CORRECT DETAILED SOLUTIONS LATEST UPDATED

Question: Humoral vasodilators that regulate vascular function - CORRECT
ANSWER✔✔Histamine, Bradykinin, many Prostaglandins.
Question: Afterload - CORRECT ANSWER✔✔The force/resistance the heart must overcome to
pump/eject the blood out of the heart into the arteries.
Question: Intracapillary fluid pressure and Interstitial fluid pressure - CORRECT
ANSWER✔✔Movement of fluid between the capillary bed and interstitial spaces is continuous.
Equilibrium exists as long as equal amounts of fluid enter and leave the interstitial spaces.
Question: Stroke volume - CORRECT ANSWER✔✔The amount of blood pumped out or ejected
with each beat.
, Page 2 of 43
Question: Cardiac reserve - CORRECT ANSWER✔✔This is the overall ability of the heart to
increase its pumping capacity from its resting state to its maximum capacity.
Question: Cardiac output - CORRECT ANSWER✔✔Amount of blood the heart pumps each
minute.
Q:Four main functions of the circulatory system - CORRECT ANSWER✔✔Deliver oxygen, carry
waste products, circulates electrolytes and hormones, transport various immune functions.
Question: Two parts of the circulatory system - CORRECT ANSWER✔✔Pulmonary & systemic
circulation.
Question: Components of the pulmonary circulation - CORRECT ANSWER✔✔Right heart,
pulmonary artery, capillaries, and veins.
, Page 3 of 43
Question: Components of the systemic circulation - CORRECT ANSWER✔✔Left heart, aorta and
its branches, capillaries supplying the brain/peripheral tissues, and systemic venous system and
the vena cava.
Question: Two types of circulation - CORRECT ANSWER✔✔Pulmonary and systemic.
Question: Function of the arteries in the pulmonary and systemic circulations - CORRECT
ANSWER✔✔Arteries and arterioles function as a distribution system to move blood to the
tissues.
Question: Function of the capillaries in the pulmonary and systemic circulations - CORRECT
ANSWER✔✔Capillaries serve as an exchange system where transfer of gases, nutrients, and
wastes takes place.
Question: Function of the veins in the pulmonary and systemic circulations - CORRECT
ANSWER✔✔Venules and veins serve as collection and storage vessels that return blood to the
heart.

Question: Higher pressure pump in the circulatory system - CORRECT ANSWER✔✔Arterial.
Question: Primary function of the heart's one-way valves - CORRECT ANSWER✔✔Prevent
backflow of blood.
Question: Jugular vein distention suggestive of - CORRECT ANSWER✔✔Severe right sided heart
failure. (swollen neck veins).
Question: Preload - CORRECT ANSWER✔✔Volume of blood in heart's ventricles just before it
pumps out like filling a balloon w/water.
Question: Importance of cardiac reserve - CORRECT ANSWER✔✔It is important to be able to do
tedious activities like exercise.
Question: Baroreceptors - CORRECT ANSWER✔✔Located in the aorta/arteries and respond to
changes in arterial wall due to fluctuations in BP Stretch sensitive receptors Monitor blood
pressure.
