmonary ventilation.
- Diaphragm Control Nerve: Phrenic nerve.
