Q

respiratory system

A

system of organs (lungs and passageways) that collects oxygen from external environment and transports to bloodstream

18
Q

respiratory pump

A

composed of skeletal structures (bones) and soft tissues (muscles) that work together to allow proper respiratory mechanics to occur

19
Q

inspiration

A

process of actively contracting inspiratory muscles to move air into body

20
Q

expiration

A

process of actively or passively relaxing inspiratory muscles to move air our of body

21
Q

diffusion

A

process of getting oxygen from environment to the tissues of the body

22
Q
