Study Notes
Upper Respiratory Tract
- Includes the paranasal sinuses, pharynx, tonsils, adenoids, larynx, and trachea.
- Serves as the first line of defense against pathogens through filtering, warming, and humidifying inhaled air.
Lower Respiratory Tract
- Comprises the lungs, bronchi, and alveoli.
- Alveoli are essential for gas exchange, allowing oxygen and carbon dioxide to move between the air and blood.
Functions of the Respiratory System
- Oxygen Transport: Oxygen is delivered to cells and carbon dioxide is removed via the circulatory system.
- Ventilation: Involves the mechanical processes to move oxygen into the lungs and expel carbon dioxide.
- Respiration: Focuses on the movement of oxygen from the atmosphere into the cellular environment for metabolic needs.
- Gas Exchange: Major role of the pulmonary system; transfers oxygen to cells and removes carbon dioxide, essential for cellular respiration.
Additional Terms
- Dyspnea: A medical term referring to difficulty in breathing, often indicative of respiratory problems.
- Arterial Blood Gas (ABG): A diagnostic test that evaluates oxygenation, ventilation, and acid-base balance in the blood, typically obtained through arterial puncture at the radial, brachial, or femoral artery.
