Pulmonary System L2

Ventilation is regulated by: (Select all of the following)

• Inspiration

• Medulla Oblongata

• Bar-Chemo receptors

• Nervous System

• Boyle's Law

Sensitive to CO2 (acidic/pH)

• Medulla Oblongata

• Baro-Chemo receptors

• Nervous System

• Respiration

Increase ventilation to maintain blood O2

• Medulla Oblongata

• Exercise

• Baro-/Chemo-receptors

• Respiration

Breathing regulation occurs by a dense network of bilateral, symmetrical neurons located in the ventrolateral area of the

• Pons

• Cerebellum

• Medulla Oblongata

• Cerebrum

• -Occurs when blood O2 decreases

• - Caused by airway obstruction, metabolic imbalances, psychological stress (anxiety), mechanical restriction, cardiac/pulmonary pathology

• Dyspnea

• Cough

• Hemoptysis

• Cyanosis

• Wheezing

Reflex contraction of diaphragm to eliminate airway irritation

• Dyspnea

• Cough

• Hemoptysis

• Cyanosis

• Wheezing

Due to narrowed/constricted airways; expiration > inspiration' if both present=BAD
