Anatomy & Physiology Respiratory #19
Which system of the body consists of the airway and the lungs?
- Digestive system
The digestive system is made up of the gastrointestinal (GI) or digestive tract in addition to the gallbladder, liver, and pancreas which are accessory structures that facilitate normal function for this system.
- Circulatory system
The circulatory (cardiovascular) system consists of blood, blood vessels, and the heart (cardiac muscle). The function of this system is to carry blood away from, and towards, the cardiac muscle.
- Respiratory system
The respiratory system consists of the airway, an upper respiratory tract structure, and the lungs, a lower respiratory tract structure. The function of this system is ventilation which facilitates gas exchange.
- Neurological system
The nervous (neurologic) system is composed of the brain and spinal cord. In addition to these two structures, this system also includes the peripheral nervous system (PNS) which is divided into both sympathetic and parasympathetic parts.
All body systems of the body work together to maintain homeostasis. Each system has specific structures and functions.
The respiratory system consists of two tracts, the upper respiratory tract and the lower respiratory tract. Each tract has specific structures and functions. The airway is an upper respiratory tract structure, while the lungs are a lower respiratory tract structure.
