What is arteries?
The blood that flows through two consecutive capillary networks before returning to the heart.
What is a Portal system ?
The force exerted by the blood against the vessel wall. It is highest in arteries as these are the first blood vessels it flows into from the heart and gradually decreases as it passes through arterioles, capillaries, venules and finally, veins.
What is Blood pressure ?
A brief stroke-like attack that, despite resolving within minutes to hours, still requires immediate medical attention to distinguish from an actual stroke.
What is a Transient ischemic attacks (TIAs)?
The blood vessels that carry blood towards the heart.

What is Tunica Media ?
The Tunica interna, Tunica media , Tunica externa.
What are the three wall layers of the arteries and veins ?
The most common route for blood
What is
heart --> arteries --> arterioles --> capillaries --> venules --> veins ?
The average pressure in a patient's arteries during one cardiac cycle. (Normal ranges are between 70 and 110 mm Hg).
What is a Mean arterial pressure (MAP) ?
The simple squamous epithelium overlying basement membrane and sparse layer of loose connective tissue. (acts as a barrier and secretes chemicals that stimulate dilation or constriction of the vessel)
What is Endothelium?
