The two lungs are the primary organs of the respiratory system. Other components of the respiratory system conduct air to the lungs, such as the trachea (windpipe) which branches into smaller structures called bronchi.
The process of breathing (respiration) is divided into two distinct phases, inspiration (inhalation) and expiration (exhalation). During inspiration, the diaphragm contracts and pulls downward while the muscles between the ribs contract and pull upward. This increases the size of the thoracic cavity and decreases the pressure inside. As a result, air rushes in and fills the lungs.
During expiration, the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases. As a result, the lungs contract and air is forced out.

What are the effects of breathing in saturated air on the human body?
Breathing in saturated air can lead to increased moisture in the lungs, making it harder for the body to exchange oxygen and carbon dioxide. This can result in difficulty breathing, coughing, and potential respiratory issues.
Does size affect breathing?
Yes, the size of an organism can affect its breathing. Smaller organisms typically have a higher surface area-to-volume ratio, which means they have a larger surface area relative to their volume. This can impact how efficiently they exchange gases with their environment, affecting their breathing.
What is the name of the machine?
One name for a breathing machine is a ventilator. Old timey breathing machines were called "iron lungs." Some people consider CPAP machines and nebulizers breathing machines, but they do not breathe for you.

What are the two phases of breathing?
The two phases of breathing are breathing in and breathing out. Humans breathe in oxygen and they release carbon dioxide when they breathe out.
What is spontaneous breathing?
