Study Notes
- Alveoli are small sacs responsible for gas exchange and considered the functional unit of the lungs.
- The trachea bifurcates at the carina to form the left and right bronchi.
- Capillaries act as a connection between arteries and veins, facilitating diffusion in the respiratory system based on gradient increases.
- Ventilation is controlled by respiratory centers in the medulla oblongata and pons, responding to changes in carbon dioxide levels and hydrogen ion concentrations.
- Cilia are fine hairs in the nose that move mucus to the back of the throat.
- The diaphragm, an accessory structure, separates the thoracic and abdominal cavities.
- The epiglottis is a cartilaginous valve flap that covers the opening of the larynx during swallowing.
- The nasal cavity contains bones, cartilage, septum, and cilia.
- Nostrils are external openings that admit air to the lungs and smell to the olfactory nerves.
- Oxygen concentration is higher in alveoli than in capillaries during inspiration.
- The pharynx, divided into three continuous areas, carries air from the nose to the larynx and food from the mouth to the esophagus.
- The pleural membrane consists of the visceral pleura covering the lung surface and the parietal pleura covering the chest wall.
- Respiration involves exchanging oxygen and carbon dioxide between atmospheric air, blood, and cells.
- The trachea is a hollow tube composed of smooth muscles supported by C-shaped cartilage.
- Key concepts include gas exchange between organs and pulmonary circulation, neurologic control of ventilation, and mechanisms like diffusion and alveolar respiration.
Studying That Suits You
Use AI to generate personalized quizzes and flashcards to suit your learning preferences.
Description
Test your knowledge on respiratory system vocabulary including terms like hypoxia, hypoxemia, hypercapnia, and diseases such as asthma, chronic bronchitis, and lung elasticity loss. Also, assess your understanding of conditions like fibrosis, atelectasis, kyphosis, and scoliosis.
