Study Notes
Composition of Air
- Nitrogen (Azote) comprises 78% of ambient air.
- Oxygen accounts for approximately 20% of ambient air.
- Carbon dioxide (CO2) is found at 0.03%.
- Noble gases such as argon, neon, and krypton make up about 1.7%.
Structure of the Lungs
- Each lung is attached to the posterior wall of the thoracic cavity.
- The upper part of each lung is called the apex, located near the clavicle.
- The lower part is called the base, positioned near the diaphragm.
- The left lung has 2 lobes: upper and lower.
- The right lung contains 3 lobes: upper, middle, and lower.
Respiratory System Anatomy
- Conducting zone organs include the nose (nez), pharynx, larynx, trachea, and bronchi.
Mechanism of Respiration
- The process involves four stages; the first stage is pulmonary ventilation.
- Pulmonary ventilation comprises 2 phases: inspiration and expiration.
Inspiration Mechanics
- During inspiration, the diaphragm contracts and descends, increasing the height of the thoracic cavity.
- Approximately 500 milliliters of air enters the lungs during a normal inspiration.
Expiration Process
- Expiration is a passive process relying on the elasticity of the lungs.
- Forced expiration occurs through the contraction of the abdominal wall to expel more air.
Gas Exchange
- External respiration involves gas exchange between capillaries and the alveoli in the lungs.
- Internal respiration refers to gas exchange between capillaries and body tissues.
Respiratory and Cardiovascular Rates and Functions
- The normal respiratory rate for adults is 12-20 respirations per minute.
- A respiratory rate above 20 breaths per minute may indicate respiratory distress.
- The cardiovascular system facilitates the transport of oxygen, carbon dioxide, wastes, hormones, and nutrients.
- The heart, the center of the cardiovascular system, is situated in the thoracic cavity between the two lungs, predominantly on the left side of the body.

Description
This quiz covers the primary functions of the respiratory system, such as bringing oxygen from the ambient air into the body, as well as the composition of ambient air. It also includes information about the organs of the respiratory system, divided into the zones of conduction and respiration.
