    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.
