Blood vessels
arteries carry blood where
Away from the heart
Baroreceptors are found in the
carotid and aortic arch
What is the purpose of capillaries
Where gasses, nutrients, wastes, and hormones pass between the
blood and tissue fluid
What is hypertension
high blood pressure
The biggest arteries are
Conducting arteries
Capillaries do what
connect the smallest arteries to smallest veins to create circuits
Baroreceptors monitor
Blood pressure
Capillaries are composed of
endothelium and basal lamina
What is hypotension
chronic low blood pressure
The conducting ateries expand during when
Systole
Aorta, common carotid, subclavian, pulmonary trunk, and common iliac arteries are all examples of what
conducting arteries
Chemoreceptors are found where
Carotid body and the aortic body
Capillaries are distinguished by
their permeability
Peripheral resistance is used for
blood viscosity
vessel length
vessel radius
Function of distributing arteries
distribute blood to specific organs
Brachial, femoral, renal, and splenic arteries are all examples of
Distribution arteries
Functions of the carotid bodies
Monitor blood chemistry, Adjust respiratory rate to stabilize ph, co2, and o2, glossopharyngeal nerve
Organs that use fenestrated capilaries often require
rapid absorption or filtration
Vasodilation is brought on by
muscular passivity
These arteries Provide shortcuts allowing blood
to bypass capillary beds
Metarterioles
Sensory structures in the walls of major vessels monitor
Blood pressure and composition
Aortic bodies
Monitor blood chemistry, Adjust respiratory rate to stabilize ph, co2, and o2, glossopharyngeal nerve
vagus nerve
list the capillaries from least permeable to most permeable
Continuous capillaries
Fenestrated capillaries
Sinusoids
What are the ways of vasomotor control
1. Local control
autoregulation, reactive hyperemia, angiogenesis
2. Neural control
baroreflex, chemoreflex, medullary ischemic reflex
3. Hormonal control
The smooth muscle layers of these arteries consists of three-fourths of
wall thickness
