Cardio/Pulmonary
ventricular folds are also known as
Chronic respiratory infections caused by poor mucociliary clearance due to immotile cilia (absent dynein arms)
true or false: type I alveolar cells are able to replicate.
Single epithelial cell forms wall. closed wall.Sealed with occluding junction at edges
condition caused by the accumulation of fibrofatty intimal plaques
medial wall of the respiratory segment in the nose
smallest conducting bronchioles
ciliated cells form a functional structure the moves trapped particles from lungs
type 2 alveolar cells secrete
used to clinically decrease blood pressure.
true or false: veins have thinner walls than their arterial counterparts.
true or false: Surfactant prevents alveolus collapse upon exhalation by increasing surface tension
stem cells in respiratory and olfactory epithelium
inner layer of endothelium, and subendothelial CT, middle layer of smooth muscle cells and CT, subendocardial layer
true or fale: veins have a smaller lumen than arteries.
located at the dome of the nasal cavity and contains specialized olfactory mucosa
largest lymphatic vessel
bronchial arteries are branches of which main artery?
purkinje fibers are located where within endocardium
which type of artery contains elastic lamella in its tunica media
diameter of capillary (in micrometers)
tissue between alvelolar air spaces is
converts angiotensinogensecreted by the liver to angiotensinI
generates electrical impulses of the heart
the middle layer of a blood vessel. consists primarily of circumferentially arrange smooth muscle cells.
smallest arteries
conveys blood from heart to other tissues of the body and vice versa
specific phospholipid within surfactant, that accounts for most of the surface tension reducing properties
short thick hairs in the nasal cavity responsible for filtering air
arteries are classified based on which arterial wall layer
pauses in breathing
branched tubuloaveolar serous glands that deliver proteinaceous secretions via ducts onto the olfactory surface
layer within the tracheal wall that consists of c-shaped hyaline cartilage rings
main nerve supply to nose
decrease in blood pressure monitored by the kidneys results in the release of which enzyme?
involve leakage of blood past the Tunica intimaand into the spaces separating the layers of the wall. Blood forced in under maximum pressure dissects the layers apart.
layer within the tracheal wall that consists of CT that binds trachea to adjacent structures
Cardio/Pulmonary
name the distinguishing features of veins vs arteries
enzyme at the surface of alveolar endothelial cells activates angiotensin (arteriole vasoconstrictor), thus increasing blood pressure.
which type of arteries have the highest pressures?
which cells in the tunica media cells secrete elastin, collagen (30% Type I and 70% Type III) and proteoglycans.
what is the maximum number of layers of smooth muscle cells do small arteries have?
classification of the epithelium of small bronchioles
type 1 alveolar cells are connected via
these type of arteries have more muscle cells in tunica media than elastic cells
Network of Autonomic Nerves located in tunica adventitia
layer of heart consisting of cardiac muscle
connects the nasal and oral cavities to the larynx
Surfactant deficiency in some premature infants is a cause of
this portion of the respiratory system consist of airways that lead to sites of respiration within lung
how many layers of smooth muscle cells do arterioles have?
a protein secreted by the liver that inhibits serine proteinases such as elastase released by macrophages.
conveys fluids from tissues to blood
this protein hormone is a clinical marker for congestive heart failure
converts angiotensin I to angiotensin II to increase blood pressure
sites of gas exchange in lungs
layer within the tracheal wall that consists of ciliated pseudostratified epithelium and an elastic, fiber rich lamina propria
large arteries such as pulmonary artery and aorta are classified as?
clara cells secrete which protein
derived from monocytes reside within the alveolar space.
the classification of type 1 alveolar cells
these type of arteries have a prominent internal elastic membrane
Irregular lumen and incomplete basal lamina. Endothelial cells are separated by large gaps
two folds of mucosa that extend into the lumen of the larynx
recesses located above vocal cords
serves as a conduit for air as well as organ of phonation
layer within the tracheal wall that consists of slight denser CT than lamina propria
small blood vessel providing direct artery-vein connection and bypassing capillaries
system of vessels contained in the tunica adventitia . Supplies blood to vessels.
portion of the respiratory system where gas exchange occurs
which cells are the progenitor cells for type 1 alveolar cells
major component of venous walls
protein hormone of the heart that acts to inhibit renin secretion and aldosterone secretion. Also vasodialates, relaxing smooth muscle cells.
innermost layer of a vessel
Cardio/Pulmonary
non cilated cells that have a characteristic dome shaped apical surface. They secrete a surface active agent that prevents luminal adhesion
warming, moistening, and removal of particulate materials is known as ?
how are small arteries and arterioles distinguished

true or false: the tunica media of elastic arteries contian Collagen type 2 for strength
opening of the larynx
site of gas, nutrient and waste transfer
capillaries with small channels within its wall
layer within bronchus that is not present in trachea
the classification of type 2 alveolar cells
these cells secrete mucinogen
caused by obstruction of the upper airway. It is characterized by repetitive pauses in breathing during sleep, despite the effort to breathe, and is usually associated with a reduc
true or false: the tunica intima has its own basal lamina.
the irreversible loss of pulmonary elasticity due to increased elastase activity brought about by chronic infections or alpha 1-antitrypsin deficiency.
true or false: olfactory cells are bipolar neurons that contain specialized cilia
this substance serves to moisten air and prevents dehydration of nasal epithelium
shelflike bony projections that increase surface area within nasal septum as well increase turbulence of airflow for better conditioning
a sustained diastolic pressure about 90 mm Hg or sustained systolic pressure above 140 mm Hg
where do the lesions in artherosclerotic vessels develop?
classification of olfactory epithelium
blood vessels that deliver blood to capillaries
smooth muscle of trachea
skeletal muscle within vocal cords
communicates anteriorly with the external environment. lined with stratified squamous. It entraps large particles before entering air stream. Also contains sebaceous glands.
