Trace the path of a red blood cell through the heart, starting in the right
ventricle:
1
,a. left atrium
b. right atrium

d. pulmonary circuit
e. systemic circuit - Ansd, a, c, e, b,
What is the function of the heart valves? - AnsTo passively keep blood
flowing in the proper direction.
Which components does the cardiovascular system comprise? - AnsHeart,
blood vessels, blood
Which of the following is true regarding pulmonary circulation? -

Which of the following statements about the structure of the heart is (are)
true? - Ans-the left ventricular wall is thicker than the right
-the structure of the atrioventricular and semilunar valves help to ensure
that the blood flows in only one direction through the heart and innermost
layer of the epithelial cells, the endothelium lines the entire inside of the
cardiovascular system
Which of the following statements about the systemic circuit is true? -
AnsBlood flow to each organ can be independently regulated.
2
, Why is the left ventricle muscle thicker than the right ventricle muscle? -
AnsThis difference is due to the greater pressure that the left ventricle has
