Flashcards- Lungs, Chest Wall,
Heart, and Peripheral
Vascular/Lymphatics Exam
Questions and Answers 100%
PASS
What are the main functions of the lungs?—ANSWER--1. O2 to body for energy
2. Remove CO2 as energy waste product
3. Maintain homeostasis of acid-base balance
4. Maintenance of heat exchange (not so much in humans)
What bones make up the thoracic cage?—ANSWER--Sternum
12 pairs of ribs
12 thoracic vertebrae
Where is the suprasternal notch located?—ANSWER--Hollow, U-shaped depression just
above the sternum.
Where is the sternal angle (angle of Louis) located?—ANSWER--Where the manubrium of
the sternum meets the body of the sternum; continuous with the second rib.
, What is the sternal angle a landmark for?—ANSWER--The site of tracheal bifurcation into
the right and left main bronchi AND the upper border of the atria of the heart
What is the costal angle and what does it signify?—ANSWER--The right and left costal
margins form an angle where they meet at the xiphoid process; they should make a 90
degree or less angle; increases when rib cage chronically over-inflated (emphysema)
Where are the apexes and bases of the lungs found on the anterior chest?—ANSWER--Apex:
3-4 cm above the inner 1/3 of the clavicles
Base: About the 6th rib, MCL
Where are the apexes and bases of the lungs found on the posterior chest?—ANSWER--
Apex: C7
Base: T10 (drops to T12 with inspiration)
What are the major differences between the R and L lungs?—ANSWER--R lung: shorter
because of underlying liver; 3 lobes
L lung: narrower and longer; 2 lobes
Where are the upper and middle lung lobes best heard?—ANSWER--Anterior chest
Where are the lower lung lobes best heard?—ANSWER--Posterior chest
What is the "envelope" lining between the lungs/chest wall?—ANSWER--Pleura
Visceral: lines the outside of the lungs
Parietal: lines the inside of chest wall and diaphragm
