connects the nasal and oral cavities to the larynx
which type of artery contains elastic lamella in its tunica media
communicates anteriorly with the external environment. lined with stratified squamous. It entraps large particles before entering air stream. Also contains sebaceous glands.
nostrils aka_____
principle extracellular component of the tunica adventitia of muscular arteries
sites of gas exchange in lungs
largest lymphatic vessel
stimulates arteriole vasoconstriction causing an increase in blood pressure.
conveys blood from heart to lungs and vice versa
which cells are the progenitor cells for type 1 alveolar cells
blood vessels that deliver blood to capillaries
branched tubuloaveolar serous glands that deliver proteinaceous secretions via ducts onto the olfactory surface
the middle layer of a blood vessel. consists primarily of circumferentially arrange smooth muscle cells.
true or fale: veins have a smaller lumen than arteries.
layer within the tracheal wall that consists of ciliated pseudostratified epithelium and an elastic, fiber rich lamina propria
this substance serves to moisten air and prevents dehydration of nasal epithelium
protein hormone of the heart that acts to inhibit renin secretion and aldosterone secretion. Also vasodialates, relaxing smooth muscle cells.
which cells in the tunica media cells secrete elastin, collagen (30% Type I and 70% Type III) and proteoglycans.
how are small arteries and arterioles distinguished
classification of olfactory epithelium
warming, moistening, and removal of particulate materials is known as ?
non cilated cells that have a characteristic dome shaped apical surface. They secrete a surface active agent that prevents luminal adhesion
the classification of type 1 alveolar cells
purkinje fibers are located where within endocardium
converts angiotensinogensecreted by the liver to angiotensinI
stem cells in respiratory and olfactory epithelium
true or false: olfactory cells are bipolar neurons that contain specialized cilia
smooth muscle tissue at arterial end of capillary which controls flow of blood to tissues
layer within the tracheal wall that consists of c-shaped hyaline cartilage rings
conveys fluids from tissues to blood
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.
medial wall of the respiratory segment in the nose
capillaries with small channels within its wall
small blood vessel providing direct artery-vein connection and bypassing capillaries
main nerve supply to nose
a protein secreted by the liver that inhibits serine proteinases such as elastase released by macrophages.
a sustained diastolic pressure about 90 mm Hg or sustained systolic pressure above 140 mm Hg
innermost layer of a vessel
classification of the epithelium of small bronchioles
derived from monocytes reside within the alveolar space.
ventricular folds are also known as
type 2 alveolar cells secrete
inner layer of endothelium, and subendothelial CT, middle layer of smooth muscle cells and CT, subendocardial layer
these type of arteries have a prominent internal elastic membrane
short thick hairs in the nasal cavity responsible for filtering air
which type of arteries have the highest pressures?
generates electrical impulses of the heart
opening of the larynx
layer within the tracheal wall that consists of slight denser CT than lamina propria
type 1 alveolar cells are connected via
in this lower conducting airway Cartilage plates are absent and replaced with smooth muscle.
layer of heart consisting of cardiac muscle
the classification of type 2 alveolar cells
how many layers of smooth muscle cells do arterioles have?
true or false: type I alveolar cells are able to replicate.
layer of mesothelial cells on outer layer of heart and underlying connective tissue
outermost blood vessel layer. merges with underlying CT layer.
vessels that collect blood from the capillary bed and return it to the heart
name the distinguishing features of veins vs arteries
diameter of capillary (in micrometers)
site of gas, nutrient and waste transfer
these type of arteries have more muscle cells in tunica media than elastic cells
smooth muscle of trachea
true or false: the tunica media of elastic arteries contian Collagen type 2 for strength
true or false: the tunica intima has its own basal lamina.
portion of the respiratory system where gas exchange occurs
arteries are classified based on which arterial wall layer
layer within the tracheal wall that consists of CT that binds trachea to adjacent structures
most numerous cells in the olfactory epithelium
tissue between alvelolar air spaces is
used to clinically decrease blood pressure.
serves as a conduit for air as well as organ of phonation
located at the dome of the nasal cavity and contains specialized olfactory mucosa
Chronic respiratory infections caused by poor mucociliary clearance due to immotile cilia (absent dynein arms)
what is the maximum number of layers of smooth muscle cells do small arteries have?
smallest arteries
converts angiotensin I to angiotensin II to increase blood pressure
Network of Autonomic Nerves located in tunica adventitia
specific phospholipid within surfactant, that accounts for most of the surface tension reducing properties
condition caused by the accumulation of fibrofatty intimal plaques
this portion of the respiratory system consist of airways that lead to sites of respiration within lung
