Cardio/Pulmonary
condition caused by the accumulation of fibrofatty intimal plaques
opening of the larynx
communicates anteriorly with the external environment. lined with stratified squamous. It entraps large particles before entering air stream. Also contains sebaceous glands.
tissue between alvelolar air spaces is
site of gas, nutrient and waste transfer
true or false: type I alveolar cells are able to replicate.
derived from monocytes reside within the alveolar space.
purkinje fibers are located where within endocardium
stimulates arteriole vasoconstriction causing an increase in blood pressure.
specific phospholipid within surfactant, that accounts for most of the surface tension reducing properties
smooth muscle of trachea
large arteries such as pulmonary artery and aorta are classified as?
inner layer of endothelium, and subendothelial CT, middle layer of smooth muscle cells and CT, subendocardial layer
main nerve supply to nose
blood vessels that deliver blood to capillaries
smooth muscle tissue at arterial end of capillary which controls flow of blood to tissues
bronchial arteries are branches of which main artery?
Single epithelial cell forms wall. closed wall.Sealed with occluding junction at edges
recesses located above vocal cords
type 1 alveolar cells are connected via
smallest conducting bronchioles
protein hormone of the heart that acts to inhibit renin secretion and aldosterone secretion. Also vasodialates, relaxing smooth muscle cells.
Chronic respiratory infections caused by poor mucociliary clearance due to immotile cilia (absent dynein arms)
a sustained diastolic pressure about 90 mm Hg or sustained systolic pressure above 140 mm Hg
layer within the tracheal wall that consists of slight denser CT than lamina propria
portion of the respiratory system where gas exchange occurs
layer within the tracheal wall that consists of CT that binds trachea to adjacent structures
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?
layer within the tracheal wall that consists of c-shaped hyaline cartilage rings
the irreversible loss of pulmonary elasticity due to increased elastase activity brought about by chronic infections or alpha 1-antitrypsin deficiency.
non cilated cells that have a characteristic dome shaped apical surface. They secrete a surface active agent that prevents luminal adhesion
where do the lesions in artherosclerotic vessels develop?
Network of Autonomic Nerves located in tunica adventitia
stem cells in respiratory and olfactory epithelium
major component of venous walls
skeletal muscle within vocal cords
Cardio/Pulmonary
what is the maximum number of layers of smooth muscle cells do small arteries have?
located at the dome of the nasal cavity and contains specialized olfactory mucosa
which cells in the tunica media cells secrete elastin, collagen (30% Type I and 70% Type III) and proteoglycans.
largest lymphatic vessel
conveys fluids from tissues to blood
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
two folds of mucosa that extend into the lumen of the larynx
pauses in breathing
capillaries with small channels within its wall
Irregular lumen and incomplete basal lamina. Endothelial cells are separated by large gaps
in this lower conducting airway Cartilage plates are absent and replaced with smooth muscle.
a protein secreted by the liver that inhibits serine proteinases such as elastase released by macrophages.
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 ciliated pseudostratified epithelium and an elastic, fiber rich lamina propria
this protein hormone is a clinical marker for congestive heart failure
serves as a conduit for air as well as organ of phonation
classification of olfactory epithelium
generates electrical impulses of the heart
layer of mesothelial cells on outer layer of heart and underlying connective tissue
medial wall of the respiratory segment in the nose
which type of artery contains elastic lamella in its tunica media
smallest arteries
principle extracellular component of the tunica adventitia of muscular arteries
sites of gas exchange in lungs
these type of arteries have more muscle cells in tunica media than elastic cells
primary function of these cells is to exchange of O2and CO2between the airspace and blood.
shelflike bony projections that increase surface area within nasal septum as well increase turbulence of airflow for better conditioning
the middle layer of a blood vessel. consists primarily of circumferentially arrange smooth muscle cells.
Surfactant deficiency in some premature infants is a cause of
most numerous cells in the olfactory epithelium
warming, moistening, and removal of particulate materials is known as ?
ciliated cells form a functional structure the moves trapped particles from lungs
clara cells secrete which protein
true or fale: veins have a smaller lumen than arteries.
disorder characterized by Thick mucous. Chronic respiratory infections
classification of respiratory epithelium
layer within bronchus that is not present in trachea
Cardio/Pulmonary
branched tubuloaveolar serous glands that deliver proteinaceous secretions via ducts onto the olfactory surface
nostrils aka_____
how are small arteries and arterioles distinguished
arteries are classified based on which arterial wall layer
the classification of type 2 alveolar cells
small blood vessel providing direct artery-vein connection and bypassing capillaries
converts angiotensinogensecreted by the liver to angiotensinI
these type of arteries have a prominent internal elastic membrane
used to clinically decrease blood pressure.
true or false: Surfactant prevents alveolus collapse upon exhalation by increasing surface tension
enzyme at the surface of alveolar endothelial cells activates angiotensin (arteriole vasoconstrictor), thus increasing blood pressure.
connects the nasal and oral cavities to the larynx
layer of heart consisting of cardiac muscle
true or false: veins have thinner walls than their arterial counterparts.
which cells are the progenitor cells for type 1 alveolar cells
decrease in blood pressure monitored by the kidneys results in the release of which enzyme?
name the distinguishing features of veins vs arteries
ventricular folds are also known as
outermost blood vessel layer. merges with underlying CT layer.
these cells secrete mucinogen
converts angiotensin I to angiotensin II to increase blood pressure
this substance serves to moisten air and prevents dehydration of nasal epithelium
conveys blood from heart to other tissues of the body and vice versa
diameter of capillary (in micrometers)
true or false: the tunica intima has its own basal lamina.
innermost layer of a vessel
classification of the epithelium of small bronchioles
true or false: the tunica media of elastic arteries contian Collagen type 2 for strength
system of vessels contained in the tunica adventitia . Supplies blood to vessels.
vessels that collect blood from the capillary bed and return it to the heart
