M2 RS Flashcards
Respiratory System
呼吸系統
Ventilation (V)
The exchange of the air between the atmosphere and the lungs.
External Respiration
The movement of gases between the environment and
the cells of the body.
Internal Respiration
The movement of the gases from the lungs, through the blood stream and to the cells.
The upper respiratory system consists⋯
nose, pharynx, and associated structures
The lower respiratory system consists⋯
larynx, trachea, bronchi, and lungs
Pharynx
咽
Nasopharynx
鼻咽
Oropharynx
口咽
Larynogopharynx
喉咽
Pharyngeal tonsil
咽部扁桃體
Tubal tonsil
咽鼓管扁桃體
Palatin tonsil
顎扁桃體
Isthmus
峽部 a narrow structure separates two parts
Fauces
喉
Lingual tonsil
舌扁桃體
Hyoid bone
舌骨Anchor point for muscles needed for swallowing and speech
Jugular notch
頸靜脈切跡
Used medically to assess venous pressure, inserting central venous catheter, observing the thyroid gland, radiological measurements
catheter
導管
Thyroid gland
甲狀腺
Larynx
喉
Epiglottis
會厭Prevents food and liquids from entering the airway during swallowing
glottis
聲門
Trachea
氣管
mediastinum
a space in your chest that holds your heart and other important structures
Trachea runs from end of larynx (C6) to⋯
T4/T5, where it bifurcates into the primary bronchi
Function of Trachea
filter, warm, humidify air
hyaline
透明的
Trachea contains⋯ posteriorly
15-20 U-shaped hyaline cartilages & trachealis muscle, and Annular ligaments connect cartilage rings
trachealis muscle
氣管肌
Annular
環形
ligament
韌帶
Cilia
纖毛
ciliary escalator
Cilia move rhythmically
The Pleura Membranes
胸膜
Visceral Pleura
臟層胸膜Covers the surface of the lungs
Function of Visceral Pleura
• Protects from friction摩擦
• Helps maintain shape
• Prevent lung collapse崩塌
• Synchronising同步 movement with the chest wall

Parietal Pleura
壁層胸膜Covers not only the lungs, but heart and major blood vessels
Functions of Parietal Pleura
• Lines the thoracic cavity
• Protects from friction
• Integrity完整性 of pleural cavity
Pleural Fluid
腔積水
Pleural Cavity
胸膜腔with Pleural Fluid
Functions of pleural cavity with pleural fluid
• creates a moist, slippery surface – easy sliding and ↓ friction
• holds the lungs tight against the thoracic wall.
