The respiratory system (pulmonary system)
Lungs and respiratory passageways that collect oxygen from external environment and transports it to bloodstream.
• breathing is the process of moving air in and out of the body and requires optimal functioning of the respiratory pump and all its components.
Respiratory pump

Inspiration
