HSC 101 EXAM 2 UPDATED ACTUAL QUESTIONS AND
CORRECT ANSWERS
Question:
What is the Cardiovascular System?
Answer:
Includes heart and all blood vessels Provides for tissue exchange of gases,
nutrients and wastes Also provides immunity
Question:
purpose of blood
Answer:
to transport oxygen, carbon dioxide, nutrients and the waste products of
metabolism
Question:
arterial system
Answer:
The system of arteries carrying blood away from the heart.
Question:
venous system
Answer:
Returns deoxygenated blood to the heart.
Question:
circulation
Answer:
Movement of blood through the body
Question:
Pressure Gradient (Blood)
Answer:
The pressure of blood is highest in the arteries and lowest in the veins, driving
blood flow through the circulatory system.
Question:
hydrostatic pressure
Answer:
the pressure within a blood vessel that tends to push water out of the vessel
Question:
Blood Pressure
Answer:
the pressure that is exerted by the blood against the walls of blood vessels
Question:
stroke volume
Answer:
The amount of blood ejected from the heart in one contraction.
, Question:
Cardiac Output
Answer:
heart rate x stroke volume
Question:
Healthy blood pressure
Answer:
120/80 mmHg
Question:
systolic blood pressure
Answer:
Pressure in arteries during heartbeats. (Top number)
Question:
diastolic blood pressure
Answer:
Pressure in the arteries when the heart re-laxes and ventricles fill with blood
(Bottom number)
Question:
Blood Vessels
Answer:
tubelike structures that carry blood throughout the body
Question:
Connective tissue
Answer:
A body tissue that provides support for the body and connects all of its parts
Question:
tunica externa
Answer:
outer layer of a blood vessel which connects it to surrounding tissues
Question:
tunica media
Answer:
The middle and thickest layer of tissue of a blood vessel wall, composed of
elastic tissue and smooth muscle cells that allow the vessel to expand or
contract in response to changes in blood pressure and tissue demand.
Question:
What are smooth muscles?
Answer:
Muscles that act on the lining of the body's passageways and hollow internal
organs.
Question:
Why do arteries have thicker smooth muscles than veins?
Answer:
Because they need to withstand muscle changes.
