A#136: Quizizz Respiratory System Flashcards

Front

Respiration

Back

The process of gas exchange – the release of CO2 and the uptake of O2 between the lungs and the environment.

Front

Respiratory system

Back

Consists of the nose, pharynx, larynx, trachea, bronchi, and lungs.

Air → nose → pharynx → trachea → lungs → bronchus → bronchioles → alveoli

Front

Pharynx

Back

A passageway for both air and food. Air moves from the pharynx into the trachea (windpipe).

Front

Epiglottis

Back

A flap of tissue that covers the entrance to the trachea when you swallow.

Front

Larynx

Back

Contains two highly elastic folds of tissue known as the vocal cords.

Front

Bronchi

Back

2 large passageways in the chest cavity that lead into the lungs

Front

Bronchioles

Back

Small subdivisions of the bronchi

Front

Alveoli

Back

Tiny air sacs at the end of the bronchioles clustered into bunches and surrounded by capillaries

Front

Gas Exchange (Lungs)

Back

Oxygen diffuses from high concentration in the alveoli to low concentration in the blood

CO2 diffuses from high concentration on the blood to low concentration in the alveoli

Front

Gas Exchange (Muscles)

Back

Oxygen diffuses from high concentration in the blood to low concentration in the muscles

CO2 diffuses from high concentration in the muscles to low concentration in the blood.
