Study Notes
Respiratory Anatomy
- The term "pulmonary" refers to the lungs
- Bronchi are airway tubes that branch from the trachea, with "bronchi" being the plural form and "bronchus" being the singular form
- Alveoli are small air sacs where gas exchange occurs, with "alveoli" being the plural form and "alveolus" being the singular form
- The lumen is the inner space within a tubular organ, such as the bronchi, and can be thought of as an "opening" or cavity
- The hilus or hilum is an indentation in an organ, including the lung, kidney, and spleen, where blood vessels, ducts, and other structures enter or leave the organ
- Cilia are small hair-like projections that extend from the cell membrane, playing a role in the respiratory system

Respiratory System Functions
- The primary respiratory function is to provide oxygen (O2) to and remove carbon dioxide (CO2) from tissues
Non-Respiratory Functions
- Vocalisation occurs via vocal cords in the larynx
- Thermoregulation (temperature regulation) is performed through panting to lose heat and counter-current heat exchange to retain heat
- Olfaction (smell) is facilitated by the olfactory nerve, which has a close association with the nasal cavity

Dividing the Respiratory System into Upper and Lower
- Dividing the respiratory system into upper and lower is crucial for accurate diagnosis and treatment of diseases.
- Different diseases affect different parts of the respiratory system, leading to distinct clinical signs and requiring specific tests and treatments.
Upper Respiratory Tract
- Infections like Kennel cough (in dogs) and cat flu (in cats) primarily affect the upper respiratory tract.
- Omicron variant of COVID-19 tends to infect the upper respiratory tract.
Lower Respiratory Tract
- Diseases like asthma and pulmonary oedema (fluid in the lungs causing cough) affect the lower respiratory tract.
- Pulmonary oedema is a serious condition that can be life-threatening in emergency situations.
- Delta variant of COVID-19 tends to infect the lower respiratory tract.
Importance of Accurate Diagnosis
- Accurate diagnosis of the affected respiratory tract region is critical in emergency situations to ensure proper treatment and prevent mismanagement of diseases.
