Study Notes
An Overview of the Respiratory System
- The respiratory system is responsible for breathing and consists of the respiratory tract and lungs.
- The nasal cavity is the main entrance to the respiratory system and is lined with a mucous membrane that filters, moistens, and warms the air.
- The pharynx connects the nasal passage with the larynx and also connects the mouth with the esophagus.
- The larynx is situated in the neck in front of the pharynx and is responsible for producing sound.
- There are two lungs divided into lobes, where the exchange of carbon dioxide for oxygen takes place.
- The trachea divides into two main tubes called bronchi, which go into one lung lobe and divide into increasingly smaller airways called bronchioles.
- Each bronchiole ends in an alveolus, of which there are about 300 million in each lung lobe.
- The pleura is a thin membranous covering that surrounds each lung and contains a small amount of fluid to lubricate the lungs.
- Breathing in involves the ribcage lifting up and out, while breathing out involves the ribcage sinking and the lungs contracting and squeezing out air.
- Oxygen from the lungs forms a compound with hemoglobin, called oxyhemoglobin, which is transported to cells and exchanged for carbon dioxide.
- The exchange of oxygen for carbon dioxide takes place in the alveoli, which are vulnerable to particles floating in the air that may interfere with lung infections.
- The respiratory system is susceptible to infections, including nasal infections, pharynx infections, and lung infections caused by bacteria, irritants, and allergens.

- The rate of breathing is determined by the amount of carbon dioxide that needs to be expelled.
- Oxygen from the lungs forms oxyhemoglobin with hemoglobin and is transported to cells, while carbon dioxide forms carboxyhemoglobin and goes back to the lungs.
- The exchange of oxygen and carbon dioxide occurs in the alveoli, surrounded by capillaries.
- The respiratory system is vulnerable to particles like bacteria, tobacco smoke, and allergens that can cause infections and diseases like pneumonia, lung cancer, and asthma.
- The nasal cavity is also a sensory organ responsible for the sense of smell.
- The pharynx has a complex function of connecting the respiratory and digestive systems, which can be infected by pathogens that spread in both directions.
Overview of the Respiratory System
- The respiratory system supplies oxygen to the erythrocyte pigment hemoglobin and removes carbon dioxide.
- It comprises the respiratory tract and lungs, including the nasal cavity, pharynx, larynx, trachea, bronchi, and bronchioles.
- The nasal cavity filters, moistens, and warms the air, and contains tiny blood vessels and protective hairs.
- The pharynx connects the nasal passage to the larynx and the mouth to the esophagus.
