Answer:
Respiratory System
Step-by-step explanation:
The different organs in the body are separated into different groups. Such kind of group is called an "organ system."
There are 11 major organ systems in the body and these are: Integumentary, Muscular, Skeletal, Digestive, Nervous, Urinary, Respiratory, Lymphatic, Cardiovascular, Reproductive and Endocrine.
The trachea, larynx, pharynx and lungs are organs that belong to the "Respiratory System." This organ system is responsible for the person's breathing. The organs work hand-in-hand in order to properly exchange oxygen and carbon dioxide during the process of breathing.
