Question

Which of the following shows the correct path of oxygenated blood from the lungs to the body cells?

A. R&L lungs superior & inferior vena cavae → R atrium → tricuspid valve R ventricle pulmonic valve pulmonary artery body cells
B. R&L lungs → pulmonary veins → R atrium mitral valve → R ventricle aortic valve aorta body cells
C. R&L lungs → pulmonary veins → L atrium mitral valve L ventricle aortic valve aorta body cells
D. Follow the yellow brick road, Follow the yellow brick road, Follow, Follow, Follow, Follow the yellow brick road

Which of the following states the correct path of deoxygenated blood from the body cells to the lungs?

A. Body cells superior & inferior vena cavae → R atrium → tricuspid valve R ventricle pulmonic valve pulmonary artery → lungs
B. Body cells pulmonary veins → R atrium mitral valve R ventricle aortic valve aorta → lungs
C. Body cells superior & inferior vena cavae → L atrium → tricuspid valve → L ventricle → pulmonic valve pulmonary artery → lungs
D. Body cells → arteries → arterioles capillaries venules → veins → lungs

Answer 1

The correct path of oxygenated blood from the lungs to the body cells is through the pulmonary veins, left atrium, left ventricle, and aorta.

Step-by-step explanation:

The correct path of oxygenated blood from the lungs to the body cells is option B: R&L lungs → pulmonary veins → R atrium mitral valve → R ventricle aortic valve aorta body cells.

This is because after oxygenating in the lungs, the oxygen-rich blood is transported by the pulmonary veins to the left atrium.

From there, it is pumped through the mitral valve into the left ventricle, and then through the aortic valve into the aorta to be distributed to the body cells.
