BMS 300 EXAM 2 - CONCEPT TESTS/LAB
REPORTS QUESTIONS COMPLETE WITH
100% CORRECT ANSWERS
\.Trace the complete pathway of blood through the different types of blood
vessels starting with the blood leaving the heart. - ANSWERS✔-elastic arteries
muscular arteries
arterioles
capillaries
venules
veins
\.Which of the following is true?
The structure of the heart is directly related to its function as a muscular pump.
A key function of the cardiovascular system is to deliver oxygen, hormones,
immune cells, proteins, and nutrients to the body tissues.
,The left side of the heart acts as a muscular pump for the systemic circulation. -
ANSWERS✔-All of these are correct
\.Which of the following statements is true?
All vessels that carry blood away from the heart are called arteries.
All vessels that carry oxygenated blood are called veins.
All vessels that carry blood away from the heart are called veins.
All vessels that carry deoxygenated blood are called arteries. - ANSWERS✔-All
vessels that carry blood away from the heart are called arteries
\.In the lungs: - ANSWERS✔-a and b are true
carbon dioxide is released from the blood stream.
oxygen enters the blood stream
\.Stroke volume is equal to: - ANSWERS✔-EDV - ESV
,\.Which of the following is a measure of preload? - ANSWERS✔-contractility
end systolic volume
end diastolic volume
cardiac output
heart rate
\.______ stimulation increases contractility because it produces a greater
_________ at a given ________ - ANSWERS✔-increased sympathetic; tension;
muscle fiber length
\.Which of the following is a mechanism for increasing preload (end diastolic
volume)? - ANSWERS✔-stretching cardiac muscle
\.In the following list of characteristics, determine if the description applies to an
artery, a capillary or a vein. (Artery) - ANSWERS✔-has the highest pressure
has thick tunica media
carries blood away from the heart
, \.In the following list of characteristics, determine if the description applies to an
artery, a capillary or a vein. (Vein) - ANSWERS✔-carries blood toward heart
has the lowest pressure
thin tunica media
largest lumen-blood reservoir
\.In the following list of characteristics, determine if the description applies to an
artery, a capillary or a vein. (Capillary) - ANSWERS✔-smallest of blood vessels
site of nutrient exchange
\.What are varicose veins? - ANSWERS✔-evidence of faulty venous valves that
cause a back flow of blood in the limbs and extremities
\.Special adaptations help blood return to the heart since pressure is lower in the
veins. Match each mechanism of venous return with its appropriate definition.
during inspiration, pressure decreases in the thoracic cavity and "pulls" blood
toward the heart - ANSWERS✔-respiratory pump
