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 respiratory system is responsible for breathing and consists of the respiratory tract and lungs.
The nasal cavity filters, moistens, and warms the air and is the main entrance to the respiratory system.

Breathing in involves the ribcage lifting up and out and the lungs being pulled up and out, while breathing out involves the ribcage sinking and the lungs contracting.
The rate of breathing is determined by the amount of carbon dioxide that must be expelled from the blood stream.
Oxygen from the lungs forms a compound with hemoglobin called oxyhemoglobin, which is transported to cells of the body, where it is exchanged for carbon dioxide.
The exchange of oxygen for carbon dioxide occurs in the alveoli, surrounded by capillaries.
