vena cava,
lower esophagus, lower trachea
What makes up the external 12 thoracic vertebrae
thorax? 12 pairs of ribs
sternum
Sternum includes... manubrium, body, xiphoid process
What comprises the upper airway? nose, mouth, pharynx, larynx, trachea
What is the function of the upper conduct air to lower airway, protect lower
airway? airway
from foreign matter, warm, filter, and
humidify
inspired air
What comprises the lower airway? mainstem, segmental, and subsegmental
bronchi,
terminal bronchioles, and alveoli
What is the function of the lower exchange of oxygen and carbon dioxide in
airway? alveoli
,Function of the Respiratory provide oxygen to the body for energy
System production,
remove CO2 as a waste product, maintain
homeostasis (acid-base balance), maintain
heat
exchange
Ventilation the movement of gases in and out of the
lungs
Inspiration active process stimulated by chemical
receptors in
the aorta, diaphragm contracts pushing the
abdominal contents downward, intercostal
muscles
push chest forward
Expiration A passive process in which the intercostal
(rib)
muscles and the diaphragm relax, causing
the chest
cavity to decrease in size and forcing air
from the
lungs
Pulmonary Circulation the movement of blood between the heart
and the
lungs for gas exchange
, Diffusion exchange of respiratory gases (O2 and
CO2) in the
alveoli and capillaries, moves from areas
of high
concentration to areas of low concentration
Oxygen Transport Lungs and cardiovascular system
Carbon Dioxide Transport diffuses into red blood cells and is
hydrated into
carbonic acid
Anterior Thoracic Landmarks Costal Angle = less than 90°
Intercostal Spaces (are named for rib
above it) =
apical pulses are found at 5th intercostal
space,
