Structure/Function
The layer of blood vessels that contains elastic connective tissue, allowing the vessel to stretch.
HINT: This layer is thickest in the arteries
Tunica Media
T/F: Hydrostatic pressure pulls water into the vessel
False. It pushes water out of the vessel
What is the definition of blood pressure?
measurement of the pressure inside blood vessels during systole compared to during diastole
Capillaries branch off of this type of blood vessel.
Arterioles
Capillaries are made of this layer only to allow for easy gas exchange
Tunica intima
"Filtration" is another word for this type of pressure.
Blood hydrostatic pressure
the last Korotkoff sound
List the three types of capillaries
Bonus: Where are each of them found?
The aorta is an example of which type of blood vessel?
Elastic artery (conducting vessel)
Where does the excess fluid from filtration go?
The lymphatic system
Where is pulse measured?
Pulse points
List three examples
Vasoconstriction and vasodilation is done by these types of blood vessels.
(HINT: they are located right near the capillary beds)
arterioles
The formula for net filtration pressure is:
HINT: Net filtration pressure = outward forces - inward forces
NFP = (PC+OPIF) - (PIF+OPC)
What is the formula for measuring blood pressure?
blood pressure = systolic pressure - diastolic pressure
Capillary exchange occurs through these three mechanisms:
Diffusion, Transcytosis, and Bulk flow
BONUS: Define each term
Proteins and blood cells can be exchanged through this type of capillary
(HINT: they have large fenestrations)
Sinusoid Capillaries
Blood colloid osmotic pressure is caused by the collection of what inside the vessel?
Proteins, ions, and formed elements.
How does polycythemia affect blood pressure?
It increased blood pressure
Explain.
Which type of capillary is made of a layer of endothelial cells with tight junctions
Continuous capillaries
Bonus: what are these capillaries permeable to?
