ATI TEAS Respiratory System Exam Newest 2026
Questions and Correct Detailed Answers Already
Graded A+
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
gas exchange in alveoli - CORRECT ANSWER--the exchange of carbon dioxide
for oxygen relies at alveoli relies on simple diffusion
-due to the millions of alveoli in the lung, the surface area for gas exchange is
estimated to be b/t 50 to 75 square meters (size of tennis court), allowing large
amounts of gases to be exchanged quickly
, -the diffusion of gases is driven by a concentration gradient
simple diffusion - CORRECT ANSWER-movement of membrane-permeable
solutes down a concentration gradient
diffusion rate - CORRECT ANSWER--speed of movement down a concentration
gradient
-directionally proportional to the surface area and the concentration gradient and
is inversely proportional to the distance b/t the 2 gases
concentration gradient - CORRECT ANSWER--the partial pressure of oxygen is
high in the airspace of the lungs and low in the blood, so oxygen will diffuse down
its concentration gradient into the blood
-the partial pressure of carbon dioxide is higher in the blood than in the airspace
in the lungs, so it will diffuse down its concentration gradient out of the blood
ventilation rate - CORRECT ANSWER--controlled by medulla oblongata, located
in the brainstem
-monitors blood pH and carbon dioxide concentration in the blood
-carbon dioxide directly affects pH through the bicarbonate blood buffering
system
