1403 Bronchiole Anatomy Study Resources

AirwayThe hollow part of the bronchus through which air is conducted.
AlveoliTiny air sacs where gas exchange occurs, connected by bronchioles.
ApexThe uppermost part of the lung, located just below the collarbone.
BaseThe bottom part of the lung that rests on the diaphragm.
BronchiolesThe smallest airways leading directly to the alveoli.
BronchusA major air passage of the lungs that branches from the trachea.
Cartilaginous RingsStructural supports that prevent the airway from collapsing.
Ciliated LiningLining of the bronchus made of ciliated epithelial cells that propel mucus.
Gland DuctsDucts connected to mucous glands, secreting mucus onto the bronchus lining.
HilumA medial region on each lung where the bronchi, blood vessels, and nerves enter and exit.
LumenThe central airway passage within the bronchus.
Mucous GlandsGlands that produce mucus to trap debris and microorganisms.
Pulmonary ArteryThe artery carrying deoxygenated blood to the lungs for oxygenation.
Pulmonary VeinThe vein carrying oxygenated blood away from the lungs back to the heart.
Secondary BronchiBranches of the primary bronchus that further subdivide into smaller passages.
TracheaThe windpipe, a tubular structure that facilitates the passage of air to the lungs.
TrabeculaeFibrous bands providing internal support within the spleen.
Vascular SinusesSpaces in the spleen where blood is exposed to macrophages for phagocytosis.
