Study Notes

Air Processing in the Respiratory System

Air entering the nasal cavity is warmed, filtered, and moistened.
Cilia are tiny hairlike structures that trap germs and push them toward the esophagus.

Pharynx Structure

The pharynx consists of three sections: nasopharynx, oropharynx, and laryngopharynx.

Speech Production

Speech is produced when air enters the lungs and causes vocal cords to vibrate.

Protective Mechanisms

The epiglottis prevents food and liquids from entering the respiratory tract.

Alveoli Functionality

Alveoli contain a rich network of blood capillaries, allowing for gas exchange between the bloodstream and lungs.
The inner surfaces of alveoli are covered with a lipid substance called surfactant.

Lung Anatomy

The left lung is smaller than the right lung due to the positioning of the heart on the left side of the chest.

Breathing Processes

Inspiration refers to the act of breathing in air, while expiration is the act of exhaling.
Ventilation is the overall process of breathing.

Gas Exchange

External respiration involves the exchange of oxygen and carbon dioxide between the alveoli and lungs.
Internal respiration is the exchange of these gases between the bloodstream and body tissues.

Cellular Respiration

Cellular respiration involves the exchange of oxygen and carbon within cells to produce energy, water, and carbon dioxide.

Respiratory Regulation

The respiratory center in the medulla oblongata increases the rate of respiration in response to higher carbon levels or lower oxygen levels in the blood.

Common Respiratory Conditions

Bronchitis is the inflammation of bronchi and bronchioles.
Influenza is a highly contagious viral infection affecting the respiratory system.
Sinusitis refers to the inflammation of the mucous membrane lining the sinus.
Emphysema involves the deterioration of alveolar walls, resulting in loss of elasticity.
Epistaxis is commonly known as a nosebleed.
Tuberculosis is an infectious lung disease caused by bacteria.
Asthma consists of bronchospasms that narrow the openings of the bronchioles.
Rhinitis is the inflammation of nasal mucous membranes.
Chronic Obstructive Pulmonary Disease (COPD) includes any chronic lung disease that obstructs airways.
Pleurisy is the inflammation of the membranes surrounding the lungs.
Laryngitis is the inflammation of the voice box and vocal cords.

Treatment and Monitoring

CPAP (Continuous Positive Airway Pressure) therapy uses air pressure to keep airways open and is often used for sleep apnea.
Upper respiratory infections result in inflammation of the mucous lining of the upper respiratory tract.
Crepitations are abnormal sounds heard in the lungs.
Thoracentesis is a procedure to withdraw fluid from the pleural space using a needle.
Pneumonia is characterized by inflammation or infection of the lungs.
Obstructive sleep apnea is caused by blockages in the air passages during sleep, while central sleep apnea arises from disorders in the respiratory center of the brain.

Lung Anatomy Details

The visceral pleura is attached to the surface of the lungs, with three lobes in the right lung.
The parietal pleura is attached to the chest wall, with two lobes in the left lung.
