What is the system which includes the lungs and airways?
The system which includes the lungs and airways is called the respiratory system.
The lungs, airways, diaphragm, windpipe, throat, mouth and nasal passages are all part of the respiratory system. Respiration is the process of breathing in and out through this system. Oxygen is taken into the body through the airways absorbed into the lungs, then transported through the body in the blood or bloodstream. The lungs also give out carbon dioxide into the atmosphere.
The respiratory system, of mammals in particular, consists of respiratory airways, lungs and muscles concerned with respiration. The respiratory airways include the trachea, bronchiole, alveoli. Lungs perform function of exchange of gases. Muscles of the diaphragm contribute to breathing activity.

The respiratory system is the group of tissues and organs in the body that enables the body to breathe. This system includes airways, lungs and the blood vessels and muscles attached to them that work together so the body can breathe. The respiratory system's primary function is to supply oxygen to all the parts of the body.
Why does the forced expiratory volume percentage decrease as the radius of the airways is decreased?
The respiratory system is a structure of organs used for the process of respiration and the intake and exchange of oxygen and carbon dioxide between an organism and the environment. The parts of the respiratory system are the upper respiratory tract, lower respiratory tract, airways, lungs and diaphragm.
