Pertaining to the heart and lungs is:
Cardiopulmonary
A mucous membrane lining the respiratory tract that warm, moistens, and filters inhaled air is__________
Mucosa
Rounded top of each lung is ________
apex
Muscular sheet that divides the thoracic cavity from the abdominal cavity
diaphragm
Exhaled gas that is a waste product of cellular metabolism. It is carried in the blood and by the hemoglobin in red blood cells.
Carbon dioxide
Body system that brings oxygen into the body and expels carbon dioxide.
Respiratory System
Wall of cartilage and bone that divides the nasal cavity into right and left sides is ____________
septum
Hollow sphere of cells in the lungs where oxygen and carbon dioxide are exchanged
alveolus
Two sets of muscles between the ribs that contract to pull the rubs up and out during inhalation or down and in during forceful exhalation is _________ ______
intercostal muscles
Eupnea
card/i is ____________
heart
Three scroll like projections of bone within the nasal cavity that increase surface area for warming air is _____
Turbinates
Small tubular air passageway that branches off from the bronchus and then branches into several alveoli. Its wall contain smooth muscle.
Bronchiole
smaller cavity within the thoracic cavity. It contains the trachea (and heart and esophagus)
mediastinum
Process of using oxygen to produce energy for cells. ________ produces carbon dioxide and other waste products.
metabolism
pulmon/o is _________-
lung
The throat; a shared passageway for both the respiratory and digestive systems is ____
pharynx
Small hairs that flow in waves to move foreign particles away from the lungs and toward the nose and the throat where they can be expelled:
cilia
pector/o- is ___________
chest
Compound formed when oxygen combines with the hemoglobin in red blood cells
spir/o- is _________ and __________
breathe and a coil
turbin/o- is: ___ ____ ______ ______
scroll like structure turbinate
Lidlike structure that seals off the larynx, so that swallowed food goes into the esophagus, not into the trachea
epiglottis
phren/o is _____ _____
diaphragm; mind
