ATI TEAS Respiratory System Exam
Questions With 100% Verified Answers
respiratory system -
correct answer ✅-primary function is to facilitate gas exchange b/t
the body and external environment, and to provide oxygen to the
body by working w/ the cardiovascular system
-consists of nasal cavity, pharynx, epiglottis, larynx, trachea, lungs,
bronchioles, bronchi, diaphragm, and alveolus
-system of organs that oxygenate blood and release carbon dioxide
respiratory system and cardiovascular system work together -
correct answer ✅-oxygen diffuses into the body through the lungs
and is disseminated throughout the body by the circulatory system
to be used for cellular metabolism
-carbon dioxide, the waste product of cellular metabolism, is
returned to the lungs by the circulatory system, and the lungs
release it to the environment
pharynx -
correct answer ✅-beginning back of throat and ending at glottis;
-shared with food
epiglottis -
correct answer ✅-flap of cartilage that covers the entrance to the
,ATI TEAS Respiratory System Exam
Questions With 100% Verified Answers
pharynx during swallowing, preventing liquids and food from
entering the respiratory tract and trachea
larynx -
correct answer ✅-traveling past the epiglottis, air then passes
through the larynx
-ALSO called the voice box!
-sound produced when air from lungs forced against vocal cords.
trachea -
correct answer ✅-the tube that carries air from the mouth and
nasal cavities to the lungs
-rigid tube of cartilaginous rings
-anterior to esophogus
-the trachea splits into 2 bronchi
-starts at the larynx
bronchi -
correct answer ✅-main passageways to the left and right lung
-originating where the trachea splits, passages that carry air to the
left and right lungs
, ATI TEAS Respiratory System Exam
Questions With 100% Verified Answers
-as the bronchi move deeper into the lungs, the bronchi split into
smaller tubes known as bronchioles
-plural: bronchus
bronchioles -
correct answer ✅-terminate at the alveoli
-smaller passages formed from branching of the bronchi (tertiary &
microscopic bronchioles) that carry air to the alveoli
alveoli -
correct answer ✅-300,000,000 small sacs only one epithelial cell
thick to allow for diffusion into 1 cell thick capillaries.
-plural: alveolus
