Question

complete the path of oxygenated blood. the blood enters the left atrium and travels through the ____ valve and into the left ventricle. then it flows through the ____ valve to the aorta.
options:
aortic; mitral
mitral; aortic
pulmonary; tricuspid
tricuspid; pulmonary

Explanation:

To determine the correct valves, we recall the path of oxygenated blood: Oxygenated blood enters the left atrium. The valve between the left atrium and left ventricle is the mitral (bicuspid) valve. From the left ventricle, blood flows through the aortic valve to the aorta. So the first blank (between left atrium and left ventricle) is mitral, and the second blank (between left ventricle and aorta) is aortic. The option "mitral; aortic" matches this.

Answer:

B. mitral; aortic (assuming the options are labeled, and the second option is "mitral; aortic" as per the text in the image)
