Study Notes
Respiratory System
- Breathing is essential for life, representing dramatic moments in human experience.
- Respiration is vital for ATP synthesis, as most metabolic processes directly or indirectly depend on ATP.
- Oxygen is necessary for ATP synthesis and creates carbon dioxide. Respiration is necessary for replacing oxygen and removing carbon dioxide.
- The respiratory system primarily involves tubes delivering air to the lungs. Oxygen diffuses into the blood, and carbon dioxide is removed. This system's key function is gas exchange.
Main Function
- The respiratory system provides oxygen to the blood and removes carbon dioxide.
- It has several functions, including gas exchange, communication (speech), olfaction (smelling), acid-base balance, and regulation of blood pressure.
- It aids in the expulsion of abdominal contents.
Upper Respiratory Tract
- The nose filters, warms, and moistens air.
- The pharynx (throat) is a common passageway for air, food, and liquid.
- The larynx (voice box) produces sound.
- The trachea (windpipe) is the main airway.
- The bronchi branch into smaller airways.
- Alveoli are air sacs for gas exchange.
Lower Respiratory Tract
- The trachea's 12cm, 2.5cm diameter tube is supported by cartilage.
- The trachea branches into two main bronchi, one for each lung.
- The trachea is situated anterior to the esophagus.
- The bronchi further divide into smaller bronchioles, terminating in alveoli.
Lungs
- Lungs consist of three faces: diaphragmatic, costal, and mediastinal.
- The structures entering and exiting the lung form the root (radix) pulmonis.
- The hilum is where these structures enter the lung.
- Lungs have lobes (right: three, left: two), separated by fissures.
Root of the Lung
- The mediastinal surface of the lungs has a slit called the hilum.
- The root of the lung contains the main bronchus, blood vessels, and nerves.
- The structures within the root supply the lungs.
Pleura
- The pleura is a double-layered membrane surrounding the lungs.
- Visceral pleura surrounds the lung tissue.
- Parietal pleura surrounds the visceral pleura externally and lines the thoracic cavity.
- The pleural cavity contains serous fluid to prevent friction.
Additional Notes
- Mouth: Airway for both air and food.
- Epiglottis: Closes the trachea during swallowing.
- Larynx: Produces sound; keeps food and liquids out of respiratory tract.
- Nasal Cavity: Warms, filters, and humidifies inhaled air.
- Pharynx: Passageway for air, food, and liquid.
- Trachea: Air passage.
- Bronchi: Air passages branching from trachea to lungs.
- Alveoli: Gas exchange sites in the lungs.
- Diaphragm: Muscle controlling breathing.
