Tunica externa (tunica adventitia)— Ans: epithelial cells,
connective tissue, elastic fibers
© 2026 Assignment
Tunica media— Ans: elastic fibers and smooth muscle
(usually the largest layer- controls the diameter)
Guru01 - Stuvia
Expert
Tunica intima (interna)— Ans: endothelial cells, simple
squamous, connective tissue
Aneurysm— Ans: is a weak point in the wall of a vessel,
bulging sac that pulsates with each heartbeat.
Continuous— Ans: tight junctions, creating a continuous and
uninterrupted lining, small gaps for exchange of gases via
simple diffusion
Fenestrated— Ans: contains pores fenestrations; allows for
slightly larger molecules to filter; found in places like the
kidney.
Sinusoidal— Ans: large openings allow the passage of larger
molecules such as proteins and formed elements; found in the
liver
Veins— Ans: contain valves; rely on the following to create
pressure to assist in returning blood to the heart:
, 2
vasoconstriction, valves, skeletal muscle pump, respiratory
pump, and cardiac suction.
Besides valves, veins contains what else ?— Ans: Veins
contain most of the blood at any given time and function as a
blood reservoir that can dramatically increase venous return to
the heart when systemic venoconstriction increases venous
return.
Blood Pressure (BP)— Ans: Blood pressure (BP) is the force
exerted by blood against a vessel's wall as it flows through
© 2026 Assignment
BP =?— Ans: systolic pressure/diastolic pressure
Guru01 - Stuvia
Expert
Systolic blood pressure refers to— Ans: refers to the pressure
in the arteries when the heart contracts and pumps blood into
the circulation.
Diastolic blood pressure represents the— Ans: the pressure
in the arteries when the heart is at rest between beats.
Pulse Pressure =— Ans: systolic pressure - diastolic pressure
*essay math problem know how to calculate MAP =— Ans:
(systolic pressure - diastolic pressure)/3 + diastolic pressure
****OR***
MAP= diastolic pressure + 1/3 pulse pressure
Example: Patient that has a BP of 120/80 mmHg. What is this
patient's MAP?
MAP = (120-80)/3 + 80
